Harvey, a generative artificial intelligence startup developing a platform for legal professionals, said today it has raised $160 million in new late-stage funding.

The Series F round was led by Andreessen Horowitz, featuring new investors WndrCo and accounts advised by T. Rowe Price Associates Inc., as well as returning investors in Sequoia, Kleiner Perkins, Conviction and Elad Gil.  The funding round values Harvey at $8 billion, up from $5 billion reported after its previous raise of $300 million in June and following a recent investment of €50 million, about $58 million, from EQT Growth.

Harvey, officially Counsel AI Corp., uses generative AI to deliver intelligent tools for legal professionals, including lawyers at law firms, in-house legal teams at corporations and professional services firms. Its tools are used for tasks such as contract analysis, due diligence, compliance and litigation support to improve efficiency.

More than 700 leading law firms and enterprises reportedly use the platform, representing over 74,000 attorneys. Customers include law firms such as Allen & Overy and the large accounting firm PricewaterhouseCoopers LLP.

Harvey uses a number of AI models, including a custom-trained model built in partnership with OpenAI Group PBC for case law. It allows the company to provide extensive domain knowledge and capabilities for complex workflows that require more than a single large language model call. Harvey has also partnered with PwC to co-build a tax AI assistant that combines curated tax datasets with Harvey’s LLM knowledge.

“If you just do retrieval, you can answer very simple questions about areas of law that you aren’t really an expert in, but that’s actually not that useful for most attorneys,” explained Winston Weinberg, co-founder and chief executive of Harvey. “With case law research, you’re finding ammo for your argument, and that’s much more difficult to do.”

In addition to the funding round, Harvey also announced the launch of Shared Spaces, a secure AI-driven collaborative platform for attorneys.

With Spaces, law firms can share customized AI tools, such as workflows and playbooks, without revealing proprietary prompts or essential information used to build them. Ideally, this will allow teams to complete contract work and deal cycles faster.

Harvey said it allows deeper and simpler collaboration between corporate in-house counsel to easily work with a law firm, providing greater transparency for AI use. It centralizes documents, complex analysis and workflows by allowing them to happen side-by-side.

“We all know that legal work is deeply collaborative — it’s about partnership,” said Rick Liu, strategic business development lead at Harvey. “And that partnership deserves a way to work that builds on that collaboration, instead of getting lost in email chains and version control.”

Shared Spaces provides direct access to Harvey’s existing powerful models, workflow builders, AI agents and more. Non-Harvey users can also be brought into access Spaces, in combination with provisioned roles and permissions, clients can control exactly who can access, view and edit artifacts and outputs. All of this is fully auditable, allowing a management team to monitor and control who can access, edit and generate documents and artifacts.
