Sirin Software vs Capgemini Engineering: overview
Sirin Software
Sirin Software was founded in 2014, headquartered in Pompano Beach, Florida, with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, and a team of roughly 30-50 engineers depending on the source. The firm specializes in SDKs, firmware, middleware, and drivers for semiconductor companies and IoT product teams, with named depth in wireless connectivity stacks including Wi-Fi, BLE, Matter, UWB, NFC, and LoRaWAN, and embedded software stacks including Linux, Zephyr, FreeRTOS, and ThreadX. This wireless-protocol depth is Sirin's clearest specialization relative to broader embedded generalists on this list.
Capgemini Engineering
Capgemini Engineering traces its roots to Altran Technologies, founded in 1982 in France by Alexis Kniazeff and Hubert Martigny, which grew into a major engineering and R&D consultancy before Capgemini acquired it in 2019 and rebranded the combined engineering business as Capgemini Engineering in 2021. Headquartered in the Paris region (Neuilly-sur-Seine), the firm now employs somewhere between roughly 45,000 and 52,000 people worldwide depending on the source, with electronics and embedded engineering representing one technical domain within an extremely broad engineering-and-innovation consulting portfolio spanning nearly every industry.

Sirin Software vs Capgemini Engineering: pros and cons
| Sirin Software | |
|---|---|
| + | Named depth across a wide range of wireless protocols (Wi-Fi, BLE, Matter, UWB, NFC, LoRaWAN) rather than a single connectivity stack |
| + | Works directly with semiconductor companies on SDK and driver development, not just end-product firmware |
| + | Combined US headquarters and Ukraine R&D centers balance client-facing presence with delivery cost efficiency |
| - | Reported team size varies by source (11-50 employees), making exact delivery capacity hard to pin down |
| - | Small team size limits capacity for very large, multi-workstream programs |
| - | Public pricing and minimum engagement are not disclosed |
| Capgemini Engineering | |
|---|---|
| + | Extremely large global scale (45,000+ engineers) can absorb programs no boutique or mid-size firm could staff alone |
| + | Broad engineering domains beyond embedded (mechanical, systems, cloud) available under one contract for complex products |
| + | 40+ year engineering consulting heritage predating the 2019 Capgemini acquisition and 2021 rebrand |
| - | Acquired by Capgemini in 2019 and renamed from Altran in 2021 — buyers should confirm which legacy Altran teams and processes remain intact post-rebrand |
| - | Embedded/electronics engineering is one technical domain within an extremely broad portfolio, not a dedicated specialization |
| - | Scale and process overhead of a firm this size is a poor fit for small, fast-moving embedded projects |
