Stoke Space wants to take reusable rockets to new heights with $9M seed

Published

on

Many launch providers think reusability is the best way to lower the cost and delay involved in getting to space. SpaceX and Rocket Lab have shown reusable first stages, which take a payload to the edge of space — and now Stoke Space Technologies says it is making a reusable second stage, which will take that payload to orbit and beyond, and has raised a $9.1 million seed round to realize it.

Designing a first stage that can return to Earth safely is no small task, but the fact that it only reaches a certain height and speed, and doesn’t actually climb into orbit at an even higher velocity, means that it is simpler to try. The second stage takes over when the first is spent, accelerating and guiding the payload to its destination orbit, which generally means it will have traveled a lot farther and will be going a lot faster when it tries to come back down.

Stoke thinks that it’s not just possible to create a second stage that’s reusable, but crucial to building the low-cost space economy that will enable decades of growth in the industry. The team previously worked on the New Glenn and New Shepard vehicles and engines at Blue Origin, the Merlin 1C for the Falcon 9 at SpaceX and others.

“Our design philosophy is to design hardware that not only can be reused, but is operationally reusable. That means fast turnaround times with low refurbishment effort. Reusability of that type has to be designed in from the beginning,” said Andy Lapsa, co-founder and CEO of Stoke.

Beyond the fact that the vehicle will employ a ballistic reentry and powered landing, Stoke did not comment on the engineering or method by which it would accomplish the Herculean feat of bringing down a few tons of precision equipment safely from 400 kilometers up and traveling some 28,000 km/h. (Though Lapsa did mention to GeekWire that a “good, high-performing stable injector” is the core of their engine and therefore of the system around it.)

At speeds like that reentry can be deadly, so one hopes they save a little fuel not just for landing but for deceleration. That would increase the mass and complexity of the vehicle before payload, lowering its carrying capacity.

“It’s true that any reusable system will be inherently more complex than its expendable counterpart,” Lapsa said. “However, when one optimizes on mission cost and availability, that complexity is well worth it.”

As other launch companies have pointed out, you burn up a lot of money on reentry, but so far the safest move has been to keep the first stage alive. The second stage is by no means cheap, and any company would prefer to recycle it as well — and indeed it could lower the cost of launch enormously if they did so successfully.

The promise Stoke makes is not just to bring the upper stage home, but to bring it home and have it ready for reuse just a day later. “All launch hardware is reused time after time with aircraft-like regularity — zero refurbishment with 24-hour turnaround,” claims Lapsa.

Considering the amount of wear and tear a rocket goes through in ascent and landing, “zero refurbishment” may sound to many like an impossible dream. SpaceX’s reusable first stages can be turned around pretty quickly, but they can’t just fuel them up where they landed and press the button again.

Not only that, but Stoke aims to provide reusable-rocket service beyond low-Earth orbit, where the majority of small, lower-cost satellites go. Geosynchronous orbit and translunar or interplanetary trajectories are also planned.

“Missions to GTO, GEO direct, TLI and earth escape will initially be done with partially reusable or expendable vehicles, depending on mission requirements, however those vehicles will be the same ones that may have been used on previous fully reusable missions to LEO. The design is extensible to full reuse for these missions (and/or extraplanetary landers) in future variants,” said Lapsa.

These are ambitious claims — even, given the state of rocketry right now, ones people may with good reason call unrealistic. But the industry has advanced more quickly than many would have predicted a decade ago and seemingly unrealistic ambition drove those changes as well.

The $9.1 million seed round raised by Stoke will enable it to meet the next few milestones, but anyone who follows the industry will know that far more cash will be needed to cover the cost of development and testing in time.

The round was led by NFX and MaC Ventures, along with YC, Seven Seven Six (Alexis Ohanian), Liquid2 (Joe Montana), Trevor Blackwell, Kyle Vogt and Charlie Songhurst, among others.

Vietnamese electric motorbike startup Dat Bike raises $2.6M led by Jungle Ventures

Dat Bike, a Vietnamese startup with ambitions to become the top electric motorbike company in Southeast Asia, has raised $2.6 million in pre-Series A funding led by Jungle Ventures. Made in Vietnam with mostly domestic parts, Dat Bike’s selling point is its ability to compete with gas motorbikes in terms of pricing and performance. Its new funding is the first time Jungle Ventures has invested in the mobility sector and included participation from Wavemaker Partners, Hustle Fund and iSeed Ventures.

