Robots Made in America: what YC wants and how to validate it
Original request by Diana Hu, Y Combinator. Source: YC Requests for Startups.
The request in plain English
Robot software is improving fast, so the bottleneck has moved to hardware, and most of that hardware is imported. YC wants companies that build the American robot supply chain itself, not just assemble robots from foreign parts.
What YC's request says
- Robot foundation models are now transferring skills between different robots.
- The US installed 38,400 industrial robots in 2025, up 12%, most of them imported.
- China made 94% of the world's sintered rare-earth magnets in 2024.
- A 2025 FCC rule stops authorizing new connected mobile robots unless they are made domestically or exempt.
- Robots must have over 65% domestic component cost, rising to 75% in 2029.
Why now
Two things changed at once. Robot intelligence got much better, so demand for capable robots is rising. And policy started pushing hard toward domestic manufacturing, with component-content thresholds that most current robots cannot meet.
That combination creates a rare situation: customers who want to buy, rules that require them to buy domestic, and very few domestic suppliers. Every component on the list, from magnets to strain-wave gears to encoders, is a potential company.
Why components beat whole robots
Building a complete robot means competing on everything at once: mechanics, software, sales, and support. Building one component means selling to every robot maker who needs to hit a domestic-content threshold. The buyer list is long, the requirement is concrete, and the purchase decision is driven by compliance as much as price.
Components also have clearer specs. A motor or encoder either meets the torque, precision, and reliability requirements or it does not, which makes the sales conversation faster than pitching a general-purpose robot.
Three startup ideas to start from
Domestic actuator modules
Motor, gearbox, and encoder in one unit, designed to drop into humanoid and mobile robot joints and count toward domestic content.
Rare-earth-free or recycled magnets
Magnets for robot motors made from recycled material or alternative chemistries, sold on supply security rather than price.
Compliance and sourcing software
Track component origin and domestic-content percentage across a robot's bill of materials, so makers know where they stand.
How to validate it before you build
- Talk to robot makers about which component is hardest to source domestically. The answer should repeat across conversations.
- Ask for their current unit price and volume for that part. Your cost target comes from their spreadsheet, not yours.
- Get a paid engineering sample order before building a factory.
- Confirm how the domestic-content rules count your part, so the compliance value is real.
The founder trap
Underestimating how long it takes to qualify a hardware component with a manufacturer. Budget for long test cycles and design partners, not a fast software-style sales loop.
IdeaCheck's take
Rare alignment of demand, policy, and supply gap. Capital-intensive, but components with clear specs and compliance pull are the most fundable entry point.
