I got the call!!!

Zverev went years without a Grand Slam and now he’s won TWO in the same fucking year. Never give up on the grind!!

I’m grateful for the customers who buy our product and work with us to make sure it solves their business problems. They push us to get it right and stay patient as we close the gaps. Those customers are worth their weight in gold.

You need to build and own your own intelligence: your own agent, your own models, your own memory Join us for the YC Own Your Intelligence Hackathon September 27 in San Francisco events.ycombinator.com/gstac…

Today, we’re announcing @ArgaLabs’ $10M seed round led by @generalcatalyst. AI agents are taking consequential actions across real systems, but teams still lack a safe, realistic place to test them before production. Arga’s Real-World Sandboxes give teams stateful twins of external systems—letting them catch regressions, replay edge cases, and validate non-deterministic workflows without ever touching production. Teams at @slashapp, @MonacoGTM, @WorkWeave, @YCombinator, and more have already run 100,000+ tests on Arga in the past four months. Thank you to @BoxGroup, @emergencecap, @GradientVC, @svangel, and everyone else who backed us. Glad to be building with @akkkkiira. We’re just getting started. 🚀 P.S. We’re giving everyone 10 free sandbox runs. Reply or DM me! TechCrunch Article: techcrunch.com/2026/08/26/ar…

Today, we are announcing our $31M seed financing at Apollo Atomics. The $26M equity is led by FCVC with participation from Y Combinator, TeleSoft Partners, Alumni Ventures, Pelion Venture Partners, Duke Capital Partners, Robinhood Ventures, and Nucleation Capital. $5M of equipment financing is provided by Oak Ridge Financial. Apollo Atomics is the only nuclear company that can deliver high power output nuclear reactors (>80 MW) on a truck. The higher power density is the strongest argument for cost effectiveness and mass manufacturing in the nuclear industry today. We achieve this without relying on exotic/scarce fuel, unqualified materials, or high regulatory uncertainty. Achieving that goal is a mirage if you don’t build the right company. With Drew Walker, we have assembled an extremely talent dense team with Excellence, Intensity, and Execution at its core. We are running a low power reactor demonstrator within MIT and now building a full scale 1 MW reactor prototype under commercial reactor conditions. We work directly with the U.S. Nuclear Regulatory Commission to support a commercial deployment in 2028. Apollo Atomics is not hardware in vacuum, we are building software solutions for autonomous reactor control, licensing support, and reactor modeling to reduce OpEx and deployment timeline. Deeply grateful to our early investors for supporting our mission when no one else believed particularly Genesis Fund, Arjun Gupta, and New Era Ventures, to our early supporters within Massachusetts Institute of Technology, MIT Sandbox Innovation Fund Program, TNT, MIT Department of Nuclear Science and Engineering. Excited to have many brilliant individual investors supporting our mission including Paul Graham, Evan Meagher, CFA, Philip Johnston, Ray Rothrock, Matteo Franceschetti

codex six hours into a 15 minute task

Key lessons I learned from @paulg yesterday: 1. Grow 10 percent a week. If you optimize for growth, growth designs the product. Users tell you what to build next. 2. The growth rate is a decision filter. If code is not the limiting factor, stop writing software and go sell. 3. Fundraising is not winning. Money from customers is. A valuation is a prediction of future customer revenue. 4. Believe the no, not the why. Rejection reasons are breakup lines. 5. If everything else fails, keep a small group of users happy. Hang on to that like a rope in a hurricane.

I’ll totally use this in my next presentation.

The redaction feature is way cooler than the types imo. There is a lot of env leaks today while using agents, who knows where your api keys are being stored.

How cool is this?!?

I would really like a day with no @claudeai outage

Thank you Spain 🇪🇸 The better team won

GOAL!!!!!!!!

Argentina wining today is the equivalent of getting an A for attendance

England earned this!

Had a blast at Demo Day. But there's only one thing that matters the team:
