Lexis Solutions

Lexis Solutions is a software and AI development company based in Sofia, Bulgaria. It builds AI agents, knowledge assistants and the products around them, and it also delivers conventional web and mobile applications. The firm lists a partner status in the Claude Partner Network.

Its AI work covers agentic workflows, retrieval with source tracking, evaluation after launch, and voice and multimodal interfaces. Its data services cover scraping infrastructure, data pipelines and APIs that feed search tools, dashboards and internal systems. The engineering stack centres on React, React Native and Node.js.

Published case studies show the range. For a construction company, the team built a governed assistant that answers business questions with warehouse-backed SQL, in place of a queue of reporting tickets. For a Bulgarian financial data platform, it built a retrieval system on Anthropic Claude that extracts key figures from millions of company documents. It also built a CRM product for a client in the sales sector.

Lexis Solutions works with startups, scaling businesses and larger organisations. Clients can hire dedicated teams of developers, DevOps engineers and project managers who work inside the client's own process. The chief executive and co-founder is Deyan Denchev.
