Following the recent announcement of a record-setting $900 million investment in a leading law practice management company, this publication endeavored to compile a comprehensive listing of the largest private investment rounds in legal technology. This compilation seeks to expand upon initial reports to provide a more accurate and detailed account of the sector’s most significant financial milestones.
Gathering this information presents inherent challenges, and Human&Legal acknowledges that this list is a working document. It is the publication’s hope to refine this data through community input. Readers are encouraged to share any missing deals or corrections to the listed entries to ensure the accuracy of this historical record. As updates are received that result in companies being ranked lower, they will be kept on the list, allowing the final count to exceed the original twenty-five.

Boundary Cases and Unconfirmed Data
It is important to define the scope of “legal tech” for the purpose of this analysis. This list deliberately omits certain companies considered “legal tech adjacent.” A notable omission is DocuSign, which, despite its relevance to legal workflows, is not strictly classified as a core legal technology provider for this compilation. If included, DocuSign would have appeared twice on this list for its $303.29 million raise on October 30, 2015, and its $115 million raise on October 27, 2024.
Other companies left off due to their adjacent nature include Zenwork, which secured $163 million on November 9, 2021, and Quantstamp, which raised $137 million on April 1, 2022.
Furthermore, a reported $204 million raise for Litera in 2022 was noted but could not be confirmed for inclusion at the time of publication.
Human&Legal encourages readers with verifiable information on other significant investments to submit them for consideration and inclusion in future updates to this important industry metric.
