DeepSea Developments vs Bresslergroup (Delve): 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.

Bresslergroup (Delve)

Bresslergroup was founded in 1970 in Philadelphia, Pennsylvania, and reports roughly 83 employees. In 2021 the firm merged with the Midwest design consultancy Delve under Trinity Hunt Partners' ownership, and by June 2022 the combined company adopted the single Delve brand name, so new engagements are contracted under that name even though the Bresslergroup engineering history and team carried over. Its practice covers new product definition and development, including industrial design, mechanical and electrical engineering, and embedded software, for categories spanning consumer IoT products to medical devices.
