We are excited to announce one of the biggest changes we have ever made at @b12. We started working on AI-powered websites in 2015. This was before ChatGPT, before the scaling laws, and even before OpenAI was founded. We spent the last decade building tooling, themes, and a library of components that would help us bring AI to websites. It was, at times, a glimpse into our AI future. Over the last year, coding agents have made tremendous progress, and we have had many discussions about what that means for B12. It became increasingly clear that the future of our space would be driven by agentic coding. Not only is the technology improving exponentially, but the promise of code generation also aligns well with the pain points we hear from users who want to build without constraints. So we made a hard call: we disrupted ourselves and moved beyond a framework we had spent years building. Today, we are announcing B12 3.0, powered by a new coding agent. We have been testing it over the last few weeks, and the results have been stunning. B12 3.0 has enabled users to build websites, apps, and internal tools that are richer in functionality and design. It has also doubled our purchase rate. Huge thanks to the whole team that worked so hard to bring B12 3.0 to market and to our users who have provided tremendous feedback. We are in the early innings of how agentic coding will change what we can all build. I’m excited to bring this capability to B12!

B12 is excited to be one of the first apps on ChatGPT! Across Plugins, GPTs, and now Apps, @b12 has been lucky to help millions of @OpenAI users build and grow websites with AI.

@joshwoodward @GeminiApp I'd love to see Gems expanded and a way to discover Gems made by the community.

You're a power user on @GeminiApp. What else do you want to see? Top known requests: MacOS app, Projects, and Branching Chats.

@bdistel Congrats @bdistel and the @trywindmill team on the launch!

We created AI that generates real-time lifelike video and drives cars autonomously. And yet, for decades, performance reviews have remained the most dreaded, manual, soul-sucking ritual in modern work. Until today. I’m incredibly proud (and honestly a little emotional) to announce that @trywindmill built the first AI performance review system that people actually like. No more: Employees copy-pasting a year’s worth of wins across 27 tabs Managers burning entire weekends digging through Slack & Docs HR teams playing whack-a-mole with spreadsheets and overdue forms With Windmill AI Performance Reviews, great feedback happens continuously, fairly, and effortlessly. The era of manual performance reviews is dead, forever. If you’re still stuck in manual performance review hell in 2025, life doesn’t have to be like this. Tag an HR leader at a company that deserves a better life and we’ll treat a handful of them to a Michelin-star dinner on us.

@bhalligan That sounds like Larry! :)

8. I had an investor who said to me, "Brian, money runs through startups like shit through a goose." 🪿💩

Things that surprise first time CEOs 1. It’s more stressful than they thought, particularly being responsible for a lot of employees 2. You’re the shit umbrella for all the company’s woes. 3. There’s no one to complain to (other than your cofounder) 4. If you’ve done it awhile, you’ve dealt w a big crisis or two 5. When you’re down, X and Reddit kick the shit out of you personally. 6. Even if your company isn’t 996, you are. 7. It’s not glamorous What else?

Memory can unlock how we use AI. @taranjeetio and the @mem0ai team are building the infrastructure to bring AI across applications. I was lucky enough to invest in the pre-seed. Just as inspiring as the traction is Tarajeet's journey from India to SF to build Mem0.

@AriX @ChatGPTapp go @AriX!! ❤️

So excited to join OpenAI and continue our work on Sky together with @ChatGPTapp!

Way to go Sky! In a market where great builders can do more than ever, you couldn’t ask for more talented folks than @AriX and @conradev to help shape the future of AI on your device. Thanks so much for letting me support you as an angel for the second time!

Congrats to the @Lighter_xyz community on the mainnet launch! @vnovakovski is both a brilliant and resilient founder and it is awesome to see him and Lighter thrive.

@bznotes Just sent you a DM!

@nbanta Love to try it.

I have some Sora invites. Just reply / DM if you want one :)

We just launched the B12 Agent! It helps you edit, launch, and manage your website with AI. It has already been used hundreds of thousands of times and is now available to all our users. Let us know what you think!

I distinctly remember learning about Arnav and silent speech in 2018. This team has pioneered a new way for us to communicate with computers and each other. I recently saw the product at @alterego_io's office, and it feels like magic. I'm excited for the future and thrilled to invest in this incredible team.

It's clear to see the pace of AI in our own tools. It is harder to grasp the speed of change in other domains. @joshim5 and the @chaidiscovery are quickly advancing the frontier of how we can engineer molecules.

@ammaar I would love to try it out!

We're cooking up a fresh new design for AI Studio! ✨ And we'd absolutely love your input. If want to test an early prototype and share your thoughts on a call, just drop a reply below! Your feedback will help us shape it.

