At the start of this year, @joshim5 told me 2026 would be the "year of deployment" for @chaidiscovery That wasn't just an aspiration — Chai has now signed its 6th pharma deal in the past 9 months: Lilly Pfizer Novartis argenx BMS and now with GSK: endpoints.news/chai-discover…

Thrilled to announce our $400M Series C led by @IndexVentures, with @kleinerperkins, @sequoia, @_DimensionCap and others. Great to speak to @m_delamerced @nytimes about how drug discovery using AI is moving from a promise to actual deployment.

Congrats to @joshim5 @jackdent and @chaidiscovery on Series C and for continuing to push the frontier of AI in drug discovery toward deployment at scale! Excited to continue to collaborate @MenloVentures
Tomorrow's medicines should be designed with the precision and scale of modern engineering. I'm thrilled that @ChaiDiscovery has raised a $400M Series C at a $3.8B valuation from @IndexVentures @KleinerPerkins @Sequoia @_DimensionCap to accelerate progress towards that goal.

Congrats to @chaidiscovery and @Novartis teams for the new collaboration and to see deployment of Chai-3 at scale!
I'm delighted to announce a new collaboration between @ChaiDiscovery & @Novartis. It's been a pleasure working together over the past year, and we're excited to scale our collaboration to support broader deployment of Chai-3 across multiple therapeutic programs.

Neural networks might speak English, but they think in shapes. Understanding their rich *neural geometry* is key to understanding how they work – and to debugging and controlling them with precision. Starting today, we’re releasing a series of posts on this research agenda. 🧵

The rise of Anthropic in our data this year was one of the most notable headlines, increasing from 12% market share the first year we ran the survey to 40% this year, and an even more eye-opening 54% in code The momentum is more than a vibe shift (though plenty of that too, especially on the TL as of late), but evidence of sustained value accrual to the frontier in LLM markets -- with Anthropic at the lead

We’re thrilled to announce our collaboration with @EliLillyandCo. We’ll be deploying Chai’s AI models to power biologics discovery across a broad set of drug programs at Lilly. This is a major step forward in pharma’s adoption of AI-native R&D.

Menlo Ventures is announcing a $16 million seed investment in @AuroraTher! More than 350 million people worldwide live with over 7,000 rare diseases. Aurora is building the first platform for treating rare genetic mutations that have historically been impossible to address at scale. We’re proud to have incubated Aurora and we’re excited about the team being built. Congratulations to Professors Jennifer Doudna and @UrnovFyodor, and Edward Kaye.

Congrats to @deedydas on your well deserved promotion! You've been a fantastic partner to all of us @MenloVentures on all things AI! More great things ahead!
Big personal news! After a remarkable 18mos at Menlo Ventures, I'm excited to announce that perhaps against better judgement, they have decided to make me a Partner at the firm. Wild that just 6yrs ago, I'd be up at 2am debugging Google Search. A little bit about my journey:

.@grgyap, Partner at @MenloVentures, shares how generative AI is profoundly changing drug discovery: "It offers you the potential to create new molecules that have never been thought of by humans before." "Now you have an opportunity to... make a drug by seeing inside the lock, understanding the structure of that lock, and trying to make a key that actually fits that space."
