Use cases
What you can produce with Eve
- Incoming calls answered, leads scored and retainer signing started by an AI intake voice agent
- Medical chronologies and treatment summaries built from hundreds of pages of records and bills
- Demand letters, discovery requests and discovery responses drafted from the case file
- An overnight audit of every active matter flagging missed injuries, treatment gaps and next steps
- Plain-English answers about firm revenue, margins and settlement pacing from Eve Analyst
- Trial preparation support across a matter's documents
Eve is the most heavily funded tool built only for plaintiff firms, and its scope now runs from answering intake calls to discovery responses, overnight case audits and firm revenue analytics. For document-heavy personal injury and employment practices, that breadth in one vendor is the appeal.
It is US-only in law and process, pricing is by sales call, and growth and settlement figures come from Eve itself. Every filing drafted with it still needs citation checking by an attorney. Little direct relevance for ASEAN firms.
What we found
Eve is legal AI built only for plaintiff-side law firms in the United States: personal injury, employment, workers' compensation, Social Security disability and medical malpractice practices. It is run by Butler Labs, Inc., doing business as Eve Legal, a San Francisco company that Fortune says Jay Madheswaran, Matt Noe and David Zeng started in 2020. The Eve assistant itself launched in October 2023.
The product has grown from a drafting assistant into what Eve calls EveOS. It covers intake, including an AI voice agent that answers calls and scores leads; medical chronologies built from records and bills; demand letters; propounding and responding to discovery; trial preparation; and outbound case communications. A January 2026 launch added Agents that carry out routine work, an Auditor that reviews every active matter overnight for missed injuries or treatment gaps, and an Analyst that answers questions about a firm's revenue and settlements. Eve's press page records EveOS, with Analyst and the Atlas data layer, reaching general availability in August 2026.
The funding is well documented. Eve raised a $47 million Series A led by Andreessen Horowitz in January 2025, then a $103 million Series B at a valuation above $1 billion in September 2025, led by Spark Capital with Andreessen Horowitz, Lightspeed and Menlo Ventures. It reported more than 450 customer firms at that point; its homepage now claims over 1,700. Those are company figures, as is the settlement uplift its homepage calculator promises.
Pricing is not published; firms book a call. A G2 score shown on Eve's homepage was not read on G2 and is left out, as are reviewer patterns that could not be counted and a 2026 Louisiana court report that could not be read in the original. As with any legal AI, Eve's drafts need an attorney's check before they reach a court.
