Lexis Solutions
Lexis Solutions develops AI-native products, intelligent data pipelines, and web applications for startups and scaling businesses across Europe and the US.
About
Lexis Solutions builds software designed from the ground up around AI — not bolt-on features added to existing systems. Based in Sofia, Bulgaria with offices in Los Angeles and Berlin, the team works with startups and scaling businesses across the EU, US, and beyond. Founded in 2017 after winning national startup awards at a university hackathon, they operate as a senior-led team of 10–49 people.
Their core work spans three areas: AI-native product development (agentic workflows, policy-aware retrieval, evaluation loops), intelligent data pipelines (scraping infrastructure, structured data APIs, permission-aware feeds), and the web and mobile interfaces that connect AI backends to end users. Clients include Onnoplus.com, Kreston Bulmar, and Finansi.bg — with documented outcomes including 210% sales growth and 250,000 users reached within a single year of launch.
