I'm unsure about how this works. Are you creating surveys that get filled up by users? How is AI going to validate a business idea without input from real users?
Some more information about your process would help - because it sounds interested as a service but leaves a lot of questions unanswered.
Its something I built without much expectation and now there's thousands of people using it everyday. I get emails from them saying how much they love it. So in that sense, I really want to keep running it.
Monetization is a bit tricky without making the userbase feel like we're selling out. I was more focused on making the user experience better before I think about monetization.
25% ownership doesnt appeal to me as much since I'd lose control over the direction and in that sense, I'd rather sell than work on it for someone else.
I'm not sure i want to sell but $50k is a decent chunk of money. I'm emotionally invested in the site but don't think about it as a revenue-generating business (or at least haven't so far)
