Filevine's Legal Operating Intelligence System, branded LOIS, layers a set of AI agents across a firm's entire caseload — drafting documents, extracting deposition intelligence, building medical-record timelines, and automating client intake — on top of Filevine's underlying case-management platform.
Rather than building on general-purpose internet-trained models, Filevine emphasizes a proprietary "purpose-built legal graph" trained on more than 40 million matters processed on its platform. The company, founded in 2014/2015 and headquartered in Salt Lake City, Utah, markets itself across the full range of firm sizes — solo practitioners through Big Law — as well as government agencies (prosecutors, public defenders, federal) and in-house legal departments.
Filevine has raised roughly $626M total, including a $400M Series E in 2025 (Accel, Halo Fund, Insight Partners), at a reported $3B valuation.
Pricing is not officially published; third-party reporting places core case-management around $50-75/user/month, with document-automation add-ons around $75-100/user/month and onboarding fees ranging from $1,000 to over $10,000.
