“No one was building a product around it. I knew this is a good idea — I didn't do any validation or anything. I just said, if I don't do this, someone else will.”

When you see demos of a capability but no real product wrapping it, that gap itself is the signal. Treat speed as the validation — if you don't build it, someone else will, and the window closes fast.
