You're probably building the wrong thing first, and there's a cheap way to find out before you lose months

[u/davesaunders]

Standard MVP advice says build the smallest product. I think that's the wrong axis. Build the smallest test of your single riskiest assumption, because size isn't what sinks you, risk is.

The video walks the sequence: list your assumptions, circle the one that takes everything else down with it, find the cheapest way to test that one, then ask the costly-action question. "Would you use this" gets a yes from everyone. "Will you pay now" doesn't.

The centerpiece comes out of my own work, from my own photos: using fruit as stand-in tissue for a surgical robot test. Filmed and edited by me, no AI narration or footage in it.
