Nuclear fusion conjures images of massive reactors or banks of dozens of large lasers. Avalanche co-founder and CEO Robin Langtry thinks smaller is better.
For the last several years, Langtry and his colleagues at Avalanche have been working on what’s essentially a desktop version of nuclear fusion. “We’re using the small size to learn quickly and iterate quickly,” Langtry told TechCrunch.
Fusion power promises to supply the world with large amounts of clean heat and electricity, if researchers and engineers can solve some vexing challenges. At its core, fusion power seeks to harness the power of the Sun. To do that, fusion startups must figure out how to heat and compress plasma for long enough that atoms inside the mix fuse, releasing energy in the process.
Fusion is a famously unforgiving industry. The physics is challenging, the materials science is cutting edge, and the power requirements can be gargantuan. Parts need to be machined with precision, and the scale is usually so large as to obviate rapid fire experimentation.
Some companies like Commonwealth Fusion Systems (CFS) are using large magnets to contain the plasma in a doughnut-like tokamak, others are compressing fuel pellets by shooting them with powerful lasers. Avalanche, though, uses electric current at extremely high voltages to draw plasma particles into an orbit around an electrode. (It also uses some magnets to keep things orderly, though they’re not nearly as powerful as a tokamak’s.) As the orbit tightens and the plasmas speed up, the particles begin to smash into each other and fuse.
The approach has won over some investors. Avalanche recently added another $29 million in an investment round led by R.A. Capital Management with participation from 8090 Ventures, Congruent Ventures, Founders Fund, Lowercarbon Capital, Overlay Capital, and Toyota Ventures. To date, the company has raised $80 million from investors, a relatively small amount in the fusion world. Other companies have raised several hundred to a few billion dollars.
Space-based inspiration
Langtry’s time at the Jeff Bezos-backed space tech company Blue Origin influenced how Avalanche is tackling the problem.

“We’ve figured out that using this sort of SpaceX ‘new space’ approach is that you can iterate really quickly, you can learn really quickly, and you can solve some of these challenges.” said Langtry, who worked with co-founder Brian Riordan at Blue Origin.
Going smaller allowed Avalanche to speed up. The company has been testing changes to its devices “sometimes twice a week,” something that would be challenging and costly with a large device.
Currently, Avalanche’s reactor is only nine centimeters in diameter, though Langtry said a new version grow to 25 centimeters and is expected to produce about 1 megawatt. That, he said, “is going to give us a significant bump in confinement time, and that’s how we’re actually going to get plasmas that have a chance of being Q>1.” (In fusion, Q refers to the ratio of power in to power out. When it’s greater than one, the fusion device is said to be past the breakeven point.)
Those experiments will be carried out at Avalanche’s FusionWERX, a commercial testing facility the company also rents out to competitors. By 2027, the site will be licensed to handle tritium, an isotope of hydrogen that’s used as fuel and is crucial to many fusion startup’s plans for producing power for the grid.
Langtry wouldn’t commit to a date when he hopes Avalanche will be able to generate more power than its fusion devices consume, a key milestone in the industry. But he’s thinks the company is on a similar timeline as competitors like CFS and the Sam Altman-backed Helion. “I think there’s going to be a lot of really exciting things happening in fusion in 2027 to 2029,” he said.

