Harvey is the platform built to meet the standards of the world’s leading professional service firms.
Harvey has closed a $550 million funding round at a $15.6 billion valuation and acquired AI agent security startup Guardrails AI. The round was co-led by Lightspeed Venture Partners and Diffusion, with participation from Sapphire Ventures and Whale Rock Capital Management. The legal AI company has raised more than $1.5 billion total, making it the most valuable and best-funded firm in its sector. Annual recurring revenue has surpassed $400 million, whilst the customer base has grown to over 3,000 organisations, up from 1,300 in March. Harvey recently released Tenet, its first fine-tuned legal model, built on Moonshot AI's Kimi K3. The company routes tasks to the cheapest capable model rather than using one model for every request. This is Harvey's fourth acquisition this year, with terms undisclosed.
Legal tech startup Harvey has reached a $15.6 billion valuation after raising $550 million in its latest funding round. The company plans to use the capital to develop its own AI models. Harvey provides AI-powered tools for legal professionals. The substantial funding reflects growing investor confidence in specialised AI applications for professional services. The new valuation marks significant growth for the startup, which operates in the legal technology sector. The company is focusing its resources on building proprietary artificial intelligence technology rather than relying solely on third-party models.
Macpherson Kelley rolls out :Harvey: firmwide. by Harvey Team - Sep 2, 2026 Macpherson Kelley, a leading Australian commercial law firm with a 121-year history, is deploying Harvey firmwide across its lawyers and all eight practice groups. The firmwide rollout follows a year-long pilot and comprehensive evaluation of legal AI platforms. Macpherson Kelley selected Harvey for the strength of the platform and its approach to implementation and adoption, with Harvey's teams working closely alongside the firm's lawyers and leadership throughout the evaluation. During the pilot, Harvey's Customer Success and Legal Engineering teams worked onsite with Macpherson Kelley across Australia to identify high-impact use cases and develop workflows tailored to its practices. With the firmwide rollout, the teams will build on that foundation, expanding how Harvey supports the firm's lawyers across litigation, drafting, review, and other complex legal work while helping them deliver greater value for clients. "We spent a year evaluating Harvey with our lawyers and testing it against the alternatives before making the decision to go firmwide," said Grant Guenther, National Managing Principal at Macpherson Kelley. "What stood out was not only the strength of the platform, but the partnership behind it. Rolling out Harvey across the firm is an investment in our people and in how we continue to strengthen the service we deliver to our clients." "Macpherson Kelley approached this decision with tremendous thoughtfulness, taking the time to understand where Harvey could have the greatest impact across its practice," Ashleigh Whittaker, Australian Country Manager. "We're proud to support the firm as it brings Harvey to every lawyer and look forward to building on the strong relationship our teams have developed."
Introducing Horizon Scanning. Horizon Scanning helps legal teams monitor, assess, and take action on the changes that matter most. by Harvey Team - Sep 1, 2026 The pace of regulatory change isn't slowing down: 63% of legal departments say their monitoring and compliance workloads increased in 2026. Many existing monitoring tools don't even save teams time because alerts arrive through fragmented feeds, without prioritization, and siloed from where next steps need to happen. Changes can slip through, and it can be costly to miss a key update. Harvey is introducing Horizon Scanning in Harvey to help legal teams turn monitoring into actionable next steps. Teams can customize alerts, receive notifications for key regulatory and legislative updates, and immediately take action on the most impactful developments in one connected platform. Built with a cohort of design partners across law firms and in-house teams, Horizon Scanning helps legal teams quickly act on the changes that matter most. Create tailored scans relevant to you. Most monitoring tools draw from a fixed repository, which means coverage may be rigid or irrelevant to what your business prioritizes. With Horizon Scanning in Harvey, teams can simply describe what they need to track in plain language - a topic, a region, a named regulator. Harvey will automatically build a scan, drawing on more than 12,000 sources across 100+ jurisdictions alongside public sources the user describes. For example, an in-house team can shape the scope of a scan to data protection developments in the jurisdictions where the company actually holds data, or create a separate scan for each subsidiary. Quickly identify which changes matter most. Every scan feeds a single dashboard that shows what moved, with the most consequential developments surfaced first. Determining what changed is just the first step - the critical work is understanding who it affects, what they need to do, and by when. Each update arrives with a relevance assessment, so that it is easy to gauge urgency before digging into the details. Teams can also receive email digests of daily changes, helping them access insights directly in their inbox. Let's say there's a new anti-money laundering rule that impacts a financial services legal team. They can find out about the change the same day it's published via an email alert. Then, Harvey can help them quickly determine which entities are impacted, what has to change operationally, and how long they have to prepare. Move from update to next step. Since Horizon Scanning is part of Harvey's agentic platform, alerts connect to downstream work in one single system. Ask a question about a development in plain language and get an answer grounded in the source. Teams can turn scans into a memo revision, a recommended policy update, or an interactive timeline of upcoming obligations without leaving the dashboard. For a firm's privacy practice, that can mean tracking data protection regulators across member states, updating guidance by directly pulling the right documents from their DMS into queries, and drafting a client alert the same day new guidance lands. For an in-house compliance team, it can mean Harvey directly flagging which internal policies are affected by a tariff change and suggesting revisions, helping them draft new guidelines and flag any operational concerns faster. Scans can be shared across a team, so practice groups and business stakeholders work from the same view. Harvey is building Horizon Scanning as a foundation for proactive legal work in Harvey, where monitoring, analysis, and the work that follows all live in one place. Horizon Scanning is currently available in Early Access for Harvey customers, with general availability to follow. If you're interested in learning more about Harvey, get in touch with its team.
