Sirin Software vs Capgemini Engineering: overview
Sirin Software
Sirin Software, founded in 2014, is headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine — a deliberate US-front, Ukraine-delivery structure that gives American buyers a single US contracting entity while the actual engineering work happens at Ukraine's substantially lower cost base. This structure is common among boutique outsourcing firms and worth understanding explicitly: the client relationship and invoicing run through the US entity, while day-to-day engineering is offshore.
Capgemini Engineering
Capgemini Engineering traces to Altran Technologies, founded in 1982 in France, which Capgemini acquired in 2019 and rebranded in 2021. Now employing an estimated 45,000-52,000 people worldwide, this is one of the largest global outsourcing vendors on this list by headcount, with a correspondingly global delivery footprint — but embedded engineering is one technical domain within an extremely broad portfolio, and buyers should confirm which pre-2019 Altran teams remain intact.

|---|---|
| + | US-based contracting entity simplifies invoicing and legal terms for American clients while engineering is delivered offshore at lower cost |
| + | Named depth across six wireless protocols (Wi-Fi, BLE, Matter, UWB, NFC, LoRaWAN) reduces the need to outsource each protocol to a different specialist |
| + | Staff augmentation is offered explicitly, useful for buyers wanting to extend an existing in-house team with offshore capacity |
| - | Small team (11-50, varying by source) limits capacity for large outsourcing programs needing many parallel engineers |

| + | 40+ year engineering consulting heritage predating the 2019 Capgemini acquisition and 2021 rebrand |
| - | Rebranded from Altran in 2021 after the 2019 Capgemini acquisition — confirm directly which legacy Altran teams remain intact |
| - | Embedded/electronics engineering is one technical domain within an extremely broad portfolio, not a dedicated outsourcing specialty |
| - | Scale and process overhead of a firm this size is a poor fit for small, fast-moving outsourcing engagements |