Founder and chief executive officer Son Nguyen began learning how to build bikes from scrap parts while working as a software engineer in Silicon Valley. In 2018, he moved back to Vietnam and launched Dat Bike. More than 80% of households in Indonesia, Malaysia, Thailand and Vietnam own two-wheeled vehicles, but the majority are fueled by gas. Nguyen told TechCrunch that many people want to switch to electric motorbikes, but a major obstacle is performance.

Nguyen said that Dat Bike offers three times the performance (5 kW versus 1.5 kW) and 2 times the range (100 km versus 50 km) of most electric motorbikes in the market, at the same price point. The company’s flagship motorbike, called Weaver, was created to compete against gas motorbikes. It seats two people, which Nguyen noted is an important selling point in Southeast Asian countries, and has a 5000W motor that accelerates from 0 to 50 km per hour in three seconds. The Weaver can be fully charged at a standard electric outlet in about three hours, and reach up to 100 km on one charge (the motorbike’s next iteration will go up to 200 km on one charge).

Dat Bike’s opened its first physical store in Ho Chi Minh City last December. Nguyen said the company “has shipped a few hundred motorbikes so far and still have a backlog of orders.” He added that it saw a 35% month-over-month growth in new orders after the Ho Chi Minh City store opened.

At 39.9 million dong, or about $1,700 USD, Weaver’s pricing is also comparable to the median price of gas motorbikes. Dat Bike partners with banks and financial institutions to offer consumers twelve-month payment plans with no interest.

“These guys are competing with each other to put the emerging middle class of Vietnam on the digital financial market for the first time ever and as a result, we get a very favorable rate,” he said.

While Vietnam’s government hasn’t implemented subsidies for electric motorbikes yet, the Ministry of Transportation has proposed new regulations mandating electric infrastructure at parking lots and bike stations, which Nguyen said will increase the adoption of electric vehicles. Other Vietnamese companies making electric two-wheeled vehicles include VinFast and PEGA.

One of Dat Bike’s advantages is that its bikes are developed in house, with locally-sourced parts. Nguyen said the benefits of manufacturing in Vietnam, instead of sourcing from China and other countries, include streamlined logistics and a more efficient supply chain, since most of Dat Bike’s suppliers are also domestic.

“There are also huge tax advantages for being local, as import tax for bikes is 45% and for bike parts ranging from 15% to 30%,” said Nguyen. “Trade within Southeast Asia is tariff-free though, which means that we have a competitive advantage to expand to the region, compare to foreign imported bikes.”

Dat Bike plans to expand by building its supply chain in Southeast Asia over the next two to three years, with the help of investors like Jungle Ventures.

In a statement, Jungle Ventures founding partner Amit Anand said, “The $25 billion two-wheeler industry in Southeast Asia in particular is ripe for reaping benefits of new developments in electric vehicles and automation. We believe that Dat Bike will lead this charge and create a new benchmark not just in the region but potentially globally for what the next generation of two-wheeler electric vehicles will look and perform like.”

Binance Labs leads $1.6M seed round in DeFi startup MOUND, the developer of Pancake Bunny

Published

on

Decentralized finance startup MOUND, known for its yield farming aggregator Pancake Bunny, has raised $1.6 million in seed funding led by Binance Labs. Other participants included IDEO CoLab, SparkLabs Korea and Handshake co-founder Andrew Lee.

Built on Binance Smart Chain, a blockchain for developing high-performance DeFi apps, MOUND says Pancake Bunny now has over 30,000 daily average users, and has accumulated more than $2.1 billion in total value locked (TVL) since its launch in December 2020.

The new funding will be used to expand Pancake Bunny and develop new products. MOUND recently launched Smart Vaults and plans to unveil Cross-Chain Collateralization in about a month, bringing the startup closer to its goal of covering a wide range of DeFi use cases, including farming, lending and swapping.

Smart Vaults are for farming single asset yields on leveraged lending products. It also automatically checks if the cost of leveraging may be more than anticipated returns and can actively lend assets for MOUND’s cross-chain farming.

