FoundersChecker

The tool takes a submitted startup idea and returns a one-shot analysis covering market viability, competitive saturation, and failure risks — no account required for the core verdict. The vendor states results arrive in roughly 30 seconds. The free tier surfaces the top risks and an overall verdict; the full breakdown is a paid-only feature. There is no API, no self-hosted option, and no agent layer — it is a single-input, single-output web tool. That simplicity is the point, until you need to compare twelve ideas in a batch or push results into your own workflow.
