Today we're announcing over $9B in capital for a new family of funds — our largest raise in 25 years.
AI is rewriting the rules. We're backing the founders building what comes next.
Finances shouldn’t be fragmented.
We're excited to double down in @tryramp for their recent $750M Series F, bringing their total valuation to $44B.

As agents take on more responsibility, reliability becomes critical.
@raindrop_ai is working to prevent that.
They just released Raindrop 2.0 to help build fixes out of failures. Their “self-healing” agent loop evaluates multiple angles of the problem, with the goal of preventing it from happening again.
We first invested in Raindrop in 2025, and co-founders @alexisgauba, @benhylak, and @snarkyzk have continued to innovate with agents in production.
As more businesses turn to agents, tech like this that can help improve quality and durability becomes indispensable in the stack.
today, we’re excited to announce raindrop 2.0: self-healing agents.
we now train custom models that autonomously detect hidden issues with your agent.
i could tell you all about it, but wouldn’t you rather hear it from someone… else?
The race to unlock fusion power is heating up.
@Helion_Energy is a fusion power company with a mission of producing a clean, zero-carbon electricity source. Two years ago, they launched their 7th-generation prototype, Polaris, and are now building their first fusion power plant in Washington.
We believe their progress in fusion power is remarkable, and that’s why we participated in their recent $465M Series G. This latest round brings Helion’s total valuation to $1.5B, reaching $15.5B post-money.
We believe a clean, reliable energy source is on the horizon, and that Helion is positioned to help lead the charge.

We’re tripling down on our investment in @suno.
After leading Suno’s Series B in 2024, we're proud to invest again in their $400M Series D, which brings the company’s post-money valuation to $5.4B.
Suno is a company that allows anyone, regardless of skill level, to create music. The AI platform was built to increase access to music creation. Now, videos using songs made with Suno are going viral.
AI has the potential to make a major impact on accessibility to the arts. Suno is a great example of this, offering users a platform to express themselves through music.
Congratulations to the Suno team on their growth! We believe the platform has big potential, and are looking forward to seeing how Suno will continue to progress.

AI has gone from generating words to generating worlds.
@reactorworld is a real-time generative video platform built for developers. Their infrastructure layer enables users to work with scaling and production in mind. Co-founders @taiuti and @_bschmidtchen previously worked as technical leads on the Apple Vision Pro. Now, they're bringing their world model expertise to Reactor.
We’re thrilled to announce that we led their $59M Series A as they emerge from stealth, and we can’t wait to see how they continue building.
We believe world models have the potential to be the next wave of AI, as they let people step into and experience their creations.
Reactor is working to fortify the software foundation to keep up.
