YC: we're all in on these directions — if you're building one, come get funded
- YC, the world's best-known startup accelerator (Airbnb and Stripe both came out of it), has laid out the 13 directions it most wants to fund in fall 2026. The subtext is simple: we love these, so if you're building one, come get funded. And if you're not, you can still apply.
- This batch has one unifying theme: AI stepping out of the screen and into the real world — defense, elder care, job sites, the ocean. Pure generative AI (text-to-image, text-to-video, the models themselves) is almost entirely absent this time.
- For the first time ever, one direction was written by the sitting U.S. Secretary of the Army himself. He's openly asking founders for low-cost interceptors and for sensors and drones that plug into the military's open architecture — the goal being to drive down the "cost per kill."
- Why bet now: intelligence is finally good enough (you can treat an Agent like a person you delegate to), and costs are falling 10x a year. YC figures the consumer tipping point is right around the corner.
- For founders, it's a ready-made map of what to build. For everyone else, it's an official signal of where the world's top accelerator is putting its money in 2026.
First, what exactly is this YC list
YC is the world's best-known startup accelerator — Airbnb, Stripe, and Coinbase all came out of it. It makes money by betting on the next company like those. So every so often it publishes a list of the directions it most wants to fund, with one simple subtext: if you're building this, come get funded.
The list is called RFS (Requests for Startups). The fall 2026 batch has 13 entries, and there's a single theme: get AI out of the screen and into the real world. Each one is written by a YC partner or a working founder, spelling out the pain point, the opportunity, and what they'd like someone to build.
So the list works on two levels: it points founders toward opportunities, and it's YC publicly shopping for companies. These are directions it's genuinely excited about — build one and come get funding and support. YC also says up front that the list is just a way of sharing what's on its mind: even if you build none of these, you can still apply.
All 13 directions, laid out on one table
Thirteen sounds like a lot, but they group into four buckets. Scan the whole map first to get your bearings.
Why this batch is all about the physical world
String the 13 together and a through-line emerges: for the past few years, AI's battlefield was almost entirely inside the screen — writing code, generating text and images, answering questions in a chat box. This batch, YC pushed its chips beyond the screen.
Defense, moving compute out to sea, an OS for job sites, gathering physical-world data — all of these have to grapple directly with hardware and the offline world. Even the consumer-and-society entries carry a strong offline flavor: elder care depends on in-home monitoring and robots, education is aimed at real children, and "prove you're human" tackles exactly the trust that's breaking down both online and off.
