Congrats to the @Whatnot team on raising at $11.5B A few unknown facts about this amazing cofounder duo @GrantLaFontaine and @loganhead13 1/ They launched in 2020 right before COVID hit. 2/ in the early days, they even funded payroll for some of the early employees. 3/ They

Congratulation to Whatnot YC w20 on hitting Decacorn status. They are a terrific example of the heads-down execution oriented founders we tell every YC team to emulate! https://t.co/X5PzJSsbE1

I grew up in sf. I went to Cal, and have lived in sf my entire life. I’ve gone to over a hundred tech events, and have organized a few myself. RL IRL was the best tech event I have ever gone to, by far. Kudos to @adelwu_ and all the organizers and speakers.

.@fulcrumML, one of the highest firepower s25 teams I worked with is open-sourcing some practical tools for coding agents today: orchestration, monitoring, and critique. The best AI tools don't just make models more capable, they make people more capable. Orchestra from the
Today, we’re excited to announce that we’re open-sourcing two tools: Quibbler is a background agent that critiques your coding agent’s actions. Orchestra is a multi-agent coding system: it uses a designer agent that spawns and coordinates your parallel coding agents.

A bunch of great YC companies are throwing a Reinforcement Learning rager at YC HQ on Saturday. I’ve seen the RSVP list and it is spicy!
Sharing the full schedule for RL IRL (Saturday at @ycombinator) below! We're finalizing the guest list tonight - this is the last chance to RSVP. (Also, a sneak peek at some of the @Osmosis_AI merch we're handing out!)

For the latest episode of "Office Hours" we polled YC founders for hard questions they're dealing with and took a crack at answering them. Many were about timing: When to pivot? When to improve model performance vs. wait for the next release? When to open source? If you're
Every founder faces moments where they’re not sure what to do next — such as how to go to market with AI products, when to pivot, and who/when to hire. In this episode of Office Hours, YC partners @koomen, @bradflora, @dessaigne, and @gustaf answer real questions from founders

The Deel story is a great example of why putting the smartest founders in a YC batch together is such an unfair advantage. They broke out of pivot hell by paying close attention to how another YC startup wanted to use their product, and shifted the entire direction of the
Deel has raised $300M at a $17.3B valuation We started about 6 years ago, struggling to even make $10K. I've never shared this before because of how embarrassing our start was. The story of how we went from $1K to $1B and the advice I'd give to my younger self:

It’s time (for your agent) to learn.
We've raised $7M to help companies build AI agents that actually learn and work. @Osmosis_AI is a platform for companies to fine-tune models that outperform foundation models with reinforcement learning. Better, faster, and cheaper.

We are in a full infrastructure rebuild of the softwares stack. Large models are important, so as fast, purpose-built models to meet the demand of coding agents. That’s what you get from @relace_ai : instant apply, reranker, embedding models and more, for all your coding needs.
