YCombinator announced its Fall 2026 request for startups. The categories reveal where the money thinks the future is heading. Some make sense. Others feel like throwing darts at a board of buzzwords.
Hi, my name is Tom Smykowski. I'm a founding engineer with 19 years in software, currently exploring my next opportunity. On this blog I write about AI, engineering, and building products that scale.
Y Combinator is the most influential startup accelerator in the world. Founded in 2005, it has funded over 4,000 companies including Airbnb, Stripe, Dropbox, Reddit, and Coinbase. When YC publishes a "Request for Startups," the tech world pays attention.
YCombinator lately announced its regular request for startups, and compared to previous ones, this one caught more attention than usual. Maybe the reason is that building is blooming. The question isn't how to build anymore. It's what to build, how to sell it, and how to keep building it.
The call includes categories like AI for kids, American defence, cloud for small software, multiplayer AI, compute at sea, and proving you're human. Each reveals something about where investors think the opportunities are.
