As a teenager, I spent most of my time building games. I was obsessed with creating worlds other people could step inside. That obsession took me through computer science in the Netherlands, computer vision for VR in Switzerland, and eventually to a small office in downtown San Francisco where four of us were building something I'd wanted to exist since I was a teenager. Today, we're announcing $59M seed and Series A backed by Lightspeed, Amplify and incredible angels. The infrastructure for real-time interactive worlds is here.
Today, we’re coming out of stealth with $59M in seed and Series A funding, led by Lightspeed, with Amplify Partners, WndrCo, Sky9, FPV, and incredible angels. For a long time, pixels have been pre-rendered and played back passively. World Models change that entirely: pixels are generated on the fly, in real time, in response to what you're doing. Every time computing has made a shift from passive to interactive, entire industries appeared that didn't exist before. We're standing in front of such moment again. Reactor is the platform for building in the World Model era: the infrastructure that lets any developer build with World Models at global scale. With only a few lines of code, and you're streaming pixels from a frontier World Model into your product, in real time, at massively. Over the last 6 months, we’ve assembled an all-star team from Apple, Meta, Google, Luma AI, Netflix, and Replicate. We're already partnering with some of the biggest companies in the world, and hundreds of developers are already building on Reactor today.

A year ago @taiuti and I started tinkering with real-time video in cafes around San Francisco. We’d worked together on Vision Pro at Apple, deep in the real-time systems that power new types of experiences and software. World models blew us away, but nobody was building infrastructure to run them interactively at scale, so we decided to become that platform. Today we’re announcing Reactor $59M to unlock a future where real-time world models are accessible to every developer.

It’s time to unveil what we’ve been working on: today, @reactorworld comes out of stealth with $59M to power the World Model era. And we’re just getting started.
Today Reactor is coming out of stealth. We’ve raised $59M in Seed and Series A funding, led by @lightspeedvp, with participation from @AmplifyPartners, @wndrco, @Sky9Capital, and @FPVventures. Reactor is the platform for building in the World Model era: the infrastructure that lets developers build with them at global scale for the first time. Stream from a frontier World Model to your app, in real time, all in under 10 lines of code. World Models represent the next major shift in AI: pixels, audio and actions are generated on the fly, in real-time, in response to user inputs, and to the environment. Every time computing has made a shift from passive to interactive, entire industries appeared that didn't exist before. We're standing in front of such moment again. Over the last 6 months, we’ve assembled an all-star team with alumni from Apple, Meta, Google, Luma AI, Netflix, and Replicate. We're already partnering with some of the biggest names and labs in the world, and hundreds of developers are already building on Reactor. The World Model era starts now.

Good team building something very exciting!
6 months ago, @taiuti and I made a bet. World models are the next platform shift, and we saw it coming. Since then, we've assembled a team from Apple, Meta, Google, Adobe & Microsoft and raised from top-tier investors. Come build with us: reactor.inc

Big update: I’m starting a new company. 6 months ago, @_bschmidtchen and I made a bet. What if entire worlds could be generated on the fly, pixel by pixel? World models are the next platform shift, and we saw it coming. Since then, we’ve: - secured major contracts across media and physical AI industries - assembled a team of 10 from Apple, Meta, Google, Adobe & Microsoft - raised from top-tier investors More details soon. We’re scaling fast, and hiring now. Come build with us: reactor.inc

When I tell you how November 2016 completely changed the center of gravity on DEI work. It was, for many leaders, instant relief that Power no longer cared about inclusion, no longer needed fairness in gender or race or culture The heel turn was pronounced. This was inevitable

Such an important topic that many of us don't think about until its too late. Love how @AlexandraMysoor and the @letalixdoit team is using AI to tackle this critical need.
The death of a family member can be both emotionally and financially challenging. In this week's Time Out @JonFortt sits down with @AlexandraMysoor - she's the CEO of @letalixdoit - a company using tech to make estate settlement easier

Violence isn't just about fists and guns; it's in the words that wound, the silence that hurts, in the policies that disenfranchise the vulnerable. #CorettaScottKing

Lifting up this message from @ArianSimone and Ayana Parsons @FearlessFund. Their words and willingness to fight is all that really needs to be said. I hope this turns into even more opportunity for them. Bring a folding chair 🪑- fearlessfreedomnow.org/ #FearlessFreedomNow
