I made the open protocol layer behind my B2B supplier matching project public

I’ve been building MapleBridge, a sourcing workflow for North American buyers looking for better-fit Chinese manufacturers.

One thing I kept running into: supplier search is not only a search problem. A buyer can have a very specific brief — product, MOQ, target market, packaging, certification path, timeline — but most supplier directories still reduce that into keywords and listings.

So I separated part of the work into an open layer.

MapleBridge Open documents how I think about:

- buyer intent

- supplier capability

- match explanation

- What still needs human review before an introduction

It does not include customer data, private ranking logic, crawler sources, or production prompts. It is more like a public protocol layer for AI-to-AI supplier search.

I’d be interested in feedback from anyone thinking about agent workflows, marketplaces, or structured matching.
