Feasibility and quote

We check that it can be built, certified and sold at a profit, then send a written verdict and a fixed price for each stage.

Step 03 of 04

Build in stages

Design, prototype and test in rounds. Each round ends with a demo and your go or no-go before the next.

Step 04 of 04

FAQ

Questions inventors ask before the first call

A hardware product development company turns an idea for a physical product into something a factory can build. Inventornest, a hardware product development company in Toledo, Ohio, handles product design and development end to end: feasibility, industrial design, electronics and PCB, firmware, prototyping, certification and the handover to manufacturing. Unlike an invention promotion firm, we sell engineering work with defined deliverables. Unlike a contract manufacturer, we design the product too.
