Hardware startups need suppliers but don't have sourcing teams. Search 105,000+ companies for free — find suppliers for prototypes, small batches, and first production runs.
How 3E Helps
Free to Start
5 free unlocks per month — enough to source components for a prototype. Search is always free and unlimited. When you need more, credit packs and unlimited plans are available.
Beyond Mouser and Digi-Key
Catalog distributors work for standard parts. When you need specialty components, custom manufacturers, or small-batch suppliers, 3E searches 105,000+ companies that those platforms don't cover.
AI Finds Hard-to-Source Parts
Component selection drives BOM cost more than most founders realize. Our AI discovers suppliers you'd never find on your own — including brokers and surplus dealers with small-quantity availability.
No Minimum Orders
Our database includes suppliers who work with startups — small-batch manufacturers, prototype shops, and distributors without minimum order requirements.
Example
Sourcing a custom connector for a prototype
You're building a hardware prototype and need 50 units of a specific waterproof connector. Mouser shows it as discontinued. Search 3E — find 3 suppliers with stock, including a surplus dealer offering small quantities. Use one of your 5 free monthly unlocks to get their contact info.

How does 3E help with prototyping specifically?
