Spaceflight does some weird things to astronauts’ bodies

Published

on

Astronaut Scott Kelly famously lived and worked on the International Space Station for 340 days—the longest time an American has spent in space. His mission gave scientists some vital insight into what happens to the human body during long-duration stays in orbit. That’s because Kelly has an identical twin, Mark (also an astronaut, and now soon to be a US senator). The Kelly twins offered scientists a rare opportunity: as they studied what happened to Scott’s body during his year in space, they had the benefit of a control subject, Mark, who stayed on Earth.

The NASA Twins Study provided more evidence for what we already suspected. In a confined capsule under microgravity and prolonged exposure to radiation, the immune system takes a hit, the eye changes shape for the worse, and there’s some significant loss in muscle and bone mass.

But we also learned about some surprising effects. Kelly experienced changes in his gut microbiome, his cognitive abilities slowed down, certain genes would turn off and on, and his chromosomes experienced structural changes. 

“The Twins Study gave us a first sketch of the human body’s molecular responses to spaceflight, but these outlines needed to be filled in,” says Christopher Mason, an associate professor of physiology and biophysics at Weill Cornell Medicine. “The changes we saw needed more context and replication. We needed additional studies to map out the frequency of the changes we observed in other astronauts, and other organisms, that go into space, and also to see if the degree of change was similar for shorter missions.”

That brings us to a new package of research that builds on the Twins Study, reanalyzing some of the original data with new techniques and providing comparisons with other astronauts. In a set of 19 studies published today in a slew of different journals (along with 10 preprints still under peer review), researchers like Mason (a senior author on several of the papers) studied the physiological, biochemical, and genetic changes that occurred in 56 astronauts (including Kelly) who have spent time in space—the largest study of its kind ever conducted. 

The new papers, which incorporate results from cell-profiling and gene-sequencing techniques that have become easier to run only recently, reveal that “there are some features of spaceflight that consistently appear in humans, mice, and other animals when they go to space,” says Mason. “There appears to be a core mammalian set of adaptations and responses to the rigors of spaceflight.” 

The good, the bad, and the inexplicable

The researchers highlight six biological changes that occur in all astronauts during spaceflight: oxidative stress (an excessive accumulation of free radicals in the body’s cells), DNA damage, dysfunction of the mitochondria, changes in gene regulation, alterations in the length of telomeres (the ends of chromosomes, which shorten with age), and changes in the gut microbiome. 

Of these six changes, the biggest and most surprising one for scientists was mitochondrial dysfunction. Mitochondria play a critical role in producing the chemical energy necessary to keep cells—and by extension, tissue and organs—functional. Researchers found irregular mitochondrial performance in dozens of astronauts and were able to broadly characterize these changes thanks to new genomics and proteomics techniques. Afshin Beheshti, a bioinformatician at NASA and senior author of one study, says mitochondrial suppression helps explain how many of the problems astronauts experiment (like immune system deficiencies, disrupted circadian rhythm, and organ complications) are actually holistically related to each other, since they all rely on the same metabolic pathways.

“When you’re in space, it’s not just one are or organ that’s affected, it’s the whole body that’s affected,” says Beheshti. “We started connecting the dots.”

Other research homed in on problems observed at the genetic level. The Twins Study showed that Kelly’s telomeres got longer in space before shrinking back to normal or even shorter lengths soon after he returned to Earth. Telomeres are supposed to shorten with age, so lengthening makes little sense, and the Twins Study didn’t provide enough data to prompt any real conclusions as to why it happened and what the effects were. 

Susan Bailey, a Colorado State University expert on telomere research and a senior author for several of the papers, says the new research found that 10 other astronauts experienced the same telomere lengthening Kelly did irrespective of mission duration—as well as the same telomere shrinking once they came back to Earth. 

Notably, one of the papers in the new package found that longer telomeres were also associated with climbers of Mount Everest. For Bailey and her colleagues, this suggests that telomere lengthening is affected by oxidative stress—something that climbers and astronauts both experience, and that disrupts proper telomere maintenance. 

They are still trying to pinpoint how these pathways work and exactly what the consequences could be (it’s probably not a secret to longevity), but “we now have a foundation to build on—we know what to look for and be aware of in future astronauts on long-duration [and deep space] exploration missions,” she says. 

