Investors Chase 8 Startups at YC Winter 2026 Demo Day
TechCrunch reports on eight startups that drew strong investor demand at Y Combinator’s Winter 2026 Demo Day. Selection required being called a favorite by at least two VCs. The highlighted companies span space hardware (Beyond Reach Labs, GRU Space), networking and storage (Byteport), AI security and agent tooling (Hex Security, Stilta), autonomous agriculture drones (Grazemate), a multimodal data marketplace (Luel), and a generative-AI strategy game (Pax Historia). Several startups report rapid revenue traction (Hex, Luel) and multiple firms disclosed large letters of intent or early valuations — for example, GRU Space says it has $500M in LOIs and Beyond Reach Labs $325M in LOIs. The article notes a few deals priced near $100M and a prevailing seed “default” valuation around $30M this quarter.
