Grateful.
I talked to @elatable, a perennial top VC on Business Insider's Seed 100. His firm, Wisdom Ventures, wrote early checks to OpenAI in 2023 and to Anthropic in 2024. He was also an angel investor in Cerebras, which soared in its IPO last week. businessinsider.com/ex-googl…

This week, @cerebras IPO'd in one of the largest technology IPOs in history. We didn't get here alone. There are many people and companies to thank. To our families. It is not easy to be married to someone trying to build a company. The hours are long and so are the years. Their patience knew no bounds. To our team. They bet big chunks of their careers on 5 guys who said we could solve a problem nobody had solved in 75 years. There were 18 months between 2017 and 2019 when we couldn't make a single chip work. We were burning $8M a month. Every six weeks we'd sit with our board and say: not yet. Not yet. Not yet. The team stayed steady. They solved problems nobody else could. When our first wafer worked in August 2019, the technology was solved. But it was still 2019. OpenAI was nascent. There was no Anthropic. AI was still a parlor trick. Then the models got good enough to be useful. In some areas, necessary. And when something becomes useful, speed is everything. Our business exploded. To our early investors - @benchmark, @FoundationCap, @EclipseVentures, @coatuemgmt, @AltimeterCap and many more - whose support never wavered through years of challenges. To TSMC, who agreed to work with us when we were a 40-person team with big ideas. To our earliest customers - Argonne, Sandia, GSK - who bet on us when the product was raw and the roadmap unproven. To Peng at G42, their Chairman, and the leadership of the UAE, who believed in us when many people were afraid. And to many others not mentioned who contributed in ways large and small. We say thank you. Today starts a new chapter for us. But it is still, just the beginning. Photo Credit: @Nasdaq / Vanja Savic

Absolutely incredible team behind this technology...
We're Optimal Intellect, a research lab from the team behind CVXPY. Today we're introducing Moreau: a GPU-native solver that's orders of magnitude faster than the best existing tools.

Jobs called computers "bicycles for the mind" -- tools we could shape to our will. But they never were. Until now. Every morning an agent preps me for my day -- calendar, news, last 24hrs of Slack -- in a personal podcast. I made it by asking. Same for hundreds of other things. Launching @dreamer in beta today. That 🧠 bicycle, finally. dreamer.com

Had a fantastic conversation with @ryanlpeterman about #Engleadership, #career growth, and what we're building at /dev/agents. We covered everything from scaling from IC to VP at Google, to my time as CTO at Stripe, to why the world needs a new operating system for AI agents. Ryan's questions really got to the heart of what makes engineering teams and products successful—especially around building teams and creating the environment where people can do their best work. One theme that kept coming up: the magic of tight feedback loops and systems thinking. Whether you're debugging code, building a team, or designing the future of human-AI interaction, the best experiences happen when you can iterate and see results immediately. Watch it inline below!
David Singleton ( @dps ) was the CTO at Stripe for 7 years before he left to start /dev/agents. Prior to Stripe, he grew from a junior engineer to a VP at Google. I recently asked him about everything he knows about career growth and being an excellent engineering leader. We discussed: • How he grew from an IC to a VP at Google • How to hire at scale without Leetcode • Writing code as a senior leader • The story behind becoming Stripe’s CTO • The top book and habit that impacted his career Where to watch: • Youtube: youtu.be/hl6Ryc_NUm8 • Spotify: open.spotify.com/show/0MX9Py… • Apple Podcasts: podcasts.apple.com/au/podcas… What’s funny is in conversation I discovered that Philip Su (from a previous episode) and David were constantly battling for the top talent in London Philip was the London site director for Meta and David was his counterpart at Google. They grew close out of mutual respect and it’s why Philip spoke highly of David’s expertise If you haven’t seen the Philip episode I also recommend that one: youtube.com/watch?v=v2JxdjTi…

Congrats @tryramp, one of two massive markups today in (my personal angel) portfolio. (The other being @AppliedInt.) I'll spare you all the story of how I know @karimatiyeh and instead refer you to this hilarious video: x.com/loganbartlett/status/1…

Today, Ramp reached a new valuation: $16 billion. A testament to saving 40,000 businesses $10 billion and 27.5 million hours.
