Onit
About the company
Onit is a legal operations software company founded in 2011 in Houston by Eric M. Elfman and now headquartered in Atlanta, Georgia. It is private-equity-backed: K1 Investment Management has been its principal investor since committing $200 million in 2019. Michael Farlekas, formerly chief executive of the supply chain software company E2open, has led the business since March 2024, with Elfman moving to vice chairman of the board.
Onit has grown mainly through acquisition. It bought SimpleLegal in May 2019 immediately after the K1 investment, the New Zealand developer McCarthyFinch in 2020, Bodhala and the German e-billing vendor BusyLamp in 2021, and SecureDocs with its ContractWorks product in 2022. Under Farlekas the consolidation has continued with Legal Files in January 2025 and LawBase in December 2025, both serving government case management, while the lineup is rebuilt around an AI platform branded Unity.
Onit at a glance:

What legal teams should know: Onit is one of the larger consolidators in legal operations, giving buyers breadth across e-billing, matter and contract management but leaving overlapping product lines inherited from separate acquisitions. Customers should establish which named product a quotation covers and how it maps to the Unity platform. Private equity ownership since 2019 means the portfolio keeps changing.
