A brilliant idea means little if the market is too small to sustain it. Before investing months of time and savings, confirm that enough people need — and will pay for — what you’re offering. Many founders skip this step and assume enthusiasm equals scale. But enthusiasm without buying intent is noise. Estimate your total addressable market (TAM) and serviceable available market (SAM). Even a niche can work if it’s big enough or growing fast.
Validation comes from evidence, not intuition. Build a landing page to gauge sign-ups, run small ad tests, or collect early pre orders. Real signals — like people paying, sharing, or returning — matter more than survey optimism. If you can show traction at a small scale, you’re not just launching with confidence; you’re proving your market before it’s even official.
