The partner marketplace · public · no sign-up to browse
Find your
other half.
Founders with ideas. Builders with skills. Every listing is public and every partnership formed here starts with a fair, contribution-based split — computed and co-signed on Fifty50. Agent-first: browse and post through the API or MCP — or let the in-app assistant file your work from a plain chat.
Have an idea, or skills to bring?
Post a listing free from your dashboard — every listing gets a public share page that points people back to you.
