“The legal profession, often characterized by a reverence for tradition and resistance to change, is at the cusp of a technological revolution that promises the potential to reshape the profession," says Haley Sylvester, Associate at Pryor Cashman.
I realize it's still 2025, but the legal tech startups shaping 2026 and beyond are already doing big things. Our industry shows no sign of slowing down: According to Precedence Research, the global legal technology market is projected to grow from $29.81 billion in 2025 to approximately $65.51 billion by 2034, registering an impressive 9.14% annual growth rate.
The following 10 US-based legal tech startups were all founded over the last decade, each led by visionary founders making an impact on the legal industry. Keep your eye on them as we move into next year.
1. Darrow
Founded: 2020 CEO: Evyatar Ben Artzi
Focus: AI-powered legal intelligence
CEO Evyatar Ben Artzi co-founded Darrow in the wake of the pandemic along with co-founder Gila Hayat, Chief Technology Officer, with the intention of empowering plaintiff firms to use technology to proactively uncover high-value legal violations that might otherwise go unnoticed.
Darrow scans and clusters vast amounts of public records to spot potential class-action lawsuits and mass tort opportunities in areas like data privacy, antitrust, medical liability, ERISA, environmental law, amongst others. The company's in-house legal experts and legal intelligence analysts analyze all data and potential violations to ensure accuracy and legal merit before cases are brought forward. The company partners with plaintiffs’ attorneys across the US to litigate these cases, while also managing a complete plaintiff-connection and intake service, too.
Over the past year and a half, Darrow has expanded its offerings: attorneys have access to an AI-powered newsfeed of legally relevant stories tied to potential violations for simplified research, as well as anonymized previews of high-signal matters that attorneys can evaluate and request. In addition, Darrow offers a complete case valuation service, including projected settlement ranges, potential class size, and estimated plaintiff recoveries. The company also offers services for in-house counsel teams.
Headquartered in Tel Aviv and New York City, Darrow has raised $35 million in a Series B round in 2023, bringing its total funding to nearly $60 million to date. Led by Georgian, investors include F2 Venture Capital, Entree Capital, NFX, and Y Combinator.

The software builds a document graph of case evidence, using specialized language models plus a human verification process to ensure accuracy to speed up and simplify processes.

Harvey’s AI can answer legal questions, draft documents, and perform research by understanding legal context. The platform integrates directly with document management systems and email so lawyers can query large volumes of documents and surface relevant precedents in seconds.
In late 2022, Harvey received $5 million in seed funding led by the OpenAI Startup Fund, with investors including AI leaders like Google’s Jeff Dean. By July 2024, Harvey had raised a $100 million Series C round at a $1.5 billion valuation led by GV, with Sequoia, Kleiner Perkins, and OpenAI as participants.

In its first year, Paxton saw rapid adoption, reporting a 14× growth in monthly recurring revenue and an 8× increase in active users over a nine-month span. This momentum helped Paxton secure a $22 million Series A funding in early 2025 led by Unusual Ventures, bringing its total funding to $28 million so far.

Law Firms Investing in Legal Tech Startups
As legal tech continues to attract investor interest, some of the world's most prominent law firms are stepping into a new role; not just as customers, but as backers and builders of legal tech startups or launching their own incubators and innovation hubs.
Allen & Overy, for example, was a pioneer in this space with its Fuse tech innovation hub, launched in 2017 to house startups working on legal, regulatory, and dealtech solutions. Now part of the newly merged A&O Shearman, the Fuse program continues to serve as a gateway for legal tech startups to test and validate their products in legal environments. The program has housed companies like Harvey and Avvoka, giving them direct access to feedback from practicing attorneys.
Cooley LLP, a major player in tech and venture law, has also established itself as a key legal tech investor. Through its Cooley GO platform, the firm has provided startup resources and guidance, while simultaneously participating in funding rounds for promising legal tech ventures. Its work with venture-backed startups positions it to spot emerging trends and capitalize on them early.
Other firms including Morrison Foerster, Wilson Sonsini, and Latham & Watkins have also been linked to legal tech investing through advisory roles, accelerator partnerships, or venture initiatives.
