Unmanned Vehicle Startups funded by Y Combinator (YC) 2026

Isengard Industries is not another drone company. We build sovereign production: the means for allied nations to make precision-strike and counter-drone systems by the thousand, on their own soil, at a fraction of what the primes charge. We call it Weapons of Mass Production. The Arsenal of Democracy, rebuilt for the drone age. More to come, and only where it helps. You know how to reach us.

Polymath is building a general autonomy stack for cautious vehicles. Our software allows any industrial vehicle - whether it's a tractor in a field or a bulldozer in a mine, drive itself. We bundle together AI, ML, Controls, ROS, Safety and best-in-class deployment practices to enable our customers to tell automated vehicles to do via a REST API. We're on more robots than we have engineers, are seeing our revenue (and robotic fleet) grow rapidly, and are looking for folks who want to help automate the world.

Did you know that if your car is eligible for booting and towing in NYC, all of your registered vehicles are eligible? Now imagine you have thousands of vehicles in thousands of cities. We make sure that your vehicles are compliant.
