It holds direct partnerships with NXP, STMicroelectronics, and Microchip as primary semiconductor partners, plus an in-house lab with oscilloscopes and hardware-in-the-loop testing for board bring-up. Public case studies include a KONVOI truck security firmware audit and a Caltech medical device port to STM32, and the company holds ISO 9001, ISO 27001, and ISO 13485 certifications with full IP transfer to the client on delivery.
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.

| + | ISO 27001, ISO 9001, and ISO 13485 certifications plus MISRA-aware testing suit regulated industrial and medical firmware |
| + | Full intellectual property and source code rights transfer to the client on every engagement |
| + | Named case studies span automotive security auditing, medical device porting, and industrial telemetry rather than one vertical |
| - | Does not manufacture finished devices or handle mass production in-house |
| - | Does not obtain product regulatory certification on the client's behalf; the client or a third party owns that process |
| - | Minimum engagement size is not published, so budget fit requires a direct conversation |
| Bresslergroup (Delve) | |
|---|---|
| + | More than five decades of product-design and engineering history dating back to 1970 |
