Offer 1 — Revenue share
You earn on every subscription.
We sell access to your tool’s AI integration on the B77 marketplace and pay you commission on every subscription it earns. New revenue from a surface you don’t have to build or maintain.
For SaaS makers, API owners & developers
List your software on B77.
We build the MCP, you earn commission.
Your customers already live inside Claude, ChatGPT, and Cursor. B77 builds and operates an MCP server against your existing API, sells access to it on the marketplace, and pays you commission on every subscription. You don’t write a line of MCP code, and you don’t run any infrastructure.
Offer 2 — We do the work
We build the MCP for your API.
You don’t write a line of MCP code. We co-build the server against your existing API, host it, meter it, bill it, and support it. You review and approve; we operate.
How publishing works
Three steps. In partnership.
- 1
Apply
Send a short note about your product and its API. A B77 representative gets back to you within a few days.
- 2
We agree terms
Scope, pricing, and commission are agreed individually per partnership — there is no one-size-fits-all rate card.
- 3
We build & launch
B77 engineers build the MCP server against your API, host it, wire auth and billing, and publish the listing. You review; we operate; you earn.
What the partnership includes
We build the MCP
Our engineers design and build the MCP server against your existing API. You don’t need in-house MCP expertise and you don’t write a line of MCP code.
Hosting & operations
EU-hosted infrastructure, monitoring, and upgrades — operated by B77, reviewed with your team.
OAuth & auth
Pre-wired OAuth 2.1 flows. We handle the Claude, ChatGPT, and Cursor specifics so your users just connect.
Billing & metering
Stripe-backed subscriptions and metered usage. We bill, we meter, and we pay you commission on every subscription.
Distribution
Featured slots, category pages, and editor's-pick exposure across the B77 marketplace.
Support
A direct channel with the B77 team — during the build and after launch.
Operated, not just listed
Real products run on B77.
Easyweek — a ~20-person SaaS — operates on the platform, alongside first-party apps. We build and run MCP servers in production, handle their OAuth, billing, and uptime, and answer for them when something breaks at 3am. That’s the difference between a directory and an operator.
FAQ
Questions from publishers
Do I have to build the MCP myself?
No. That’s the core of the offer — B77 builds and operates the MCP server against your existing API. You bring the product and the API; we bring the integration, the AI-client plumbing, and the marketplace.
How do I get paid?
Revenue share. We sell access to your tool’s AI integration on the B77 marketplace and pay you commission on every subscription. Exact terms are agreed per partnership — there is no fixed rate card.
Is there a self-serve upload?
No. B77 is curated. We publish a small number of apps and co-build each one, so quality and operability stay high. You apply, we talk, we build.
Who already runs on B77?
Easyweek, a ~20-person SaaS, operates on the platform — alongside first-party apps like Time and Nightscout access. We operate real products in production, not demos.
