Show HN: GoViralPromo – Replace ads with performance-based contests (free beta)

Hey HN, I'm the builder.

I burned $10K on Facebook ads watching my last startup die (60-80% of clicks were bots). I built GoViralPromo to apply crowdfunding psychology to marketing: instead of a random draw, contest participants compete on a leaderboard by running mini-campaigns for you.

The idea is to create a much lower, more predictable CAC.

The reality: It's a v1 and I have zero customers. I'm offering free campaigns to the first few people from HN to help validate (or invalidate) the model.

Tech stack: Next.js, Prisma, and PostgreSQL.

I'm here all day to answer questions. Open to all feedback, especially technical critique!
