Summary
Eight investors singled out 11 companies from Y Combinator’s Spring 2026 batch, with defense tech, AI infrastructure, developer tools and robotics drawing the strongest demand.
At least two startups were priced at $175 million or more, and counter-drone company 9 Mothers topped the cohort at upward of $200 million after booking $1.6 million in sales.
9 Mothers says one contract could expand to $35 million this year, while repeat founders also commanded a premium—Ploy soon announced a $27 million seed round after Demo Day buzz.
The rest of the standout list ranged from AI-agent testing and security to no-code software building, compliance automation, mobile MRI clinics and reusable space-return vehicles, underscoring how broadly investors are backing applied AI.
