Investors poured nearly $6 billion into legal tech in 2025. Harvey is valued at $11 billion. Legora just tripled its valuation to $5.55 billion. And new startups are launching every month with tools built specifically for lawyers.
If you are running a law firm and still figuring out where AI fits into your practice, this list will help.

1. The Lawyers’ Marketer
Focus: AI-powered marketing built exclusively for law firms
Website: lawyersmarketer.com
Most legal AI startups are focused on what happens after you sign a client. Research, contracts, document review, billing. That is all important, but none of it matters if you do not have a steady flow of clients walking through the door.
That is where The Lawyers’ Marketer comes in.
We are not a generic marketing agency that happens to take on law firm clients. We built our entire operation around law firm marketing, and we use AI to do it better and faster than anyone else in the space. Our team leverages AI tools to build SEO strategies, create high-converting content, run smarter PPC campaigns, and analyze your intake process from top to bottom.
Here is what makes this different from just hiring someone who “does SEO.” We understand how legal keywords work, what bar associations require, and why the path from click to signed case is not as simple as most agencies make it sound. We have built tools like our law firm marketing calculator to give firms real numbers instead of vague promises.
If you are investing in AI for legal research and document review but still running your marketing the old way, you are leaving cases on the table. Learn more about our approach or check out our complete guide to legal AI for law firms.
Best for: Any law firm that wants more cases and better clients without wasting money on marketing that does not work.
2. Harvey
Focus: AI platform for legal research, contract analysis, and litigation support
Harvey is the biggest name in legal AI right now, and for good reason. The company just raised $200 million at an $11 billion valuation, making it one of the most valuable AI startups in any industry, not just legal.
Harvey builds AI tools that help lawyers with contract analysis, compliance, due diligence, and litigation. The platform is used by more than half of the 100 largest law firms in America. It integrates directly with document management systems and email, so lawyers can query huge volumes of documents and pull up relevant precedents in seconds.
The company was founded in 2022 by Winston Weinberg and Gabe Pereyra, and it reached $100 million in annual recurring revenue within three years. That kind of growth in legal tech is unprecedented.
Best for: BigLaw and large firms with enterprise budgets. Pricing starts at $1,000+ per lawyer per month with seat minimums.
3. Legora
Focus: Collaborative AI workspace for law firms
Formerly known as Leya (and Judilica before that), Legora just raised $550 million in a Series D round led by Accel, tripling its valuation to $5.55 billion. The company is headquartered in New York after going through Y Combinator’s winter 2024 batch.
Legora’s platform lets lawyers automate repetitive tasks while pulling from both public legal sources and their own internal data in one place. It is built for the full workflow: research, document review, drafting, and case analysis. The company now serves over 800 law firms and legal teams worldwide.
What separates Legora from Harvey is its focus on collaborative workflows and its roots in the European market, which gives it a broader international perspective on legal AI.
Best for: Mid-size to large firms that want a collaborative AI workspace. Expanding aggressively in the U.S. with new offices in Houston and Chicago.
4. Clio
Focus: Cloud-based practice management with built-in AI
Clio is not technically a startup anymore. The company has been around for over 17 years and serves more than 150,000 legal professionals across 130+ countries. But their AI features are new enough and impactful enough to earn a spot on this list.
Clio’s AI tools are built directly into their practice management platform. They automate tasks like extracting deadlines from court documents, generating billing drafts, creating performance reports, and summarizing case files. Every AI action includes review checkpoints so the lawyer stays in control.
The company raised massive funding rounds totaling $850 million in 2025 (on top of $900 million in 2024), and recently merged with vLex to create what some are calling the first “full-stack” legal technology engine.
Best for: Small to mid-size firms that want AI baked into their practice management software. Plans start around $89 to $149 per month.
5. EvenUp
Focus: AI for personal injury law firms
If you run a personal injury practice, EvenUp is worth a close look. The company builds AI specifically for PI lawyers, handling demand letters, medical chronologies, and case preparation.
EvenUp raised a $150 million Series D led by Bain Capital Ventures, and the tool is designed to do the heavy lifting on the documentation that eats up so much time in personal injury cases. Instead of spending hours assembling medical records and drafting demand packages, attorneys can let EvenUp handle the grunt work and focus on case strategy and client relationships.
Best for: Personal injury law firms of any size. The ROI math works especially well for high-volume PI practices.
6. CoCounsel (by Thomson Reuters)
Focus: AI-powered legal research assistant
CoCounsel started as Casetext, which Thomson Reuters acquired in one of the first major AI exits in the legal space. Now it lives inside the Westlaw ecosystem, which gives it access to one of the largest legal databases in the world.
