A solo founder shares an honest five-week account of attempting to validate startup ideas through LinkedIn outreach: 2,159 connection requests, 766 acceptances, 575 personalized follow-up messages, and only 4 genuine replies. The author tracks 27 validation signals (8 red flags) across three ideas, ultimately killing the one they were most excited about. A key moment of self-awareness: they built a custom CRM (~5,800 lines of code in two days) to manage the outreach process — recognizing it as a developer's instinct to retreat into building when the harder work of talking to strangers gets uncomfortable. Total spend: $261. The post is a candid rejection of the sanitized founder narrative, emphasizing that silence, red flags, and killing your own ideas are the actual work.
