Legora sells AI software that law firms and corporate legal departments use to research law, review large document sets and draft legal work. The company is in talks to raise at least $300 million at a roughly $8.5 billion pre-money valuation, Investing.com reported, citing Bloomberg and people familiar with the effort.

The discussions remain preliminary, and terms could change. The reported price compares with a $5.6 billion valuation five months earlier, after a $50 million April extension brought Legora’s Series D to $600 million. Legora had announced the round’s initial $550 million close at a $5.55 billion valuation on March 10.

One part of the platform turns document review into a table. A legal team can import files from its document-management system, internal repository or virtual data room; Legora places each document in a row and the team’s prompts in columns. Reviewers can open a cell’s source document and reasoning, collaborate with colleagues and lock completed work.

The research product is built around checking an answer, not just generating one. Legora says lawyers can open the passage behind a finding and inspect its supporting primary law. The software also weighs sources by legal authority, checks that they remain valid and searches across multiple jurisdictions.

Legora says more than 100,000 legal professionals at over 1,500 law firms and in-house legal teams use the platform across more than 50 markets. The company has named White & Case, Cleary Gottlieb, Linklaters and Deloitte among its customers.