CoCounsel uses natural language processing to understand the context of your research queries and surfaces relevant case law, statutes, and regulations. Its CARA AI feature can review uploaded briefs and identify case law you might have missed.
For firms already paying for Westlaw, adding the CoCounsel AI tier is probably the path of least resistance to getting started with legal AI.
Best for: Litigation-focused firms, especially those already in the Thomson Reuters ecosystem. Plans start around $225 per month.
7. Spellbook
Focus: AI contract drafting and review
Spellbook is built specifically for transactional lawyers who spend their days in contracts. The tool works inside Microsoft Word and helps with drafting, review, and negotiation.
What sets Spellbook apart is its narrow focus. It is not trying to be everything to everyone. It does contracts, and it does them well. The AI can suggest edits, flag risks, and help standardize language across your firm’s agreements.
Best for: Transactional law firms and in-house legal teams that handle high volumes of contracts.
8. Darrow
Focus: AI-powered legal intelligence for plaintiff firms
Darrow takes a completely different approach from most legal AI startups. Instead of helping lawyers work on existing cases, it helps plaintiff firms find new ones. The platform uses AI to proactively uncover high-value legal violations that might otherwise go unnoticed.
Founded in 2020 by Evyatar Ben Artzi and Gila Hayat, Darrow essentially acts as a case origination engine. It scans for patterns of corporate misconduct and connects plaintiff attorneys with potential claims.
Best for: Plaintiff law firms looking for a competitive edge in case acquisition.
9. Filevine
Focus: Legal operating platform with AI-powered case management
Filevine provides an all-in-one platform that covers case management, document organization, and lead intake. Think of it as the central nervous system for your firm’s operations.
The company raised $260 million in 2025, and its AI features are designed to help legal teams manage the entire client lifecycle in one place. That includes everything from initial intake to final resolution.
For firms that are interested in automating their workflows, Filevine is one of the more comprehensive options out there.
Best for: Mid-size firms that want case management and AI in a single platform.
10. Eve
Focus: AI for plaintiff litigation automation
Eve builds an AI platform specifically for plaintiff law firms that automates the entire litigation process. The software handles tasks from client intake and medical record summaries to drafting discovery and motions.
If you are running a plaintiff practice and spending too much time on the administrative side of cases, Eve is designed to take that burden off your team so attorneys can focus on what actually moves the needle.
Best for: Plaintiff law firms that want end-to-end litigation automation.
11. Ironclad
Focus: AI-powered contract lifecycle management
Ironclad manages the full contract lifecycle, and it works across legal, sales, procurement, and other departments. That makes it a strong choice if your firm or your corporate clients need a solution that fits into a broader business technology stack.
The platform allows you to analyze contracts, report on data, centralize review processes, and enforce drafting guidelines. It is more of an enterprise play than a pure law firm tool, but for firms that work closely with corporate clients, it can be a valuable piece of the puzzle.
Best for: In-house legal teams and firms with heavy corporate contract work.
12. Lawmatics
Focus: AI-powered CRM, intake, and marketing automation for law firms
Lawmatics recently launched a suite of AI tools that bring agentic automation to legal lead intake. The platform can qualify leads, engage prospects, and manage operations automatically.
For firms that are focused on the business side of running a practice (and you should be), Lawmatics fills a gap that most legal AI startups ignore. When paired with a solid law firm marketing strategy, the intake automation alone can dramatically improve your conversion rates.
Best for: Small to mid-size firms that want to automate intake and client follow-up.
How to Think About Legal AI Startups in Relation to Your Firm
This list covers a wide range of tools, from enterprise research platforms to intake automation. The right fit depends on a few things:
Your practice area matters.
A personal injury firm has very different AI needs than a corporate transactional practice. EvenUp and Eve are built for plaintiff work. Spellbook and Ironclad are built for contracts. Harvey and Legora are more general-purpose.
Your firm size matters.
Solo practitioners and small firms are not going to spend $1,000 per seat per month on Harvey. Clio, Lawmatics, and more affordable options make more sense at that scale.
Your biggest bottleneck matters.
If you have plenty of work but your team is drowning in documentation, a tool like EvenUp or Filevine can help. If your problem is not enough cases coming in the door, you need to fix your marketing before you invest in case management AI.
That last point is where most firms get it wrong. They invest in tools to work faster on cases they already have, but they never fix the pipeline. Your SEO, your PPC strategy, your content marketing, and your intake process are the foundation. Everything else is built on top of that.
Parting Thoughts About The Best Legal AI Startups
Legal AI startups are not slowing down. The money flowing into this space is staggering, and the tools are getting better every quarter. But technology alone does not build a successful law firm. You need clients first.
