What Existek does

Existek is a private offshore software development services company founded in 2012 by Oleg Feferman, operating three delivery centers in Vinnytsia (Ukraine), Warsaw (Poland), and Bucharest (Romania). The company sells two main commercial lines: staff-augmented dedicated development teams billed on multi-year contract cadences, and full-cycle custom software development across web, mobile, desktop, ERP, AI, and embedded systems. Technology coverage spans .NET, Java, React, Angular, Node.js, Flutter, Swift, Kotlin, and Objective-C, with integration exposure to Microsoft Azure, Google Firebase, Apple HealthKit, Android Health, DNN/DotNetNuke, and Windows Hello.

The company targets mid-market and enterprise customers, with disclosed engagements spanning oil and gas (Norwegian oilfield ERP), fintech (PeerWallet blockchain wallet), document management (IntelliChief), accessibility software (Lingit), management consulting, and industrial automation (The Carpenter Group water-treatment embedded module). Pricing is quote-based and not publicly disclosed; client acquisition is sales-led with consultation-driven requirements analysis and a 24-hour response SLA, supported by content marketing via an active blog, SEO, and Clutch/GoodFirms review profiles.

Revenue is generated through professional services (project-based) and managed services (dedicated team) streams. The firm is founder-owned with no disclosed external investors, funding rounds, or M&A activity since inception, and operates with a headcount in the 51-100 range. Recognitions include Clutch 'Top 2022 B2B Company in Romania' and repeated 'Top Ukrainian Software Developer' awards, alongside GDPR and COPPA compliance for privacy.
