American law firms bill an estimated $403.9 billion a year, most of it by the hour, at rates that now reach about $3,400 an hour for a top partner at a large firm, more than double the top rate of a decade ago. Investors have spent the past 18 months pouring money into the software side of that market, with Legora valued at $8.8 billion and Harvey at $15.6 billion, yet the two together still bill only about 0.1% of what law firms earn.
The bigger prize is the legal work itself, which is where a new group of AI-native law firms that sell finished work at fixed prices has raised at least $111 million in 13 months (our calculation). Commercial real estate is one of the busiest places to compete for that work, since about $2.5 trillion of US commercial mortgages fall due between 2025 and 2027 (our arithmetic) and every refinancing or sale needs loan documents, diligence and a closing.
Athena, an AI-native legal service for commercial real estate investors founded by former Legora staff, raised a $2.5 million pre-seed round on 3 November 2026 led by a16z Speedrun, the Andreessen Horowitz accelerator that admitted fewer than 0.4% of applicants into its latest cohort. In the two months since launch the San Francisco company has signed 22 clients at fixed fees that typically run 30% to 50% below what those clients paid on recent deals, while its mix of AI agents and attorneys cut review time by more than 70% in the first six weeks.
Legal Services and Legal AI in 2026
Law firm revenue has grown only about 1.4% a year over the past five years to an estimated $403.9 billion in 2025, which leaves room for a faster and cheaper model to take share. The two largest legal AI companies sell software into that market, with Harvey's annual recurring revenue above $400 million and Legora growing from $1 million to $100 million in under 18 months, a scale that still leaves both far smaller than the firms they sell to and shows how much larger the market for finished legal work is than the market for legal software.
Investors are paying up for the companies leading the software side. Legora, where Athena's founders met, raised a $550 million Series E at an $8.8 billion valuation on 21 October 2026, about 13 times the roughly $675 million it was valued at in May 2025 (our arithmetic). Harvey raised $550 million at $15.6 billion in September, which puts the two at $24.4 billion combined. Legora's reported rounds add up to about $1.4 billion raised to date (our arithmetic), which gives its alumni a close view of what law firms will and will not change once AI arrives.
The Billable Hour Nightmare and Big Law
Most of that $403.9 billion is still billed by the hour, at rates that keep climbing. A top partner at a large US firm now charges about $3,400 an hour, more than double the roughly $1,500 that drew criticism about a decade ago, while partner rates at the 50 largest firms rose 16% on average over the past year and Susman Godfrey's top partners moved from $3,000 to $4,000 an hour for 2026.
Across the wider market, average partner rates rose 5.1% in 2025, the joint second-largest rise since its tracking began in 2013, while firms with more than 750 lawyers handled 52% of matters. The hourly model creates an awkward incentive for AI, because a firm that uses software to turn ten hours of work into two loses eight billable hours, which at $3,400 an hour cuts a $34,000 bill to $6,800 (our arithmetic), whereas Athena's fixed fee means faster work improves the economics for both the firm and a client completing 10 to 15 acquisitions a year.
The Commercial Real Estate Refinancing Wave
Commercial real estate is about to generate a large volume of exactly this kind of legal work. The US carries $5.0 trillion of commercial and multifamily mortgages, with $957 billion scheduled to mature in 2025, $875 billion in 2026 and $652 billion in 2027, or about $2.5 trillion over three years (our arithmetic), including 30% of hotel loan balances and 23% of industrial balances that come due this year.
Many properties bought in 2021 and 2022 were financed with three-to-five-year loans that are now reaching maturity. Athena's founders expect that refinancing pressure to push more buildings to change hands. Investment is already rising, with US commercial real estate investment forecast to reach about $605 billion in 2026, a 16% increase on 2025, while some of Athena's clients submit dozens of offers for every deal they close, so every day saved after a property goes under contract matters.
