How are you validating ideas?

Hey guys, I’m a non technical founder who built a prototype of my product using ai. It doesn’t work but it has a minimal front end with an idea of how it would work.

My strategy is to create an organic audience while simultaneously trying to find atechnical confounder.

But before even any of that, how are you validating ideas?

My thoughts would be to message people on Reddit / x / instagram on viral posts related to my topic, send them a quick product demo video and a feedback form to see what they think and if they would even use it

But curious to hear what others have done or are currently doing.
