I've had this debate with a dozen founders over the past year. Half swear by "just ship it" — build fast, throw it out there, see if anyone cares. The other half won't write a single line of code until they've got pre-orders or waitlist signups.

The problem: doing it properly took me 2–3 weeks of research per idea. So I built a tool to compress that into 30 minutes.

FounderSpace (https://www.founderspace.work/) runs your idea through a structured validation framework — market analysis, competitor landscape, target customer clarity, and a viability score — before you commit a single sprint to building.

It won't tell you "your idea is great." It'll tell you where your assumptions are weakest and what you'd need to prove before building.
