Existek

Existek is a full-cycle offshore software development company founded in 2012 with offices in Bucharest (Romania), Warsaw (Poland), and Vinnytsia (Ukraine). The company builds custom web, mobile, and desktop applications, enterprise integrations, and AI solutions across healthcare, fintech, manufacturing, eCommerce, logistics, and education sectors. Named client references include SparkYou Consulting, PeerWallet, IntelliChief LLC, Lingit, and Management Solutions 4U.

Services and capabilities

Existek offers three main engagement models: custom software development, dedicated development teams (DDC), and professional IT consulting.

For custom development, the company handles full-cycle projects including requirement analysis, architecture design, UI design, testing, maintenance, and support. They build enterprise applications (asset management, HR systems, inventory), mobile apps for iOS and Android, web applications, desktop software (Windows UWP, WPF), business intelligence tools, custom ERP systems, and AI-based solutions. On the technology side, they work with Node.js, .NET, Java, React, Angular, Objective-C, Swift, Kotlin, Flutter, React Native, C#, and related platforms.

The dedicated development team model allows clients to hire developers, QA engineers, project managers, business analysts, and UI/UX designers on a time-and-materials or monthly basis. Teams start from a single developer and scale up. Existek claims to reduce costs by up to 40% compared to hiring locally and cut development speed delays through the DDC model. The onboarding process takes 2–3 weeks from initial contact to active development. Full control is maintained through project management tools, daily meetings, and access to task tracking systems.

IT consulting covers technology assessments, codebase audits, and architecture recommendations. The company emphasizes involvement in full business process management and business intelligence implementation.

Notable work

For a major Norwegian oilfield service company, Existek delivered a web-based ERP application built on .NET and DNN. The system included general ledger, accounting, analytics, assets management, warehousing modules, and a field force management Android app. The project involved full-cycle business process management and business intelligence implementation.

For Lingit (assistive technology), a dedicated team worked for over 5 years on system maintenance and new functionality, helping the product reach 1+ million users. The company credits Agile methodology adoption with doubling development speed and reducing development costs by 63% through the offshore model.

Other delivered projects include Field Team (a hybrid Flutter sales force automation app for iOS and Android, sharing 90% of codebase), Fit Us (a native fitness application with Apple HealthKit and Android Health integration), and Smart Login (a Windows behavioral biometrics security application with a web admin panel).

How they work

Existek uses established project management practices focused on transparency and collaboration. Daily interactions, meetings, and detailed reports are standard. For dedicated teams, clients participate in hiring and interviewing candidates before assignment begins. The company's onboarding process is structured: contact → receive CVs → interview candidates → team starts work → manage and scale as needed. Payment terms are negotiated individually and can be fixed-price per hour or per resource per month. The team includes senior developers with 5+ years of experience. Project managers handle scope, scheduling, and risk; business analysts gather requirements and recommend solutions; QA engineers test in parallel with development.

Team and credentials

Existek operates across three main locations with offices in Poland, Romania, and Ukraine. The source does not specify total team size, but references "more than a decade-long experience" and indicates access to a broad specialist pool. Client reviews cite the team's technical expertise, reliability, and ability to adapt to project needs. One founder, Oleg, is mentioned by name in a client testimonial from Just Make It Work. The company has a 4.9/5 rating based on 17 client reviews on an unspecified platform (likely Clutch or similar).