How Athena Works
For a client, working with Athena feels like working with a traditional law firm, since the client sends documents to an attorney and receives legal work back. Behind the scenes, Athena's agents check each new agreement against the agreed deal terms, spot inconsistencies and prepare redlines, which are the marked-up edits lawyers send back and forth. They also draft the client emails that go with those edits while drawing on earlier transactions to learn each client's negotiating preferences.
Legal services are provided by Athena Circle, an affiliated law firm whose attorneys review the agents' output, make every legal decision and approve all work before it is delivered. The firm advises on commercial real estate acquisitions, sales and financing, covering purchase agreements, due diligence, loan documents and closings, while the firm's corporate practice also covers M&A and venture financing, led by founding attorneys Karen Abesamis, a former Morgan Lewis partner, with Juan B. Soto, formerly counsel at Lowenstein Sandler.
The early numbers show the model working at deal speed. On one early transaction the team turned around a purchase agreement in under 48 hours, which the client said was the fastest it had experienced, while L. Miguel Arce, chief executive of the Texas multifamily investor Mox, has praised the way the system learns from every deal, from the edits attorneys make to the preferences his team holds.
Founder Thesis
Cem Ucan, Athena's co-founder and chief executive, spent years in Big Law, at one point billing 3,000 hours a year, before moving into legal innovation at Baker McKenzie and then joining Legora as a founding legal engineer in 2024. At Legora he saw both the potential of AI and the limits of selling it to firms that earn money by the hour, which is the problem Athena is designed around.
Kieran John Keenan, co-founder and chief technology officer, studied law before building an automated legal reasoning system at his own startup, then joined Legora as its founding evaluations engineer, where he built the systems that test and improve AI performance across drafting, research and agentic workflows. That background shapes how Athena measures itself.
The idea for Athena took shape when Keenan built a prototype that could turn hundreds of documents into a first-draft due diligence report, the summary of risks a buyer reviews before closing. José Braz, who developed Legora's legal research agent and its broader research capabilities, then joined as founding engineer. Together, Keenan and Braz built the end-to-end deal platform that Athena runs on today.
Investor Thesis
Troy Kirwin, the a16z partner who has led Speedrun cohorts since the program's first batch, invests at the earliest stage in AI-native companies. Before joining Andreessen Horowitz he led more than 20 acquisitions on Unity's corporate development team, including Parsec and ironSource, after starting his career in investment banking at Jefferies, which gives him a buyer's view of which business models hold value as they scale.
Kirwin's case for Athena is that clients will keep wanting experienced professionals who take responsibility for the work even as AI becomes more capable, so the winning model pairs a system that improves through real legal work with attorneys who stand behind every deal. Speedrun, launched in 2023 as a gaming-focused program and now open to startups of any type, accepts fewer than 1% of applicants overall, which makes a lead check from the program a strong early signal for a two-month-old firm.
The round also places Athena in a fast-growing group of AI-native law firms that sell finished legal work at fixed prices. Crosby raised $20 million in October 2025 and a $60 million Series B in April 2026, while General Legal raised $11.5 million in its first three months for contract work priced at $500 per agreement. Arceus Legal followed with $17 million in October 2026 in a round led by Greycroft, which brings the five rounds including Athena's to at least $111 million in 13 months (our arithmetic). Most of that group focuses on commercial contracts, while Athena is aiming at complex, high-value property transactions.
Outlook For 2027
Athena plans to grow from commercial real estate into other property types and geographies before moving into wider transactional law, with the long-term aim of shrinking legal timelines from weeks and months to minutes and hours. Its founders describe the goal as freeing a 21st-century economy from a 19th-century way of delivering legal work.
The timing works in its favor, because the refinancing wave will send a steady flow of loan documents, diligence and closings through the market at the same moment that investors are pouring billions into legal AI. Athena's first two months show that clients will move their deals to a firm that prices work upfront and delivers it faster. The $2.5 million round gives the team the room to prove that the model holds as deal volume grows.
