ARi vs Bresslergroup (Delve): overview
ARi
ARi traces its engineering roots to 2001 and began operating under the ARi brand in 2006, headquartered in East Peoria, Illinois, with seven additional locations across North America and Asia Pacific; the company reports more than 1,100 employees. Embedded software and firmware sit inside a much broader industrial engineering business that also covers mechanical product design, manufacturing engineering, industrial automation, and robotics, so ARi suits a client whose project spans hardware, firmware, and manufacturing rather than firmware in isolation. Its scale supports large industrial programs that a boutique firmware firm could not staff alone.
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.
