Apply to Become a Supplier: Join the Trustbridge Manufacturing Network

Trustbridge is a modern manufacturing network built on quality, transparency, and trust. We work with vetted suppliers around the world to deliver CNC machining, injection molding, sheet metal fabrication, casting, 3D printing, and more — for startups, scaling product companies, and global OEMs.

If you’re a supplier who takes pride in your work and wants to build lasting customer relationships — not chase anonymous RFQs — we’d love to hear from you.

Why Join the Trustbridge Supplier Network?

Jobs Curated by Engineers – No spam. No cattle calls. Only projects that fit your capabilities.
Fewer Quotes, Higher Win Rates – We don’t send jobs to dozens of vendors. If you’re selected, it’s because you’re a match.
Clear Communication – Our team stays involved to make sure expectations are aligned and questions get answered.
Production-Ready Customers – We work with real companies making real products — not tire kickers.
Long-Term Relationships – Many suppliers become go-to partners for recurring work, not just one-off jobs.
Growth & Incentives – Preferred partners may earn access to premium projects, referral bonuses, and even phantom equity participation in Trustbridge’s long-term growth.
