Sirin Software vs Capgemini Engineering: overview
Sirin Software
Sirin Software, founded in 2014, runs an 11-50 person team headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, specifically on SDKs, firmware, middleware, and driver development for semiconductor companies and IoT product teams. Small size here maps to genuine specialization rather than a limitation: named depth across six wireless protocols (Wi-Fi, BLE, Matter, UWB, NFC, LoRaWAN) spanning Linux, Zephyr, FreeRTOS, and ThreadX is a narrower, deeper claim than most much larger generalist firms make about connectivity work.
Capgemini Engineering
Capgemini Engineering traces its roots to Altran Technologies, founded in 1982 in France, before Capgemini acquired it in 2019 and rebranded the combined engineering business in 2021. At an estimated 45,000-52,000 people worldwide, this is the second-largest firm on this list by headcount — electronics and embedded engineering is one technical domain within an extremely broad engineering-and-innovation consulting portfolio spanning nearly every industry, about as far from a boutique specialist as this list gets.

Sirin Software vs Capgemini Engineering: pros and cons
| Sirin Software | |
|---|---|
| + | Named coverage across six wireless protocols is a narrower, more specific claim than the generic 'connectivity expertise' most larger firms list |
| + | Works directly with semiconductor companies on SDK and driver development, closer to the chip than downstream product-firmware generalist work |
| + | Boutique size means the client-facing team is likely the same team doing the engineering, not separate sales and delivery layers |
| - | Small team (11-50, varying by source) limits capacity for programs needing several parallel workstreams |
| - | No public pricing tiers or minimum engagement figures for pre-qualification |
| - | Multi-protocol breadth within a small team means depth in any one protocol may be shallower than a single-protocol specialist |
| 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 |
