Submit your AI tool where people already search for one. Start with a niche AI tool directory (There's An AI For That, Futurepedia, and Vibedonalds for vibe-coded products), add a couple of general startup and SaaS directories, launch on one platform (Product Hunt or a smaller one like Uneed), and post in one community (a relevant subreddit or Show HN). Spread more directory submissions over the following weeks to get your first users.

The expensive mistake in the vibe-coding era isn't building the app — it's building the wrong one. You validate an AI app idea by talking to about eight people in your target market before you build, and listening for the single capability they all wish existed. That's your wedge. Higgsfield's founder did exactly that on the way to a ~$200M run-rate.

Launch on Product Hunt by preparing for a few weeks: build genuine account activity, line up your assets and a supporter list, and ship at 12:01 AM Pacific (the daily reset) on a weekday. Reply to every comment all day, never ask for upvotes (say 'check it out'), and keep working the week after — that's where most of the lasting value is.
