Kevin Weil 🇺🇸

@JoshuaKushner Congrats my friend, and to the whole Thrive team. Love this move.

Today we announce Thrive Eternal, a permanent capital holding company that will be concentrated in a small number of assets that we can own and steward over many decades. Across Thrive Capital and Thrive Holdings, we are building and investing through a moment of exponential change; backing emerging technologies, the infrastructure that powers them, and the businesses they can transform. Increasingly, we see a fourth category. These are assets with qualities that cannot be replicated by technology. Iconic franchises and cultural institutions rooted in tradition, identity, and shared experience. In a world shaped by abundant intelligence where creation scales and distribution fragments, we believe they will matter even more. Thrive Eternal is built on the belief that the most enduring of these assets share common characteristics: they benefit from long-term stewardship, they compound through cultural resonance, and they are enhanced by technology rather than displaced by it. Our work at Thrive has always been informed and inspired by a deep appreciation for product, brand, and the ways in which consumers form lasting relationships with the things they love. We have been building towards this for a long time. Our first partnership is expected to be with the San Francisco Giants - an institution built on more than a century of shared identity and community, and among the most iconic sports franchises in America. We have reached an agreement, subject to league approval, to acquire an ownership stake. We feel privileged by the opportunity to be long-term partners to the Giants.

@kate_rouch Amazing work friend!

Last night, ChatGPT’s first-ever brand campaign won AdAge Campaign of the Year. The judges called it “a remarkable humanizing of the software”. Not just a tool for answers, but “a way of living life a little better.” “The craft was stunning.” “To bring that much humanity to AI was impressive.” Cynicism wins on Twitter. Our job is to humanize AI for everyone else. Mad respect to the tiny, kind team that dreamed it up.

@MillionInt that's good but we had better strawjerry images on oai slack, please incorporate some

@BigTechAlert @dyett damn straight

🆕 @kevinweil has started following @dyett

@joyjiao12 The feeling is mutual! I can't wait to see where you take GPT-Rosalind and more—such important work.

@kevinweil Kevin, I am so grateful for all the things I've learned from you. Was just thinking about our first "on site" where it was just 7 people in a mtg room. I am simultaneously sad but also so impressed by what you've built in a short time! Best of luck on your next adventure!

Today is my last day at OpenAI, as OpenAI for Science is being decentralized into other research teams. It’s been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science. Accelerating science will be one of the most stunningly positive outcomes of our push to AGI, and I’m rooting for @sama @markchen90 @fidjissimo @gdb @merettm and the whole team!

@iansilber Feeling is mutual! Let's work together again :)

@kevinweil thank you for everything man, learned so much from you!

@DeryaTR_ You're an inspiration, Derya. Please keep pushing for AI in science!

Kevin had been leading Science at OpenAI. I had the privilege and pleasure of knowing and interacting with him as a friend. I am also honored to have been a co-author of the first OpenAI science vision paper that he organized. Thank you, Kevin. 🙏 arxiv.org/abs/2511.16072

@dens Been too long since we caught up!

@kevinweil Legend. Can't imagine what you're onto next. (hope you're well!)

@wickman We'll have to find workplace n+1 together :)

@kevinweil goodbye from the thunderdome 😭

@LiamFedus Thanks Liam! Inspired by the work you're doing now too :)

@kevinweil Kevin, it was great working with you while I was there, and I'm excited to see what you do next!

@michpokrass Me too! Also I will forever have your tweet framed :) Loved working together.

@kevinweil sad to see you go!! will always remember 12 days fondly 🙂

@RonConway @ericabrescia Thinking good thoughts for you and your family Ron 🙏🙏

I want to share some difficult news. I was recently diagnosed with a rare form of cancer and I want you to hear it directly from me. Treatment is starting immediately and will include multiple strategies over the course of about a year. While I will be stepping back from some of my usual activities, I will continue to support SV Angel founders, who I love with a passion. SV Angel remains unchanged. Topher has made all of our investment decisions for the better part of the last decade, and Ronny joined as Managing Partner in 2024. They bring experience from nearly every major technology cycle in Silicon Valley and are now focused on partnering with founders building the future of AI. SV Angel has a deep, experienced team that remains fully focused on supporting exceptional founders. With a more focused and balanced schedule, I can prioritize treatments while helping SV Angel founders at inflection points like we always do! I’ve chosen not to share the specific type of cancer since I don't want speculation about my prognosis. I appreciate your understanding and respect for this. I am optimistic about my prognosis. I am fortunate to have the best/amazing team of UCSF doctors in San Francisco, and as you know, I never back down from a fight. Thank you for your support, it means a great deal to me.

@_dmca Likewise! I only wish we'd gotten to overlap more.

@kevinweil it was great working with you, kevin. thanks for all you've done for openai and science.

@timzaman Love it! I've run that race before, I even won it once when no one who's actually fast showed up 😅 Happy to go for a run together one day!

@kevinweil Sad to hear Kevin! But also happy you'll have more time for kids and.. the Woodside Crossover ultras today? insidetrail.com/calendar/woods…

@reah_ai Likewise my friend, it was fun to do together!

@kevinweil thanks for all your contributions kw! loved learning from you and seeing you build parts of the rocket ship mid flight. excited to see what you do next 🚀

@dlevine815 Thank you. I loved working together and hope we get to again—if nothing else I need revenge at ping pong :)

@kevinweil @kevinweil thank you for everything you’ve done for OpenAI. I’ve learned so much working with you and can’t wait to see what’s next!

@vicapow Likewise my friend. Thanks for taking a bet on me and OpenAI!

@kevinweil @kevinweil it’s been an incredible experience to get to work with someone as talented as yourself. 🫡 really going to miss working together.

@nickaturley Thanks man, loved working together and learning from you. Keep making ChatGPT awesome, I'm a DAU :)

@kevinweil @kevinweil It was an honor to get to learn from you, build chatgpt together, and be inspired by your work on science. Really going to miss you!!
