Before You Start Searching.
Do I need an account to browse suppliers?
No. Public supplier profiles are open to anyone. Create a free buyer account when you want full supplier pages, details and the ability to send RFIs.
Is it really free for buyers?
Yes. Searching, viewing full profiles, sending RFIs and messaging suppliers cost buyers nothing. There are no seat limits.
Can I find shops for prototypes as well as production?
Yes. The network includes shops set up for prototype and low volume work alongside production machine shops. Profiles show capabilities and scale so you can judge fit before you reach out.
Are you a broker or middleman?
No. We verify suppliers and then step aside. You deal with suppliers directly, own the relationship and we never take a cut of the deal.
What is an RFI, and why send one before an RFQ?
An RFI is a structured request for information covering capability, capacity and fit. It lets you confirm a real match before asking for pricing, so the RFQs you do send go to the right shops.
