Day Zero exists so early backers see tools 6–12 months before they show up on late-stage deal sites. The first verticals are AI and developer tools.
Every campaign is a pre-purchase of lifetime access. You are not buying a stake in the company, and the product usually does not exist yet beyond a prototype and a Loom.
Every founder passes identity verification before listing, and every campaign shows the delivery date, milestones, and the founder's public track record before you pay.
Pick the tool you will actually use. Portfolios are public at @username so your taste is the reputation layer — not a prize pool.
