Great to see Ricursive's own @carolinetrippel give an invited talk at #ICLAD2026 🎙️. Her research tackles hardware bottlenecks head on, using AI + Formal Methods to turn 1-hr timeouts into sub 15-sec checks. Proud to have Caroline guiding Ricursive's DV direction.

3 packed days at @DACconference! The energy at Booth #1049 was unmatched. Huge thanks to everyone who stopped by to learn more about Ricursive, brainstorm on accelerating chip design, or just pick up some cool swag. Until next year!

Proud to join @Microsoft, @nvidia, @a16z, @PalantirTech, and 230+ tech leaders as a signatory supporting Open Weights and American AI Leadership. An open, secure ecosystem is essential to accelerating hardware-software-model co-design and democratizing custom silicon.
Since launching last week, more than 230 companies and organizations from across the tech sector have signed the "Open Weights and American AI Leadership" open letter. We want to thank these partners for standing up and publicly supporting broader access to AI innovation. A special thanks to @nvidia, @a16z, and @PalantirTech for working with @Microsoft on this effort. These signatories understand that America’s AI leadership will not depend on the success of our frontier models alone, but on our ability to build a strong, secure, and open ecosystem that diffuses AI into every sector. We look forward to continuing to work with our partners and with policymakers to build that open ecosystem in a way that benefits American businesses, empowers American workers, and strengthens the American economy.

"AI inference demand is expected to grow 10,000x over the next 5 years." Yesterday at @DACconference, @annadgoldie took the stage to share how we break today's deadlock between model and hardware. That's what we're doing at Ricursive, using our very own model. 📍 Stop by Booth #1049 to say hi.

The event was scheduled to end at 8pm. The conversations ran well past it. Ricursive's "Chips & Pints" outgrew the room we booked, so we took over the brewery. Thanks to everyone who battled the Long Beach heat after day 1 of @DACconference to spend Monday evening with us 🍻.

Our co-founder @Azaliamirh met with @TIME at last week's @RaiseSummit to discuss Ricursive. We're using AI to revolutionize chip design. And instead of years, it will take days.
Chip design takes years. At @RaiseSummit, Ricursive says AI can dramatically speed up the process—and that better chips will in turn enable better AI models, creating a recursive cycle of improvement.

Day 2 at @icmlconf called for a change in altitude. Rooftop dinner in Itaewon with @ElorianAI, @strikervp, and @DeltaCommunityX: skyline views, a DJ set, and the kind of unhurried conversations that don't happen on the conference floor.

Some discoveries change your research agenda. Others, your wardrobe. Spectrum at @icmlconf with MoE Capital, @GreylockVC, @hashed_official, and @BainCapVC: Korean color analysis, fresh salt bread, and conversations on AI for science. Came for the colors, stayed for the conversations.

Our own @DZhang50 took the stage at @500GlobalVC's AI Super Night on the sidelines of @icmlconf to talk about where AI research goes next, in a venue best described as a whisky speakeasy hidden inside a secret garden.

You can tell a lot about a research community by who still shows up on the last day. Closing out @icmlconf with 1943, @SophontAI, GMI Cloud, and @ZZZZZPotentials for a farewell lunch @InterConHotels COEX: a full room trading ideas. 💡🥂 Thanks for joining us! 🫶

Transforming chip development requires not only the best researchers, but also the dedicated compute and unwavering focus that pushing the boundaries of AI demands. That's why we started Ricursive. Grateful to be featured in @Bloomberg by @byJuliaLove alongside other daring founders. bloomberg.com/news/articles/…

Great to see our vision of end-to-end chip design featured in @eetimes. Thanks to @sallywf for the excellent profile. Traditional chip design costs too much time and money. By changing that, we're enabling truly transformative applications of AI that were previously impossible. eetimes.com/startup-ricursiv…

The task: rapidly design highly performant chips. The vision: serve intelligence at a price and capability impossible to match. Our co-founder and CEO @annadgoldie sat down with @FounderCoHo to break down the recursive self-improvement loop at the heart of Ricursive's work. The task and vision are ambitious, but so are we.

$4B valuation. $300M Series A. The bet? AI that designs its own chips. 👇 Anna Goldie (@annadgoldie), Founder & CEO of @RicursiveAI and co-creator of AlphaChip, is building toward a recursive loop: AI designs better chips → better chips train better AI. Today, frontier chips can take years and hundreds of millions to build. Ricursive’s Vision : ▸ Speed up chip design, ▸Make custom silicon more accessible, ▸Eventually co-evolve AI with the hardware that powers it. AI is no longer just running on chips. It’s starting to redesign them.

Chips are the fuel for AI. By using AI to design, optimize, and automate chip design, we can close the recursive self-improving loop between AI and its physical substrate. Our co-founders @annadgoldie and @Azaliamirh took the stage at @sequoia AI Ascent 2026 to share more about Ricursive’s vision to accelerate and democratize chip design. Proud of the progress our world-class team has already made. And we’re just getting started!
