Supio, a Seattle-based startup specializing in AI-driven legal data analysis, has successfully raised $60 million in a funding round led by Sapphire Ventures, with additional participation from Mayfield and Thomson Reuters Ventures. This latest investment brings the company’s total funding to $91 million, marking a significant milestone in its mission to transform legal workflows through artificial intelligence.
Transforming Legal Workflows with AI
Founded in 2021 by former Microsoft engineers Jerry Zhou and Kyle Lam, Supio aims to alleviate the burdensome manual processes that legal professionals face daily. The platform leverages advanced AI to automate the collection and analysis of complex, unstructured data, such as medical records, police reports, and expert opinions. By integrating with existing file systems, Supio provides attorneys and paralegals with a comprehensive understanding of case-related documents, significantly reducing the time and effort required for data review.
Every day, attorneys and paralegals spend thousands of hours manually reviewing medical records, police reports, and expert opinions, said Jerry Zhou, co-founder and CEO of Supio. Supio’s core product serves these users by giving them a deep understanding of their complex, unstructured data.
Addressing AI Accuracy in Legal Contexts
In the legal industry, the accuracy of AI applications is paramount. Supio addresses this concern by implementing human verification processes to mitigate potential AI-induced errors. The company focuses on specialized AI models and rigorous quality control at both the document and data levels, ensuring that the information provided is reliable and precise.
We focus deeply on specialized [AI] model and quality control at the document and data layer, Zhou explained. Our legal AI supports over 114 case types, and that number is growing in partnership with our customers.
Rapid Growth and Market Adoption
Supio has experienced remarkable growth over the past year. The company’s annual recurring revenue has quadrupled, and its customer base has expanded at a similar rate. Notable clients include Hughes & Coleman, Daniel Stark, Thomas Law Offices, and Whitley Law, among other personal injury and mass tort law firms.
To support this rapid expansion, Supio has recently appointed new heads of sales, customer success, and marketing and advertising. The company plans to use the new funding to further grow its team, aiming to double its current staff of 100 employees. Additionally, Supio intends to expand its Seattle headquarters and establish a new office to accommodate its increasing workforce.
The Broader Impact of AI in the Legal Industry
The legal industry is undergoing a significant transformation with the adoption of AI technologies. According to a survey, AI adoption in the legal profession nearly tripled from 11% in 2023 to 30% in 2024. Law firms are increasingly recognizing the competitive advantage that AI can provide, particularly in automating time-consuming tasks and enhancing data analysis capabilities.
AI has created a major inflection point for the legal industry as a whole, Zhou noted. Every firm across every sub-vertical of law is thinking about how they need to reinvent themselves for the AI era. If Excel transformed finance 30 years ago, AI will do the same for legal knowledge workers.
Future Prospects and Industry Implications
With the substantial new funding, Supio is well-positioned to continue its trajectory of rapid growth and innovation. The company’s focus on personal injury and mass tort law has already demonstrated significant value, and there is potential for expansion into other legal domains.
The success of Supio reflects a broader trend in the legal tech industry, where AI is increasingly being integrated to improve efficiency and accuracy. As law firms continue to adopt these technologies, the landscape of legal practice is poised for significant change, with AI playing a central role in shaping the future of the profession.
