YC’s hard-tech share hit 20%, AI startups reached $20K monthly revenue, and solo founders rose to 19%.
YC’s latest batch reveals a startup ecosystem shifting from bits to atoms. Hard-tech companies rose from 8% to 20%, including robotics at 6–7%, industrial manufacturing at 10%, defense at 5%, and compute semiconductors and power infrastructure approaching 4% and 3%. AI is accelerating this shift by reducing software headcount needs and enabling breakthroughs in robotics, defense, manufacturing, and data centers. Meanwhile, median YC startup revenue by batch end jumped from $8,000 to $20,000 monthly, with some companies reaching seven-figure revenue in three months instead of 18 months. Data and RL-environment startups have also exploded: more than a dozen YC companies now exceed $10 million annually, while major labs reportedly spend about $1 billion in this market. The founder profile is changing too: solo founders grew from 5% to 18–19%, and experienced founders in their 30s, 40s, and 50s are increasingly succeeding as AI makes building and managing coding agents dramatically easier.
