Supio Raises 60 Million to Revolutionize Legal Data Automation with AI

Supio, an innovative startup leveraging artificial intelligence to automate data collection and analysis for legal teams, has successfully raised $60 million in a recent funding round. Led by Sapphire Ventures with contributions from Mayfield and Thomson Reuters Ventures, this investment brings Supio’s total capital raised to $91 million. The company plans to allocate these funds toward accelerating growth, expanding its workforce, and enhancing go-to-market strategies.

Headquartered in Seattle, Supio intends to expand its main office and establish a new location while nearly doubling its current staff of 100 employees. This growth reflects the company’s strong position in the competitive AI legaltech market, where law firms are increasingly adopting AI solutions to stay competitive and improve efficiency.

Supio’s AI-powered platform focuses on personal injury law, connecting seamlessly with law firms’ existing file systems to assist with case management. The platform automates the review of complex, unstructured documents such as medical records, police reports, and expert opinions—tasks that traditionally consume thousands of hours of manual labor by attorneys and paralegals.

To ensure accuracy and mitigate AI errors, Supio incorporates human verification into its workflows. The company emphasizes specialized AI models and rigorous quality control at the document and data layers, supporting over 114 case types with ongoing expansion in collaboration with customers.

Supio has experienced remarkable growth, with annual recurring revenue and customer base both increasing fourfold. Its clientele includes prominent personal injury and mass tort law firms such as Huges & Coleman, Daniel Stark, Thomas Law Offices, and Whitley Law. To support this expansion, Supio has recently appointed new leaders in sales, customer success, and marketing.

Co-founder and CEO Jerry Zhou highlights that AI is driving a major transformation within the legal industry, likening its impact to how Excel revolutionized finance decades ago. As AI adoption in legal professions nearly tripled from 11% in 2023 to 30% in 2024, firms across all legal sub-verticals are rethinking their workflows to remain competitive in the AI era.

Supio’s origin traces back to Zhou and his childhood friend and co-worker Lam, who identified an opportunity to transform document workflows while working at Avalara, a tax compliance software firm. Their vision to automate and enhance the understanding of complex legal documents has positioned Supio as a key player in the evolving legaltech landscape.

As the legal industry faces increasing pressure to adopt AI solutions, startups like Supio are leading the charge by delivering practical, AI-powered tools that enhance productivity, reduce manual workloads, and improve case outcomes. Supio’s success underscores the broader trend of AI integration transforming legal workflows and knowledge work.
