Closera (@closera_ai) is building AI employees for commercial real estate. They automate brokers’ most repetitive workflows across sales, marketing, and property valuation, saving them 30+ hours a week. Congrats on the launch, @anmoltukrel & @chinpatel!

We're hosting a Context Engineering event in SF! ​Learn how leading applied AI teams are engineering their context windows. Hear from: Jake Heller, CEO @Casetext ​Beyang Liu, CTO @Sourcegraph Sam Bhagwat, CEO @Mastra_ai Jeff Huber, CEO @trychroma RSVP:

Epicenter (@epicenter_so) is building a database for your mind. They're designing a @sveltejs ecosystem of apps sharing a local memory: a folder and SQLite file. Open-source, open-format, and fully yours. Congrats on the launch, @braden_wong_!

Anytrace () is your AI support engineer. It can resolve technical tickets end-to-end by talking to customers, investigating issues, and managing the full ticket lifecycle. Congrats on the launch, @samgoldman0 & @tairabun!

I met a founder today who said he writes 10,000 lines of code a day now thanks to AI. This is probably the limit case. He's a hotshot programmer, he knows AI tools very well, and he's talking about a 12 hour day. But he's not naive. This is not 10,000 lines of bug-filled crap.

Embedder (@embedderdev) is launching once every week. Our goal is to be the "most launched" company by the end of the YC S25 batch. Today, we're launching large codebase understanding, serial terminal interaction, and a brand new web console for managing your projects. Bob & I have been working with the team a Pebble, the creators of the first smart watch, to make this demo!

The @slashapp team just launched Global USD. It's the first platform that gives international businesses a real USD account—without an LLC, EIN, or compliance nightmares. Businesses in 100+ countries can use it to send and receive ACH, wires, and USDC/USDT.

A new AI research lab called @blankbio_ launched today. They are building new foundation models for mRNA, and are one of the strongest technical teams I've worked with. I'm particularly excited about their new model results, and the wide set of application areas for it.

I think once successful founders get liquidity they owe it to society to reinvest some of that capital into building hard, high risk, high potential things. I want to keep building cool new things that will accelerate human progress.

We're excited to be OpenAI's default search tool in gpt-oss!