Though some of the changes are unexpected, many are no cause for concern. “What is amazing to me is how well we adapt to space,” says Jeffrey Sutton, director of the Baylor College of Medicine’s Center for Space Medicine, who was not involved with the new research. Blood cell mutations decreased in Kelly while he was in space (a total surprise for Mason). Astronauts also exhibited decreased levels of biomarkers associated with aging and increased levels of microRNAs that regulate the vascular system’s response to radiation damage and microgravity. One of the strangest findings was that astronauts’ gut microbiomes managed to bring space microbes found on the ISS back to Earth.

“The studies individually and collectively are truly impressive,” says Sutton. “We have entered a new era of space biomedical research, where the approaches and tools of precision and translational medicine are being applied to advance our understanding of human adaptation to space.”

Long-haul worries

Ultimately, however, the data highlights just how much havoc and stress even the healthiest bodies face during space missions—which should have an impact on planning for longer missions. “I don’t think we’re close to sending untrained people into space for really long periods of time,” says Scott Kelly. 

Physiologically, he thinks it’s probably safe to send people to Mars and back. In the distant future, however, “instead of going to Mars, we’re going to be going to the moons of Jupiter or Saturn,” he says. “You’re going to be in space for years. And at that point, we’ll have to take a closer look at artificial gravity as a mitigation. I wouldn’t want to be arriving on the surface of another planetary body and not be able to function. A year or so is workable. Several years probably isn’t.”

We’re still far away from having to evaluate those kinds of risks. Mason and his colleagues suggest that there should be pharmacological strategies for reducing the impact of gravity on the bodies of returning astronauts. 

Sutton believes precision medicine could play a huge role in tailoring those drugs to protect astronauts against the effects of microgravity and radiation. And the shared biological responses between astronauts and Mount Everest climbers suggest that some interventions used to protect extreme sports athletes from oxidative stress could be applied to astronauts too. 

What we need is more data—and more populations to use for comparison. Mason, Bailey, and their colleagues want to collect cell and gene profiles of more astronauts, especially those going on future year-long missions. They also want to study people who’ve experienced other conditions similar in some way to spaceflight, such as radiotherapy patients, pilots, and flight attendants. 

“The more we know about the health effects of long-duration spaceflight, the better able we will be to help maintain the health and performance of astronauts during and after spaceflight,” says Bailey. “Such knowledge benefits those of us on Earth as well—we are all concerned about getting older, and being in poor health.”

Instacart to eliminate about 2,000 jobs and GitHub head of HR resigns

Published

on

Hey y’all. You’ve just landed on Human Capital, the weekly newsletter that details the latest in labor, and diversity and inclusion in tech. The week kicked off with GitHub making a public apology to the person the company terminated for cautioning his employees about Nazis in D.C. on the day of the insurrection at the U.S. Capitol.

Later in the week, Google revoked corporate access from AI ethicist Margaret Mitchell in what some are saying is reminiscent of the company’s treatment of Dr. Timnit Gebru. Meanwhile, Instacart is making some changes to its platform that will result in job loss. 

Sign up below to get this in your email every Friday at 1 p.m. PT.

GitHub’s head of HR resigns; company offers fired Jewish employee his job back

A GitHub internal investigation revealed the company made “significant errors of judgment and procedure” in the firing of the Jewish employee who cautioned his coworkers about the presence of Nazis in the D.C. area on the day of insurrection at the U.S. Capitol.

In a blog post, GitHub COO Erica Brescia said the company’s head of HR took full responsibility for what happened and resigned from the company yesterday. GitHub did not disclose the name of the person who resigned, but it’s widely known that Carrie Olesen was the chief human resources officer at GitHub.

GitHub said it has “reversed the decision to separate with the employee” and is talking to his representative.

“To the employee we wish to say publicly: We sincerely apologize,” Brescia said in the blog post. However, the terminated employee previously told me that he did not want his job back but instead some other form of reconciliation.

Google AI ethicist under investigation 

Google is investigating AI ethicist Margaret Mitchell for reportedly using automated scripts to find examples of mistreatment of Dr. Timnit Gebru, according to Axios. Gebru says she was fired from Google while Google has maintained that she resigned. In a statement to Axios, Google said the company had locked Mitchell’s account:

Our security systems automatically lock an employee’s corporate account when they detect that the account is at risk of compromise due to credential problems or when an automated rule involving the handling of sensitive data has been triggered. In this instance, yesterday our systems detected that an account had exfiltrated thousands of files and shared them with multiple external accounts. We explained this to the employee earlier today.

