An AI agent marketplace where builders earn per usage - would love brutal feedback from this community

Been building quietly for a few months. Here’s the honest pitch and the honest problems I’m still figuring out. What it is: Users type a task. Gravity matches them to the best AI agent for it in 60 seconds. Builders who publish agents earn 20% every time their agent runs. The problem I’m solving: I talked to a lot of builders before writing code. Almost all of them said the same thing without me asking — “I built something good. Nobody uses it.” That’s not a builder problem. That’s a distribution problem. What I’m not sure about: • Is 20% compelling enough for builders to publish here over keeping agents proprietary? • How do you get the first 100 users onto a marketplace before there are agents, and the first builders before there are users? • Is the 60-second framing meaningful to users or does it feel like a gimmick? Pre-launch right now. Looking for 50 builders to be on the platform before alpha. What would make you publish an agent here as a builder?
