“For Curiosity Quench as an example I posted a video 60 seconds on TikTok. I just point and shoot recorded it talking to the camera and 15 people commented saying 'I need this this is it this is good.' So I kept making videos, the same thing happened, and eventually I realized hey I should probably make this thing that hundreds of people say they want.”

Jack validated Curiosity Quench by filming a single 60-second selfie TikTok describing the idea — no landing page, no pre-orders. When 15 strangers commented 'I need this,' he kept posting; when hundreds said it across more videos, he built. The signal is unsolicited 'I need this' comments, not likes or views.