The recently-formed Alphabet Workers Union made a statement saying it was concerned by Mitchell’s suspension of corporate access:

“Regardless of the outcome of the company’s investigation, the ongoing targeting of leaders in this organization calls into question Google’s commitment to ethics—in AI and in their business practices. Many members of the Ethical AI team are AWU members and the membership of our union recognizes the crucial work that they do and stands in solidarity with them in this moment.”

Google’s Sundar Pichai to meet with HBCU leaders

At least five HBCU presidents are scheduled to meet with Google CEO Sundar Pichai and Chief Diversity Officer Melonie Parker later this month to discuss recent allegations of racism and discrimination at the company, according to CNN. Additionally, the goal of the meeting is to ensure HBCUs have a good relationship with Google and that the company offers a good environment for its students and graduates.

Context:

Amazon launches anti-union website

Ahead of Amazon warehouse workers in Alabama gearing up to vote on whether to form a union, Amazon launched an anti-union website. Called Do It Without Dues, the site aims to dissuade workers from voting to unionize.

Instacart plans to terminate nearly 2,000 jobs 

Instacart plans to lay off nearly 2,000 of its workers, including the 10 workers from the Kroger-owned Mariano’s who unionized early last year, Vice reports. These workers are responsible for in-store shopping and packing of groceries.

According to Vice, 10 of the workers affected unionized with the United Food and Commercial Workers Local 1546 in Skokie, Illinois. However, they have yet to negotiate a contract with Instacart, according to Vice. Instacart notified the union of the planned changes earlier this week. In the letter, Instacart said it planned to stop using in-store shoppers at Kroger-owned stores, which includes the Mariano’s store in Skokie, in Q1 and Q2 of this year, but no earlier than mid-March.

How VCs and founders see 2021 differently

Published

on

Welcome back to The TechCrunch Exchange, a weekly startups-and-markets newsletter. It’s broadly based on the daily column that appears on Extra Crunch, but free, and made for your weekend reading. Click here if you want it in your inbox every Saturday morning.

Ready? Let’s talk money, startups and spicy IPO rumors.


We’re shaking things up this weekend in the newsletter, focusing on a series of larger themes and news items instead of having a few discrete sections. Why? Because there was too much to fit into our usual format. If you were a fan of the original layout, we’ll be back to it next week.

Today we’re talking Coinbase’s growth, how Juked.gg tapped the equity crowdfunding market, a noodle or two on the a16z media game, Talkspace’s SPAC, VC and founder predictions for 2021, and where’s the right place to found a company.

Sound good? Let’s get into it!

Coinbase’s deposits scale ahead of IPO

Thanks to Kazim Rizvi of Drop, parent company to Cardify which provides data on consumer spending, we have a look into how quickly deposits have scaled at American cryptocurrency platform Coinbase. As Coinbase has filed to go public, and we’re eagerly anticipating its eventual S-1 filing, we were stoked to get a directional look at how quickly consumer interest was growing for the assets it helps folks buy.

They are scaling rapidly. Using the first week of January 2019 as a baseline, by the last week of December 2020 deposits and withdrawals from Coinbase had grown by more than 12x apiece. That’s staggering growth, and while the data is somewhat volatile — and we’d treat it as directional instead of exact — on a week-to-week basis, it underscores how well companies like Coinbase may be performing as Bitcoin booms once again, bringing in more trading interest and consumer demand.

Via Cardify, Cardify data.

The Cardify data also indicates a multiplying of new customer acquisition at Coinbase over the same time period, and deposits scaling alongside the price of Bitcoin. As Bitcoin has topped the $30,000 mark recently, sharply higher than in recent quarters, the price gains may have helped Coinbase not only a solid Q4 2020, but perhaps put it on a path for a bonkers Q1 2021 as well.

If we were 10/10 excited about the Coinbase S-1 before this dataset, we’re now a heckin’ 12/10.

Equity crowdfunding seven-figures for esports content

Esports is super cool and if you don’t agree, you are incorrect. But it doesn’t matter if you or I are right or not on the question, as the market has largely decided that competitive gaming is worth time, attention and investors’ money.

The proliferation of esports leagues and games and the like has led to a decidedly fragmented universe, however, lacking a central hub akin to what ESPN provides the world of traditional sports.

But not to worry, Juked.gg just raised capital to build a content hub for esports. This means that old folks like myself can still find out when tournaments are happening, and enjoy a dabble of League of Legends or Starcraft 2 pro play when we can, sans hunting around the internet for dates and times.

