Lexroom, an Italian legal AI company, announced on 8 September 2026 that it had acquired Query Juriste, a French startup that runs an AI legal research platform for lawyers. Lexroom took 100% of the company. It announced a second purchase at the same time, Bulgarian legal technology company Praven Intelekt, and described the pair as its first acquisitions since it was founded.
Terms were not disclosed. Lexroom did not give a price for either company or say how the deals were paid for.
Query Juriste's founders and team are joining Lexroom. Co-founder Etienne Le Guay will lead Lexroom's development in France, and the Query Juriste brand will be phased out over time in favour of the Lexroom name, according to Tech.eu.
What Query Juriste built
Query Juriste was founded in Paris in 2024 by Etienne Le Guay, Emile Lombardo and Maxence Mortagne, according to Pulse 2.0. Its product searches French and European legal sources, analyses the material and produces structured research reports for lawyers and in-house legal teams.
Lexroom said the platform is connected to more than five million French and European legal documents, which Pulse 2.0 reported are drawn from 18 official sources and kept continuously updated. At the time of the deal Query Juriste had nearly 300 customers and around 1,000 paying users. Pulse 2.0 named the law firms Bredin Prat and De Pardieu Brocas Maffei among its clients.
Le Guay said the company had been built on the idea that AI only helps lawyers when it is grounded in the underlying legal data. He told Startupbusiness that the team joined Lexroom because it was founded on the same "data-first" principle.
“These acquisitions are a major milestone in our European expansion, and only the beginning.”
Why Lexroom is buying
Lexroom sells a legal AI platform built on its own infrastructure of certified legal sources, which it says now covers more than 13 million documents. Its long-term aim, Tech.eu reported, is to become the AI operating system for legal work, starting with Europe's civil law countries.
Legal research tools depend on national case law and legislation, so each new country normally means building a new data layer. Buying companies that have already done that work in France and Bulgaria lets Lexroom skip that step. Co-founder and chief executive Paolo Fois put it directly: "It doesn't make sense to reinvent the wheel market by market."
With the two deals Lexroom says it now operates in five European markets: Italy, Germany and Spain, which it entered on its own, plus France and Bulgaria. The two acquisitions together add about 1,200 customers. Praven Intelekt, founded in Sofia in 2025, brings more than 900 customers, and its co-founder Siyanna Lilova becomes Lexroom's head of Central and Eastern Europe.
Praven Intelekt was founded in Sofia in 2025 by Lilova, Rangel Milushev and Christian Tsanov. Pulse 2.0 reported that it has more than 20,000 registered users and about 1,500 weekly active users, and that its research tool draws on about 1.2 million documents from 18 official Bulgarian and European sources. Lilova said joining Lexroom would let the team "preserve that local depth while operating at a completely different scale."
The buyer and its funding
Lexroom was founded in 2023 by Paolo Fois, Martina Domenicali and Andrea Lonza. It reports more than 20,000 customers and more than 200 employees, and said it passed €20 million (about $23 million) in annual recurring revenue in summer 2026.
In May 2026 it raised a $50 million Series B led by Left Lane, with Base10 Partners, Eurazeo, Acurio Ventures, Entourage and View Different taking part. That round came eight months after a $19 million Series A and took total funding above $73 million, according to Tech.eu.
Query Juriste, by contrast, had not raised outside capital. Pulse 2.0 described the company as bootstrapped.
A rare deal in European legal tech
Artificial Lawyer noted that acquisitions by EU-based legal tech startups are still uncommon, pointing to Legora and Germany's Noxtua as the main earlier examples of European players expanding by buying rather than building.
Fois said the two deals were not the last. "These acquisitions are a major milestone in our European expansion, and only the beginning," he said in the company's announcement.
