How to Validate a Startup Idea in 5 Minutes

Learn how to validate a startup idea in 5 minutes using AI and a proven problem–solution fit framework.

In this episode of The B2B Growth Engine, Mike walks through a custom GPT that helps founders quickly assess whether a real, painful problem exists and whether the proposed solution is actually desired. The workflow guides you through your startup hypothesis, user interviews, current workarounds, early validation signals, and willingness to pay.

In just minutes, the GPT generates a clear evaluation score, highlights gaps in your evidence, and recommends practical next steps—so you know whether to keep validating, refine your idea, or move toward product–market fit. Mike demonstrates the full process using mock data to show how fast and practical early-stage validation can be.

If you’re a startup founder, marketer, or advisor, this video shows how AI can reduce guesswork, improve decision-making, and help you avoid building a product the market doesn’t want—before you invest serious time or resources.
