ByteSnap Design vs Capgemini Engineering: overview

ByteSnap Design

ByteSnap Design was set up in Birmingham in 2008 and works from Park Point in Longbridge. It designs printed circuit boards, embedded Linux and firmware, FPGA logic and low-power wireless products, including ATEX-rated designs for hazardous areas and EV charging controller boards. The team is under 50 people. In December 2025 it reported 13% turnover growth and launched an automated board-test service and an obsolescence management service.

Capgemini Engineering

Capgemini Engineering is the result of Capgemini's purchase of Altran, which closed in April 2020. Revelio Labs estimated around 64,700 employees in September 2025, down about 5% on the year. It combines Altran's engineering and R&D services with Capgemini's digital manufacturing work, and analysts pointed to Altran's operational technology skills as the reason for the deal. It is the strongest option here for large, compliance-heavy programmes.