Juked.gg went through 500 Startups (more on its class here), catching our eye at the time as a neat nexus for esports-related content. Now flush with a little over $1 million that it raised on the Republic platform, it has big plans.

The Exchange spoke with Juked.gg’s co-founder and CEO Ben Goldhaber about his company’s performance to date. Per Goldhaber, Juked has scaled from 500 users when it launched in late 2019, to 50,000 in December of 2020. Ahead, Juked may invest more in journalism, more into social features, and more into user-generated content. We’ll have more on Juked as it gets its vision built, now powered by over a million dollars from 2,524 investors, each betting that the startup is building the right product to help unify a growing, if distributed, entertainment category.

The a16z media push

To preserve our collective sanity, I’m not going to bang on at length here, but building out content at a VC firm is not new. Hell, how long ago did the First Round Review launch? What a16z appears to have in mind is different in scale, not substance. We chatted about it on Equity this week, in case you need more on the matter.

Talkspace’s maybe-not-stupid SPAC

While it is enjoyable to mock SPACs, featuring as many do companies that are nascent to say the least, not all SPAC-led debuts are as silly as the rest. This is the case with the impending Talkspace deal, the deck for which you can read here.

What matters is this set of charts:

Look at that! Historical revenue growth! Improving gross margins! Rising gross profit!

You may argue that the company is not really worth an enterprise value of $1.4 billion that it will sport after its combination with Hudson Executive Investment Corp., but, hey, at least it’s a real business.

How VCs and founders see 2021 differently

Seed VC NFX dropped a VC and founder survey the other day that I’ve been meaning to share with you. You can read the whole thing here, if you’d like.

I have two pull-outs for you this morning:

  1. VCs are more bullish on the economy than founders, with around 30% of founders expecting consumer spending to stay flat or decline, positions that only around 17% of VCs agreed with.
  2. And when it comes to leaving the Bay Area — yes, that chestnut again — 35% of founders have itchy feet, while just 20% of investors are similarly inclined. I think this is because the latter have houses in the Bay Area while most founders do not. But it should temper the view that all the money and talent are leaving. They aren’t.

There’s no place like no place

Initialized Capital put together some data on where founders think it is best to found a company. In 2020, nearly 42% of surveyed founders said the Bay Area. By 2021 that number had slipped to a little over 28%, with a plurality of 42% indicating that a distributed company is the best way to go.

I hear about this a lot from early-stage founders. They are often building what I call micro-multinationals, small companies that have a few employees in one country, and then a handful in others. Making that setup work is going to be a hotspot for HR software I reckon.

Regardless, the requirement of founding companies in the Bay Area is kaput. The advantages of founding there will linger much longer.

Coming up!

Coming up on The Exchange next week: The first entries of our new $50 million ARR series, featuring interviews with Assembly, SimpleNexus, Picsart, OwnBackup and others. And we have some $100 million ARR interviews in the can, as well.

Finally, to keep the The Powers That Be happy, The Exchange covered some neat stuff this week, including American VC results, fintech and unicorn venture capital, European and Asian venture capital results, how the IPO market is even more bonkers than you thought, and notes on what Qualtrics may be worth when it goes public.

Hugs, and let’s all get a nap in,

Augmented reality and the next century of the web

Published

on

Howdy friends, this is the web version of my Week in Review newsletter, it’s here to entice you to sign up and get it in your inbox every week.

Last week, I showcased how Twitter was looking at the future of the web with a decentralized approach so that they wouldn’t be stuck unilaterally de-platforming the next world leader. This week, I scribbled some thoughts on another aspect of the future web, the ongoing battle between Facebook and Apple to own augmented reality. Releasing the hardware will only be the start of a very messy transition from smartphone-first to glasses-first mobile computing.

Again, if you so desire you can get this in your inbox from the newsletter page, and follow my tweets @lucasmtny


The Big Thing

If the last few years of new “reality” tech has telegraphed anything, it’s that tech companies won’t be able to skip past augmented reality’s awkward phase, they’re going to have to barrel through it and it’s probably going to take a long-ass time.

The clearest reality is that in 2021 everyday users still don’t seem quite as interested in AR as the next generation of platform owners stand to benefit from a massive transition. There’s some element of skating to where the puck is going among the soothsayers that believe AR is the inevitable platform heir etc. etc., but the battle to reinvent mobile is at its core a battle to kill the smartphone before its time has come.

A war to remake mobile in the winner’s image

It’s fitting that the primary backers of this AR future are Apple and Facebook, ambitious companies that are deeply in touch with the opportunities they could’ve capitalized on if they could do it all over again.