Cross-Chain Collateralization is cross-chain yield farming that lets users keep original assets on their native blockchain instead of relying on a bridge token. The user’s original assets serve as collateral when the Bunny protocol borrows assets on the Binance Smart Chain for yield farming. This allows users to keep assets on native blockchains while giving them liquidity to generate returns on the Binance Smart Chain.

In statement, Wei Zhou, Binance chief financial officer, and head of Binance Labs and M&A’s, said “Pancake Bunny’s growth and MOUND’s commitent to execution are impressive. Team MOUND’s expertise in live product design and servie was a key factor in our decision to invest. We look forward to expanding the horizons of Defi together with MOUND.”

Battery Resourcers raises $20M to commercialize its recycling-plus-manufacturing operations

Published

on

As a greater share of the transportation market becomes electrified, companies have started to grapple with how to dispose of the thousands of tons of used electric vehicle batteries that are expected to come off the roads by the end of the decade.

Battery Resourcers proposes a seemingly simple solution: recycle them. But the company doesn’t stop there. It’s engineered a “closed loop” process to turn that recycled material into nickel-manganese-cobalt cathodes to sell back to battery manufacturers. It is also developing a process to recover and purify graphite, a material used in anodes, to battery-grade.

Battery Resourcers’ business model has attracted another round of investor attention, this time with a $20 million Series B equity round led by Orbia Ventures, with injections from At One Ventures, TDK Ventures, TRUMPF Venture, Doral Energy-Tech Ventures and InMotion Ventures. Battery Resourcers CEO Mike O’Kronley declined to disclose the company’s new valuation.

The cathode and anode, along with the electrolyzer, are major components of battery architecture, and O’Kronley told TechCrunch it is this recycling-plus-manufacturing process that distinguishes the company from other recyclers.

“When we say that we’re on the verge of revolutionizing this industry, what we are doing is we are making the cathode active material — we’re not just recovering the metals that are in the battery, which a lot of other recyclers are doing,” he said. “We’re recovering those materials, and formulating brand new cathode active material, and also recovering and purifying the graphite active material. So those two active materials will be sold to a battery manufacturer and go right back into the new battery.”

“Other recycling companies, they’re focused on recovering just the metals that are in [batteries]: there’s copper, there’s aluminum, there’s nickel, there’s cobalt. They’re focused on recovering those metals and selling them back as commodities into whatever industry needs those metals,” he added. “And they may or may not go back into a battery.”

The company says its approach could reduce the battery industry’s reliance on mined metals — a reliance that’s only anticipated to grow in the coming decades. A study published last December found that demand for cobalt could increase by a factor of 17 and nickel by a factor of 28, depending on the size of EV uptake and advances in battery chemistries.

Thus far, the company’s been operating a demonstration-scale facility in Worcester, Massachusetts, and has expanded into a facility in Novi, Michigan, where it does analytical testing and material characterization. Between the two sites, the company can make around 15 tons of cathode materials a year. This latest funding round will help facilitate the development of a commercial-scale facility, which Battery Resourcers said in a statement will boost its capacity to process 10,000 tons of batteries per year, or batteries from around 20,000 EVs.

Another major piece of its proprietary recycling process is the ability to take in both old and new EV batteries, process them and formulate the newest kind of cathodes used in today’s batteries. “So they can take in 10-year-old batteries from a Chevy Volt and reformulate the metals to make the high-Ni cathode active materials in use today,” a company spokesman explained to TechCrunch.

Battery Resourcers is already receiving inquiries from automakers and consumer electronics companies, O’Kronley said, though he did not provide additional details. But InMotion Ventures, the venture capital arm of Jaguar Land Rover, said in a statement its participation in the round as a “significant investment.”

“[Battery Resourcers’] proprietary end-to-end recycling process supports Jaguar Land Rover’s journey to become a net zero carbon business by 2039,” InMotion managing director Sebastian Peck said.

Battery Resourcers was founded in 2015 after being spun out from Massachusetts’ Worcester Polytechnic Institute. The company has previously received support from the National Science Foundation and the U.S. Advanced Battery Consortium, a collaboration between General Motors, Ford Motor Company and Fiat Chrysler Automobiles.
