Hey hunters 👋 I'm launching BuildSignal because I've shipped six products. Five died. One — ProxiesAPI (https://proxiesapi.com) — has been profitable since month three. No VC, no cofounder, still running. The difference wasn't the idea. It was the research. Before I wrote a line of code for ProxiesAPI, I spent weeks in Reddit threads mapping what developers actually complained about, who was paying for garbage alternatives, and where incumbents had stopped caring. The other five? I built on vibes. You know how that ends. BuildSignal is that exact process — automated, and done for you every day. Each brief is 15 sections of real validation: 🔥 Real user pain, with sourced Reddit quotes 💸 Willingness-to-pay signals (who's already paying, and for what) 🎯 G2 deep-dives into incumbents' 1- and 2-star complaints — the gaps nobody's filling 📈 Market shifts per niche — regulation, funding surges, tech transitions 🧭 An honest BUILD or SKIP verdict. We don't hedge. When a brief grabs you, the app keeps going: shortlist ideas, compare them side by side, generate a founder-sized PRD in one click, and auto-generate a validation questionnaire you can send to real users — talk to 5 people before you build for 5,000. It's not for everyone. If you want motivation or a wall of AI-generated "ideas," this isn't it. It's for people who've shipped before and know what good validation looks like — who'd rather read for 10 minutes than research for 40 hours. Founding offer: lifetime access for a one-time $99, before we move to a monthly subscription. 90+ briefs live now, a new one added every day. Would love your feedback — and happy to answer anything about the research methodology in the comments. 🙏
