Supio Recognized Among Top AI Legal Operating Systems as G2 Introduces New Category for Next Generation of Legal AI

The new category marks the next stage of legal AI: platforms built to connect a firm's systems, data, and people, not just speed up individual tasks

SEATTLE, Sept. 17, 2026 /PRNewswire/ -- Supio, the leading AI platform for plaintiff law, today announced that G2, the world's largest and most trusted software marketplace, has ranked Supio among the top three offerings in a new AI Legal Operating Systems category. The category recognizes an emerging class of agentic platforms built to coordinate and execute legal work across matters, data, applications and stakeholders, while keeping attorneys in control of every outcome

A New Category to Recognize a Maturing Market

G2 created the AI Legal Operating Systems category to distinguish AI platforms capable of moving beyond individual legal tasks to coordinate and execute multi-step legal work while maintaining the legal context, controls and human oversight required for professional use. According to G2, the category represents the next stage of legal AI: a firm-wide execution layer that connects systems of record, data, institutional knowledge and people to advance work across the legal environment.

Supio's inclusion reflects the company's rapid evolution from an early-stage legal AI company into an industry-defining platform for plaintiff law. In addition to being recognized as a top provider in this category, Supio was also named as a leader in G2's AI Legal Assistant category. Since emerging from stealth less than two years ago, Supio has achieved 17X ARR growth, raised $91 million from investors including Sapphire Ventures, Mayfield and Thomson Reuters Ventures, expanded headcount by more than 150%, and more than doubled its customer base in the first half of 2026.

Delivering Innovation and Leading Industry Transformation

Supio's growth has been driven by the expansion of its platform beyond individual AI-assisted tasks. In May, Supio launched Supio Agent, the industry's first end-to-end agentic AI platform purpose-built for plaintiff law, which plans, executes and delivers finished work with attorney oversight across the case, portfolio and firm levels. Just two weeks ago, at CAALA, Supio announced the development of long-horizon agents and vetted medical provider network integrations, extending Supio Agent from single-task assistance to autonomous execution across an entire case lifecycle. Along the way, Supio has forged key partnerships and integrations, including an industry-first direct integration with Thomson Reuters Westlaw Advantage, part of CoCounsel Legal, as well as medical document retrieval provider YoCierge and case management platform Litify.

"AI is most powerful when it is purpose-built to solve the real-world challenges of a specific industry," said Jerry Zhou, CEO and Co-Founder of Supio. "We're focused on innovating AI solutions that don't simply make individual tasks faster, but fundamentally improve how legal work gets done. G2's creation of the AI Legal Operating Systems category is meaningful validation of the market that is emerging around verticalized AI and the real impact these platforms can have. We're honored to be recognized as we continue to help define this next generation of legal technology, and are especially grateful to our customers for their continued partnership and trust."

Real-World Impact, Told by Supio Customers

Supio's recognition comes as its customer base continues to grow, with attorneys and legal teams increasingly relying on the platform to improve efficiency, accuracy, and decision-making across their practices. As of this announcement, 91% of reviewers gave Supio five stars, with one reviewer calling Supio an "indispensable tool for efficient legal practice."

G2 reviewers highlight the breadth of Supio and its ability to improve how legal teams work:

"Supio gives our attorneys insight into all cases in our current and past cases to be able to leverage that data to make better decisions."– William Davis, Chief Legal Officer and Partner at Daniel Stark, LLP

"As a paralegal, I'm constantly juggling a million things, and having a tool that can quickly pull information together and help me get a head start on a case is huge. I also really like that it was built with the actual workflow of a personal injury practice in mind. It doesn't feel like a generic AI tool that I have to figure out how to make useful, it actually fits into the work I'm already doing." – Marcell Ewing, GLP Personal Injury Attorneys

"We love how effective Supio has been for our firm. It helps us maximize efficiency while still maintaining a high level of care and attention for each case. With Supio, we can take on more cases, increase the value of each one, and make it easier for our staff to do their jobs at the highest level." – Jordan Travis, Partner at Rampart Injury Lawyers, LLC

This feedback reflects the broader shift G2 identified in creating the new category: legal AI is moving beyond tools that assist with isolated tasks toward platforms that can connect information, systems and workflows to actively advance legal work.

Supio's platform connects with the systems plaintiff firms already use, including case management, medical records, intake, communications, and legal research. Supio Agent builds medical chronologies, drafts demand letters, tracks liens and expenses, surfaces case law and generates firm-level analytics, while maintaining context across individual matters and the broader firm.
