Conclusive Engineering vs Bresslergroup (Delve): overview
Conclusive Engineering
Conclusive Engineering was founded in 2018 by Jakub Klama and Wojciech Kloska, based in Katowice, Poland, with a second office in Piaseczno near Warsaw. The team of roughly 30 engineers works across Linux, FreeBSD, RTOS, and bare-metal firmware, with particular depth in low-level debugging and hard real-time optimization for systems that cannot tolerate jitter. Because the founders came directly from kernel and driver-level engineering roles rather than management backgrounds, the firm stays hands-on with senior staff through the full engagement instead of handing projects to junior teams after scoping.
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.

Conclusive Engineering vs Bresslergroup (Delve): pros and cons
| Conclusive Engineering | |
|---|---|
| + | Founders bring direct kernel and driver-level experience rather than a management tier sitting over junior engineers |
| + | Covers Linux, FreeBSD, and bare metal, spanning more of the real-time spectrum than Linux-only vendors |
| + | Small team size keeps senior engineers hands-on for the full engagement instead of handing off after scoping |
| - | Roughly 30 engineers caps how many large programs the firm can staff at once |
| - | Founded in 2018, so its public track record is shorter than firms operating since the 1990s or 2000s |
| 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 |
