Witekio vs Bresslergroup (Delve): overview
Witekio
Witekio was founded in 2001 and is headquartered in Lyon, France, with a team of 150 or more engineers. The firm's practice centers on board support packages, RTOS integration, and embedded Linux, but its most distinct offering is a dedicated secure OTA update and low-power wireless connectivity practice covering Bluetooth Low Energy, NB-IoT, and LoRaWAN. More than two decades of continuous operation gives the firm a longer public reference base than most boutique competitors on this list, though it does not publish pricing or minimum engagement figures.
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.