While Apple and Facebook both have thousands of employees toiling quietly in the background building out their AR tech moats, we’ve seen and heard much more on Facebook’s efforts. The company has already served up several iterations of their VR hardware through Oculus and has discussed publicly over the years how they view virtual reality and augmented reality hardware converging. 

Facebook’s hardware and software experiments have been experimentations in plain sight, an advantage afforded to a company that didn’t sell any hardware before they started selling VR headsets. Meanwhile Apple has offered up a developer platform and a few well-timed keynote slots for developers harnessing their tools, but the most ambitious first-party AR project they’ve launched publicly on iOS has been a measuring tape app. Everything else has taken place behind closed doors.

That secrecy tends to make any reporting on Apple’s plans particularly juicy. This week, a story from Bloomberg’s Mark Gurman highlights some of Apple’s next steps towards a long-rumored AR glasses product, reporting that Apple plans to release a high-end niche VR device with some AR capabilities as early as next year. It’s not the most surprising but showcases how desperate today’s mobile kingpins are to ease the introduction of a technology that has the potential to turn existing tech stacks and the broader web on their heads.

Both Facebook and Apple have a handful of problems getting AR products out into the world, and they’re not exactly low-key issues:

  1. hardware isn’t ready
  2. platforms aren’t ready
  3. developers aren’t ready
  4. users don’t want it yet

This is a daunting wall, but isn’t uncommon among hardware moonshots. Facebook has already worked its way through this cycle once with virtual reality over several generations of hardware, though there were some key difference and few would call VR a mainstream success quite yet.

Nevertheless, there’s a distinct advantage to tackling VR before AR for both Facebook and Apple, they can invest in hardware that’s adjacent to the technologies their AR products will need to capitalize on, they can entice developers to build for a platform that’s more similar to what’s coming and they can set base line expectations for consumers for a more immersive platform. At least this would all be the case for Apple with a mass market VR device closer to Facebook’s $300 Quest 2, but a pricey niche device as Gurman’s report details doesn’t seem to fit that bill quite so cleanly.

The AR/VR content problem 

The scenario I’d imagine both Facebook and Apple are losing sleep over is that they release serviceable AR hardware into a world where they are wholly responsible for coming up with all the primary use cases.

The AR/VR world already has a hefty backlog of burnt developers who might be long-term bullish on the tech but are also tired of getting whipped around by companies that seem to view the development of content ecosystems simply as a means to ship their next device. If Apple is truly expecting the sales numbers of this device that Bloomberg suggests — similar to Valve’s early Index headset sales — then color me doubtful that there will be much developer interest at all in building for a stopgap device, I’d expect ports of Quest 2 content and a few shining stars from Apple-funded partners.

I don’t think this will me much of a shortcut for them.

True AR hardware is likely going to have different standards of input, different standards of interaction and a much different approach to use cases compared to a device built for the home or smartphone. Apple has already taken every available chance to entice mobile developers to embrace phone-based AR on iPhones through ARKit, a push they have seemed to back off from at recent developer-centric events. As someone who has kept a close eye on early projects, I’d say that most players in the space have been very underwhelmed by what existing platforms enable and what has been produced widely.

That’s really not great for Apple or Facebook and suggests that both of these companies are going to have to guide users and developers through use cases they design. I think there’s a convincing argument that early AR glasses applications will be dominated by first-party tech and may eschew full third-party native apps in favor of tightly controlled data integrations more similar to how Apple has approached developer integrations inside Siri.

But giving developers a platform built with Apple or Facebook’s own dominance in mind is going to be tough to sell, underscoring the fact that mobile and mobile AR are going to be platforms that will have to live alongside each other for quite a bit. There will be rich opportunities for developers to create experiences that play with 3D and space, but there are also plenty of reasons to expect they’ll be more resistant to move off of a mutually enriching mobile platform onto one where Facebook or Apple will have the pioneer’s pick of platform advantages. What’s in it for them?

Mobile’s OS-level winners captured plenty of value from top-of-funnel apps marketplaces, but the down-stream opportunities found mobile’s true prize, a vastly expanded market for digital ads. With the opportunity of a mobile do-over, expect to find pioneering tech giants pitching proprietary digital ad infrastructure for their devices. Advertising will likely be augmented reality’s greatest opportunity allowing the digital ads market to create an infinite global canvas for geo-targeted customized ad content. A boring future, yes, but a predictable one.

