A developer built ideation.biz, an AI-powered market validation tool that analyzes startup ideas in under 5 minutes. The tool runs ideas through a multi-step AI pipeline producing structured analysis across modules including TAM/SAM/SOM sizing, competitor intelligence, SWOT, customer segmentation, risk models, go-to-market strategy, and financial projections. Three depth tiers are available starting at $1. The builder notes the key technical challenge was designing a prompt chain where each module feeds context into the next rather than producing isolated outputs.
