One of two Bulgarian companies among 331 partners in Anthropic’s directory.
Lexis Solutions has achieved the Select partner tier in the Claude Partner Network Services Track. The Sofia-based software company builds AI agents, AI integrations and data systems for companies in Germany, the UK, the US and Finland.
The Claude Partner Network is how Anthropic works with the firms that put Claude into production for customers. The Services Track recognises partners for building a certified delivery team, delivering Claude use cases for clients, and proving the work through public customer references. As of October 28, 2026, Anthropic’s partner directory lists 331 partners worldwide, and only two of them are Bulgarian companies.
As of October 2026, 90 per cent of Lexis Solutions’ engineers hold the Claude Certified Architect – Foundations certification.
The company’s recent work shows the kind of production systems the tier reflects, such as Barton Malow, a large US construction company, where an internal data assistant was rolled out across the whole organisation. On real business questions, it gave better answers than the native NL2SQL tool in 62 per cent of cases.
At Finansi.bg, a Bulgarian financial data platform, a pipeline built on Claude extracts structured financial data from more than two million company reports. Fewer than 8,000 documents needed manual review, and the estimated processing cost fell from about two million euros to 18,000 euros.
At OnnoPlus, a German review-management business, a custom AI-first CRM includes a tool that uses Anthropic’s models to help lawyers draft review-removal complaints.
“Engineering teams in Central and Eastern Europe have built software for Western companies for years. AI agents are the next step in that work, and Bulgarian teams are ready for it. We are proud to be one of the two Bulgarian companies in the Claude Partner Network, and we want to see that number grow,” said Deyan Denchev, CEO and co-founder, Lexis Solutions.
Founded in 2017, Lexis Solutions works with start-ups, scale-ups and mid-sized companies on AI agents, generative AI integrations, web scraping and data processing, and custom web and mobile development. Its Select tier is listed in the Claude partner directory.
