DeepSea Developments vs Promwad: overview

DeepSea Developments

DeepSea Developments was founded in 2017 and is headquartered in Palo Alto, California, with a team in the 11 to 50 employee range. The firm works on electronics, IoT, hardware, and firmware development, sized specifically for early-stage hardware startups building a first connected product rather than for large enterprise programs. Its Silicon Valley location puts it close to the startup ecosystem it primarily serves, and the small team keeps communication direct without account-management layers between the client and the engineers.

Promwad

Promwad was founded in 2004 and moved its headquarters to Essen, Germany, with engineering centers in Latvia and Serbia and a team in the 101 to 250 employee range. The firm's core work covers embedded software, embedded Linux, hardware design, and FPGA programming, with device driver and board support package engineering delivered as a defined service line rather than an incidental capability. Promwad markets itself as an independent design house, meaning it takes on both firmware-only engagements and full electronics-through-manufacturing programs depending on client scope.
