What Onix-Systems does

Onix-Systems is a custom IT services and software development firm founded in 2000 and headquartered in Kyiv, Ukraine, with distributed delivery teams across the United States, Europe, and Latin America. The company provides full-cycle software development — discovery, product strategy, UI/UX design, engineering, QA, and 24/7 support — across web, mobile, cloud-native, and AR/VR platforms, and has built a verticalized portfolio spanning travel and hospitality, healthcare, fitness and sports, EdTech, fintech, and online scheduling. Revenue is generated entirely through professional and managed services delivered via five engagement models: staff augmentation, dedicated remote teams, time and materials, fixed-price, and full-process development, with quote-based pricing.

The company's technical stack is anchored by AI integration and applied ML capabilities spanning computer vision (drone/satellite GIS, face recognition, deepfake detection), natural language processing (Rasa-based enterprise chatbots, sentiment analysis, language identification), generative AI (content and audio generation), predictive analytics, recommendation engines, and autonomous agents deployed across multiple production client platforms. Notable deployments include MisterB&B's travel platform (1M+ accommodations, 200 countries), the Cosmetics AI app (45K+ products analyzed, 100K+ users), and Digital Healthcare at Home (6 branded apps in market). The firm claims 100% AI-powered recovery workflows, an 82% client-return rate, 3+ year average retention, and 25+ years of delivery experience, and it markets a specialized software project rescue service.

Onix targets enterprises, mid-market firms, and SMBs globally through a hybrid inside-sales and field-sales motion, with marketing primarily driven by content (blog, SEO, case studies, testimonials) and analyst validation via B2B services marketplaces (Clutch, Techreviewer, GoodFirms, TechBehemoths). The company is privately held and founder-led (CEO Serhii Kholin, CTO Denis Sheremetov, CMO Anna Umanenko), with no disclosed external funding, acquisitions, or ownership changes across its 26-year history.
