The State of Startups in 2026

Video summary

YC says hard-tech startups rose to 20% of its batch as AI helps founders build faster and reach revenue sooner.

Y Combinator’s latest batches show a sharp shift from software toward physical technology: hard-tech companies rose from 8% to 20%, with robotics reaching 6–7%, manufacturing 10%, and defense 5%. AI coding tools are lowering software barriers for technical founders, while demand for AI infrastructure is driving startups in data centers, chips, power, and photonic switches. Robotics may be nearing a breakthrough, but models still need specialized data and fine-tuning for real-world tasks. Meanwhile, software is evolving into AI agents that complete entire workflows, helping median YC companies reach $20,000 in monthly revenue by the end of a batch, up from $8,000; some go from zero to seven-figure revenue in three months. YC also reports solo founders now make up 18–19% of accepted companies, and experienced founders are gaining ground as AI makes building more accessible.