![Sam Altman’s project World looks to scale its human verification empire. First stop: Tinder. | TechCrunch
At a trendy venue near the San Francisco pier, Sam Altman’s verification project World celebrated its next evolution and rapid expansion of its ambitions. And it’s starting with Tinder.
Tools for Humanity (TFH), the company behind the World project, announced Friday plans to integrate its verification tech into dating apps, event and concert ticketing systems, business organizations, email, and other arenas of public life.
“The world is getting close to very powerful AI, and this is doing a lot of wonderful things,” said Altman, speaking before a packed crowd at The Midway. “We are also heading to a world now where there’s going to be more stuff generated by AI than by humans,” he added. “I’m sure many of you [have had moments] where you’re like, ‘Am I interacting with an AI or a person, or how much of each, and how do I know?”
World (formerly Worldcoin) distinguishes itself from many of its ID verification peers by offering the ability to verify that a real, living human is using a digital service while still protecting that person’s anonymity. There is some complex cryptographic alchemy behind this (something called “zero-knowledge proof-based authentication”). The upshot: The company is creating what it calls “proof of human” tools, which are mechanisms that can verify human activity in a world rife with AI agents and bots.
Its chief tool for verification is a spherical digital reader called the Orb that scans a user’s eyes, converting their iris into a unique and anonymous cryptographic identifier (known as a verified World ID). This can then be used to access World’s services, although users can also access World’s app without one.
Altman kept his remarks brief on Friday (TFH’s co-founder and CEO, Alex Blania, was absent due to a last-minute hand surgery, Altman said). He then turned much of the presentation over to World’s chief product officer, Tiago Sada, and his team.
Sada explained that World was launching the newest version of its app (the last version was launched at an event in December), along with a plethora of new integrations for its technology.
World has been preparing, for some time, to deploy a verification service for dating apps — most notably, Tinder. Last year, Tinder launched a World ID pilot program in Japan. That pilot was apparently a success because World announced that Tinder would be launching its verification integration in global markets —including the U.S. The program integrates a World ID emblem into the profiles of users who have gone through its verification processes, thus authenticating them as a real person.

World is also courting the entertainment industry by launching a new feature called Concert Kit, where musical artists can reserve a certain number of concert tickets for World ID-verified humans. This is designed to ensure that fans are safe from scalpers who often use automated ticket-buying bots to scarf up seats. Concert Kit is compatible with major ticketing systems, including Ticketmaster and Eventbrite, and the company is promoting it via partnerships with 30 Seconds to Mars and Bruno Mars — both of whom plan to use it for their upcoming tours.
The event was full of many other announcements, including some aimed at businesses. A Zoom/World ID verification integration seeks to battle a supposed deepfake threat to business calls, and a Docusign partnership is designed to ensure signatures come from authentic users.
The company is also working on a number of features in anticipation of the Wild West of the agentic web, including one called “agent delegation,” in which a person can delegate their World ID to an agent to carry out online activities on their behalf. A partnership with authentication firm Okta has also created a system (currently in beta) that verifies that an agent is acting on behalf of a human. The system is set up so that a World ID can be tied to a specific agent and then, when the agent goes out into the web to operate on that person’s behalf, websites will know a verified person is behind the behavior, said Okta’s chief product officer, Gareth Davies, at the event.
So far, it’s been difficult for World to scale, due largely to the verification process itself. For much of the company’s history, to get its gold standard, you had to travel to one of its offices and have your eyeballs scanned by an Orb — a fairly inconvenient (not to mention weird) experience.
Image Credits:World
However, World has continually made moves to increase the ease and incentive structure for verification. In the past, it offered its crypto asset, Worldcoin, to some members who signed up and has distributed its Orbs into big retail chains so that users can verify themselves while they’re out shopping or getting a coffee. Now the company is announcing that it is significantly expanding its Orb saturation in New York, Los Angeles, and San Francisco. The company also promoted a service where interested users could have World bring an Orb to their location for remote verification.
In a conversation with TechCrunch, Sada also shared that World has attempted to solve the scaling problem by creating different tiers of verification. The highest tier is Orb verification, but below that, World has previously offered a mid-level tier, which uses an anonymized scan of an official government ID via the card’s NFC chip.
The company also introduced a low-level tier, or what Sada called “low friction”— meaning low effort, I guess, but also “low security” — which involves merely taking a selfie.
Selfie Check, which Sada’s team presented during the event, is designed to maintain user privacy.
“Selfie is private by design,” said Daniel Shorr, one of TFH’s executives, during the presentation. “That means that we maximize the local processing that’s happening on your device, on your phone, which means that your images are yours.”
Selfie verification obviously isn’t new, and fraudsters have long managed to spoof it. “Obviously, we do our best, and it’s like one of the best systems that you’ll see for this. But it has limits,” Sada told TechCrunch. Developers looking to integrate World’s services can choose from the three different verification tiers depending on the level of security that’s important to them, he noted.