For Facebook, being a platform owner in the 2020s means getting to set their own limitations on use cases, not being confined by App Store regulations and designing hardware with social integrations closer to the silicon. For Apple, reinventing the mobile OS in the 2020s likely means an opportunity to more meaningfully dominate mobile advertising.

It’s a do-over to the tune of trillions in potential revenues.

What comes next

The AR/VR industry has been stuck in a cycle of seeking out saviors. Facebook has been the dearest friend to proponents after startup after startup has failed to find a speedy win. Apple’s long-awaited AR glasses are probably where most die-hards are currently placing their faith.

I don’t think there are any misgivings from Apple or Facebook in terms of what a wild opportunity this to win, it’s why they each have more people working on this than any other future-minded project. AR will probably be massive and change the web in a fundamental way, a true Web 3.0 that’s the biggest shift of the internet to date.

That’s doesn’t sound like something that will happen particularly smoothly.

I’m sure that these early devices will arrive later than we expect, do less than we expect and that things will be more and less different from the smartphone era’s mobile paradigms in ways we don’t anticipate. I’m also sure that it’s going to be tough for these companies to strong-arm themselves into a more seamless transition. This is going to be a very messy for tech platforms and is a transition that won’t happen overnight, not by a long shot.


Other things

The Loon is dead
One of tech’s stranger moonshots is dead, as Google announced this week that Loon, it’s internet balloon project is being shut down. It was an ambitious attempt to bring high-speed internet to remote corners of the world, but the team says it wasn’t sustainable to provide a high-cost service at a low price. More

Facebook Oversight Board tasked with Trump removal
I talked a couple weeks ago — what feels like a lifetime ago — about how Facebook’s temporary ban of Trump was going to be a nightmare for the company. I wasn’t sure how they’d stall for more time of a banned Trump before he made Facebook and Instagram his central platform, but they made a brilliant move, purposefully tying the case up in PR-favorable bureaucracy, tossing the case to their independent Oversight Board for their biggest case to date. More

Jack is Back
Alibaba’s head honcho is back in action. Alibaba shares jumped this week when the Chinese e-commerce giant’s billionaire CEO Jack Ma reappeared in public after more than three months after his last public appearance, something that stoked plenty of conspiracies. Where he was during all this time isn’t clear, but I sort of doubt we’ll be finding out. More

Trump pardons Anthony Levandowski
Trump is no longer President, but in one of his final acts, he surprisingly opted to grant a full pardon to one Anthony Levandowski, the former Google engineer convicted of stealing trade secrets regarding their self-driving car program. It was a surprising end to one of the more dramatic big tech lawsuits in recent years. More

Xbox raises Live prices
I’m not sure how this stacks in importance relative to what else is listed here, but I’m personally pissed that Microsoft is hiking the price of their streaming subscription Xbox Live Gold. It’s no secret that the gaming industry is embracing a subscription economy, it will be interesting to see what the divide looks like in terms of gamer dollars going towards platform owners versus studios. More

Musk offers up $100M donation to carbon capture tech
Elon Musk, who is currently the world’s richest person, tweeted out this week that he will be donating $100 million towards a contest to build the best technology for carbon capture. TechCrunch learned that this is connected to the Xprize organization. More details


Extra Things

I’m adding a section going forward to highlight some of our Extra Crunch coverage from the week, which dives a bit deeper into the money and minds of the moneymakers.

Hot IPOs hang onto gains as investors keep betting on tech
“After setting a $35 to $39 per-share IPO price range, Poshmark sold shares in its IPO at $42 apiece. Then it opened at $97.50. Such was the exuberance of the stock market regarding the used goods marketplace’s debut.
But today it’s worth a more modest $76.30 — for this piece we’re using all Yahoo Finance data, and all current prices are those from yesterday’s close ahead of the start of today’s trading — which sparked a question: How many recent tech IPOs are also down from their opening price?” More

How VCs invested in Asia and Europe in 2020
“Wrapping our look at how the venture capital asset class invested in 2020, today we’re taking a peek at Europe’s impressive year, and Asia’s slightly less invigorating set of results. (We’re speaking soon with folks who may have data on African VC activity in 2020; if those bear out, we’ll do a final entry in our series concerning the continent.)” More

Hello, Extra Crunch Community!
“We’re going to be trying out some new things around here with the Extra Crunch staff front and center, as well as turning your feedback into action more than ever. We quite literally work for you, the subscriber, and want to make sure you’re getting your money’s worth, as it were.” More
