Fourteen companies in the YC W26 batch hit a million in ARR before Demo Day ended — three times more than the previous winter batch and the highest count in YC history. The question Miles and Grant press on in this episode of Year One isn't whether that number is impressive; it's what it actually costs to get there in ninety days, and whether the valuation it commands is earned or a cap table trap. They pull apart Hex Security, which reached $1M ARR in eight weeks by deploying AI agents for continuous penetration testing, and examine why their batch-as-first-customer strategy worked — and where it gets harder. They also surface a counter-intuitive finding across the full W26 batch: the fastest-growing companies didn't pivot, they held course. With the default round now sitting at $4M on a $40M post-money — double what W23 commanded — the Series A math deserves a hard look. This episode is especially relevant for early-stage founders deciding when to price their first round.
