I’m excited to announce Pensieve's collaboration with Anthropic! Pensieve TA has been helping instructors at top higher ed institutions like Columbia University, University of California, Berkeley, and Harvey Mudd College by reducing grading time and providing personalized tutoring to students.

At the start of the year, Martin (YC S23)'s annual revenue was $100k. Half a year later, we're at $100k in monthly revenue, growing 65% every month. 🤯
And we're still only 2 people. There's not enough time to finish the 101 things that need to get done, so we're looking to bring on our first founding engineer.

I’m sure you’ve heard the cliche. But it’s hard to actually find like-minded people. That’s exactly why we started AI Entrepreneurs at Berkeley
Here’s what Berkeley’s premier AI incubator is about:
- Traction over intention. - Creating space for founders to thrive. - Meeting phenomenal operators & building solutions that matter
Here’s how we've been doing that:
- $100M+ in valuation. $20M+ raised. 2 acquisitions. All in just 24 months. - 40+ weekly hacking sessions. Retreats. Dinners. Resources galore – from incorporation support to cloud compute.
- A builder’s run club. 3,000+ founders, investors, builders, at our events. Come sprint with AIEB's Builders Run group. Or scale with us in AIEB's incubator. Or help build the most incredible AI founder community on the operational team. Or, of course, all of the above.

In the last 9 months, we've worked with 10+ growth equity funds, ranging from $100M to $2B AUM. We hear lots of funny (and horrifying) war stories. Here are some highlights:
** Anonymized for confidentiality **
• A VP accidentally sent their brutally honest IC memo to the target company's entire management team in a reply-all. The memo included "CEO gets defensive about churn metrics" and "CTO seems overwhelmed." They lost the deal and now their banker jokes about it every time they chat.

I just moderated partners Konstantine Buhler & Charlie Curnin at Sequoia Capital famous for investing $100M+ into XBOW, Harvey, and Listen Labs.
Fun fact I learned: University of California, Berkeley started as a merger. The 1868 deal became the flagship for an entire state university system. This history trivia points to a critical lesson in company building.

Excited to announce Martin’s $2M seed round to build JARVIS in real life! We’ve been moving at light speed for the last 6 months and excited to keep accelerating!
Super grateful to Dawson Chen for being an incredible cofounder and friend. He’s an ultimate competitor and I wouldn’t rather be building this with anyone else!
Huge thanks also to our investors and early users for all of the great feedback and support.

Day 1 at Y Combinator's AI Startup School → mind blown.
In 24 hours I met founders who ship faster than most teams brainstorm and soaked up lessons from the people actually pushing the frontier. Five takeaways worth sharing:
1. Ambition is the only ceiling. Garry Tan opened with a clear reminder: AI turns individual effort into outsized leverage. The bottleneck now is how big you’re willing to think.
2. “Impossible” ages quickly. Sam Altman skipped the AGI quest because it sounded absurd. Five years later it feels inevitable. Bet on the future you want.
3. Naive questions build new rules. Jared Kaplan kept asking “But how much data, exactly?” That curiosity produced today’s scaling laws. Simple questions still hide giant answers.
