Lexroom Acquires Bulgarian Legal-Tech Startup Praven Intelekt

Italian legal-tech company Lexroom has bought Bulgarian startup Praven Intelekt in full, giving it a first foothold in Central and Eastern Europe. The deal also marks Lexroom’s entry into Bulgaria, after earlier expansions into Germany and Spain.

Praven Intelekt built an AI platform for Bulgarian law in little more than a year. The startup says it has more than 20,000 registered users, over 900 customers, around 1,500 weekly active users, and access to nearly 1.2 million legal documents drawn from 18 official Bulgarian and European sources.

That local depth is the point. Lexroom’s co-founder and CEO Paolo Fois said the company chose Praven Intelekt for its team, its traction, and the product’s focus on Bulgarian legal professionals. He also argued that legal AI cannot just be copied from one country to another with translation alone. It needs local legal data, jurisdiction-specific knowledge, and a sense of how people actually work.

Praven Intelekt was founded in 2025 by Siyanna Lilova, Rangel Milushev, and Christian Tsanov. Lilova will become Head of Central and Eastern Europe at Lexroom, where she’ll lead regional growth. The Praven Intelekt team will join Lexroom, and its technology, datasets, and local expertise will be folded into Lexroom’s platform over time.

Lexroom itself was founded in 2023 and now says it serves more than 20,000 customers, employs over 200 people, and has built its product on more than 13 million legal sources. In summer 2026, it passed €20 million in annual recurring revenue. Then in May 2026, it raised a $50 million Series B led by Left Lane, bringing total funding to more than $73 million. Its ambition is broad: one platform for legal research, drafting, document analysis, and other professional workflows.
