Demo output 1 — AI-powered startup validation tool1. The decision in briefGO to test—not yet to build. A focused validation sprint fits the stated solo-founder budget and time, but the inputs contain no customer behavior or evidence that founders will use a dedicated tool. The supplied market counts are unverified founder assumptions, not proof of demand; begin with interviews and a manual workflow before committing to software.2. What we know—and do not know•Founder-provided: The proposed idea is an AI-powered startup validation tool that would analyze market signals, competitor activity, and search trends, then return a structured report. The intended users are indie hackers, solo founders, and early-stage entrepreneurs. The founder supplies a TAM estimate of 5M aspiring founders globally and a SAM estimate of 500K active indie hackers, plus a solo founder, $5,000 budget, three months to MVP, part-time development, and validation as the main concern. These market counts and proposed product capabilities are unverified inputs, not established facts.•Sourced: None. No external claims were checked or needed for this first sprint.•Hypotheses / unknowns: Whether the target users face a recent, costly validation problem; what they currently do instead; whether they will complete a guided workflow; whether the tool can access reliable evidence for market, competitor, or search claims; and whether AI adds value beyond a manual checklist. No such product capability, customer interviews, usage data, acquisition access, or test results were verified or supplied.
