AI is moving into the physical world. We're excited about a new wave of startups rebuilding the systems that power the real world, from education and healthcare to defense, finance, infrastructure, and work itself. ycombinator.com/rfs↗

Today we're launching Paxel: a free tool that analyzes your Claude, Codex, and Cursor coding sessions and gives you a profile of how you build with AI. It runs locally inside Docker, and your code never leaves your machine. Try it at t.co/HqSHneQSTQ t.co/ykmg52NLDR↗

Over the past year, we've been building our own internal agent infrastructure at YC: over 350 tools, self-improving skill loops, and a shared organizational brain that gets smarter overnight. In this episode of the @LightconePod, we sat down with YC General Partner Pete @koomen…↗

AI has stopped being a feature and started being the foundation. We're excited about a new wave of startups rebuilding software, services, and silicon— and pushing AI into the physical world. ycombinator.com/rfs↗

.@polymath_labs is training world generation models to automate the creation of RL environments. Traditionally, RL environment generation has been bottlenecked by human data. Superintelligence will never be achieved by human data alone. Polymath is building the core technology…↗

OpenClaw is a new viral and scarily effective virtual assistant. But it's so hard to set up that even most engineers give up. @usebits_inc will set up your secure OpenClaw instance on the cloud, batteries included, in 5 minutes. Congrats on the launch @rob0the0nerd and …↗

Coding agents are no longer a distant idea—they're already starting to reshape how we work. YC's Tom Blomfield (@t_blom) and David Lieb (@dflieb) discuss how AI coding tools are transforming software development, why small, high-agency teams will be able to do what once took arm…↗
