The SAFE Trap: What a W26 Founder Signed at 2am

A W26 founder signed a $40M post-money SAFE at 2am in a parking lot and thought she had made it. Six months later, three stacked SAFEs had quietly committed 30% of her company before a Series A conversation even started. In this episode of Year One, Miles and Grant walk through the exact dilution math with the founder herself, uncovering how a single cap concession to close one reluctant investor triggered an MFN cascade she never modeled and never saw coming. She admits she did not know what Most Favored Nation meant when she signed YC's standard docs. A YC partner then breaks down the two fear-based SAFE cap mistakes they see again and again post-Demo Day, and why founders who treat the cap as a confidence signal end up with a Series A math problem they cannot solve. No clean resolution here — her cap table is still on the table. This episode is essential listening for any first-time founder heading into Demo Day or sitting with an unsigned term sheet right now.