@epaley Big congrats Eric!! I’m excited to see all the amazing things you do next.

My Next Chapter - Team Massachusetts I’m honored to share that Governor Healey has appointed me to be the Massachusetts Secretary of Economic Development. This is not a sentence I ever imagined I’d be writing. I’ve spent my career as an entrepreneur and venture capitalist. Although I studied Government as an undergraduate and interned long ago in Congress, I thought my career had permanently diverged into the private sector. And yet, I’ve long had a desire to serve and play a role in making a difference for my community. Accepting this appointment means stepping away from a position that, for 16 remarkable years, has felt nearly ideal. At Founder Collective, I’ve had the privilege of working alongside my closest friends and an exceptional team. Every day, I’m inspired by the brilliance and resilience of the founders we support—visionaries building technology to rethink our world. Founder Collective has become well known and respected for our mission-driven approach to venture capital, which puts founders ahead of funders and obsessively focuses on how to drive founder alignment as we partner with companies at the earliest stage. It was always my assumption that Founder Collective would be my professional home until retirement many years in the future. While I transition, I have absolute faith that Founder Collective’s vital mission will continue to thrive long beyond my time, capably driven by my phenomenal partners. My initial reaction to any career change was an emphatic 'no.' I’ve spent the last 26 years honing my craft and the past 16 years crafting a special institution. I simply have too many commitments and way too fortunate a position to walk away. But then I couldn’t sleep that night. My mind raced with the profound implications of an opportunity to make an impact on a scale I never envisioned possible. I’ve watched and admired how Secretary Hao has worked with Governor Healey to make Massachusetts a better place to do business, to live, and to innovate. I simply couldn’t say no to the call to step up to a much broader platform and help improve the community that I love. The inherent magic of startups lies in their ability to identify seemingly small, targeted products that, when skillfully designed, can scale to generate immense impact. I’m fascinated by the prospect of applying this entrepreneurial mindset to the state economy. While I have much to learn about the diverse economic pockets across our Commonwealth, my startup experience underscores the need to boldly experiment with game-changing interventions, then rigorously scale what unequivocally works. Applying this mindset to the role is wide ranging: from exploring how we can further scale our already incredible life sciences sector, to simultaneously engaging with leaders of our small towns and gateway cities to uncover the specific initiatives that will catalyze their local economic goals. It’s commonplace, even expected, to harbor cynicism toward government. I confess, I’ve shared some of that hesitation. Balancing diverse public interests is undeniably a challenging, often slow process. Yet, my initial exposure to the Healey-Driscoll Administration has been profoundly reassuring. I’ve been struck by the work ethic, dedication to integrity, and commitment to service of the people I’ve met thus far. I am inspired by the example set by our Governor and Lt. Governor, and I am eager to meet my future collaborators—those who are working hard to drive our state forward. I have now lived half my life in the Commonwealth of Massachusetts. I cannot envision a more exceptional place to raise a family, educate our children, foster intellectual exchange, and collaboratively define our forward-looking community. This dynamic state has enriched my life immeasurably, and now, it is my time to reciprocate. I am ready to play my part in designing our collective future. I’m under no illusion that this journey will be easy; we face formidable headwinds. Yet, this profound responsibility only intensifies my motivation to step up to the challenge. To my partners, our team, and the founders who work tirelessly to invent the future — I’m profoundly grateful. I have a lump in my throat knowing that I won’t be alongside all of you through all of your exciting chapters ahead. Thank you to the broader innovation ecosystem both in Massachusetts and nationally that has embraced and celebrated our unique approach to venture capital and provided an environment that makes it possible for innovators to take the risk of trying to birth dreams into reality. Secretary Hao, I’m so appreciative for your leadership and example - I know I have huge shoes to fill. I am deeply honored and grateful to Governor Healey and Lt. Governor Driscol for entrusting me with the critical mission of advancing the Commonwealth’s economic agenda. Most of all, thank you, Massachusetts, for being such an incredible home and platform to build a life. I will work my hardest to drive forward that promise to our fellow citizens.

Congrats to @circle on the IPO today! In 2013, I had the opportunity to work with Jeremy and David while the company was being incubated at @generalcatalyst. That experience taught me three things: - There are levels to entrepreneurship, and Jeremy showed what it means to operate at a different level. - I learned the value of backing great founders repeatedly. David had worked with Jeremy several times, and it felt like they’d always be building together. - Bitcoin and crypto were going to be big 🚀 Circle has become foundational internet infrastructure. I’m excited to see what’s next!

Excited for Sky to bring AI to macOS! @AriX and @conradev are amazing builders and I'm excited to back them for a second time ☁️
