Apriorit vs Bresslergroup (Delve): overview
Apriorit
Apriorit was founded in 2002 and is headquartered in Needham Heights, Massachusetts, with delivery teams across Europe; the company reports roughly 242 employees across three continents. Its core positioning is cybersecurity engineering from kernel to cloud, and that security-first culture extends down to driver development, bootloader-level firmware, and reverse engineering of existing binaries. That specialization means the firm is a stronger fit for security-hardened firmware review than for the RTOS and connectivity work that dominates typical consumer IoT projects.
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.

| Bresslergroup (Delve) | |
|---|---|
| + | More than five decades of product-design and engineering history dating back to 1970 |
| + | 2021 merger with Delve added complementary design and engineering resources rather than a competitor absorbing a smaller rival |
| + | Covers industrial design, mechanical/electrical engineering, and embedded software in one engagement |
| - | The 2021 to 2022 rebrand to Delve means new client contracts and public materials now use a different company name than the one with the longer track record |
| - | Firmware is one part of a broader industrial design and product development practice |
