Sirin Software vs Promwad: 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.

Promwad

Founded in 2004 and headquartered in Essen, Germany, Promwad runs additional engineering centers in Latvia and Serbia — both established nearshore-Europe delivery hubs offering lower engineering cost than Western Europe while remaining EU-adjacent (Latvia is an EU member; Serbia is an EU-accession candidate with strong engineering talent at competitive rates). This multi-country nearshore structure lets Promwad offer German-market client-facing presence with Baltic and Balkan delivery cost.
