DB2 Limited

DB2 Limited is a software engineering team working from Kyiv, with a presence in New York, that acts as an outsourced technical partner for startups. It started as a mobile and web development company and now centres on architecture, AI integration and scaling products, with clients owning all the code it writes.

What DB2 Limited offers

• CTO as a service — architecture, UX and UI design, development, DevOps and tech-stack decisions for startups without a senior technical lead.
• Tech and AI audit — interviews with teams, a review of the codebase and workflows, and a prioritised roadmap of fixes and automation opportunities.
• AI agents and language model integration — custom AI workflows, retrieval systems and vector databases built into a product.
• Rapid MVP builds — launching a core product in three to six weeks using ready-made modules.
• High-load platforms — multi-tenant SaaS back ends, APIs and databases built to scale, with monitoring.
• Code rescue — taking over failed or messy projects, refactoring and shipping them.

Who it works with

The team mainly serves startup founders. Past projects include live-event and IoT systems for a Samsung project, an AI recognition engine with a CRM, and algorithmic trading infrastructure.
