How it works
You build your projects publicly, using Zerion API. Here's what we put behind you.
Team up with strong builders
A 10-person cohort, handpicked from 1,000+ applications. Weekly calls where you trade notes on who shipped what — you build alongside people as serious as you are.
Backed by the Zerion team
Free Zerion API credits, plus direct feedback from the people who built it: Ilya on market, Evg on business, Grayson on tech and dev, Chris on content and storytelling.
Prizes and real reach
Three monthly $1K prizes — most viral project, best use-case, best tech — and distribution through the Zerion X account, Featured Dapps, and our Ambassadors.
What we expect from you
The program runs on what you put out into the world.
