Sirin Software vs Klika Tech: 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.

Klika Tech

Klika Tech, founded in 2013 and headquartered in Lubbock, Texas with roughly 180 employees, maintains locations across the Americas, Europe, and Central Asia — a genuinely multi-region delivery footprint that lets outsourcing buyers choose a preferred cost/timezone combination rather than being locked into one country. AWS Premier Partner status for IoT and edge-to-cloud solutions is a checkable qualification for buyers specifically outsourcing an AWS-native architecture.
