Sirin Software vs Timesys: 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.
Timesys
Timesys Corporation, founded in 1996 and headquartered in Pittsburgh, Pennsylvania, is a US-onshore embedded Linux security and long-term maintenance specialist with roughly 60 employees. In December 2023, Lynx Software Technologies acquired Timesys; outsourcing buyers evaluating the company should confirm current organizational continuity directly, since ownership transitions are exactly the kind of thing due diligence should verify rather than assume from the historical brand.
