Typical personal injury or mass tort cases epitomize classic underdog scenarios, where injured consumers face off against insurance giants or corporate titans. At the crux of these cases lies the challenge of collecting and analyzing complex medical and legal data, which is highly manual and costly for law firms. It can also cause significant delays in the litigation process—ranging from days to months or even years—leaving vulnerable plaintiffs uncompensated.

Enter Supio, an AI-powered software platform that is leveling the playing field for legal firms in personal injury and mass tort, empowering attorneys to achieve better outcomes for plaintiffs. Supio’s LLM-centric software automates the analysis of unstructured medical data and converts the synthesized data into an interactive platform with an AI-powered chat, which legal teams can leverage throughout the entire litigation lifecycle. Supio stands out as an AI-first company, addressing a massive industry challenge and enabling attorneys to focus on what they do best—taking on cases and securing justice for clients. We could not be more thrilled to partner with co-founders Jerry Zhou and Kyle Lam, as well as the entire Supio team, to lead their $25M Series A.

Personal Injury and Mass Tort: A Painful Need for Actionable Data and Workflow Automation

One major bottleneck in a typical personal injury or mass tort case is that attorneys and paralegals must painstakingly comb through hundreds or even thousands of pages of medical records, police reports and other case documents. Relevant details are often buried within this voluminous data, making them difficult to find. Moreover, even when this messy data is finally organized, whether through time-consuming internal efforts or by expensive outsourcing, the output is usually just a static document, like a PDF or Word file, which remains cumbersome for attorneys to analyze efficiently and extract critical insights needed to win the case.

This entire process of manual data collection, extraction and analysis is ripe for disruption. It presents a strong use case for AI to streamline the entire workflow end-to-end, which is why we’re so excited by Supio’s platform.

Supio: An AI-Centric Software Platform, Empowering Legal Professionals with “Superpowers”

Supio is tackling the aforementioned challenges for personal injury and mass tort head-on, mitigating the need for legal professionals, or expensive outsourced service providers, to summarize vast amounts of medical records. Supio’s LLM centric-software synthesizes relevant case data, creates the medical chronology and generates key legal documents (e.g., demand letters). Supio also converts the output into an interactive software platform with an AI-powered chatbot that functions akin to a legal co-pilot, enabling attorneys to surface case insights within seconds and prepare for key events (e.g., mediation, trial) across the end-to-end lifecycle of a case. Because Supio offers direct links to any insights gathered, lawyers trust the reliability of the software.

At Sapphire Ventures, our team has dedicated a great deal of time to the legal tech space over the last four years, with a particular focus on AI applications. We believe what sets the Supio platform apart is its genuine AI-first approach. Since day one, Jerry and Kyle have been unwavering in integrating AI into every aspect of the platform—from annotation and region-specific data extraction models to demand letter drafting and interactive AI-powered chat, which is a testament to the true AI-native expertise of the team. We are equally excited about the team’s vision to scale Supio’s core AI engine into other legal sectors, such as workers’ comp, medical malpractice, insurance defense and family law.

Backing a Visionary Team with a Differentiated Approach

From our very first meeting with Jerry, Kyle and the rest of the Supio team, their unique approach was immediately apparent—and refreshingly positive. Jerry articulates a clear, compelling vision for Supio, emphasizing the LLM-centric approach as the company’s core “superpower” and affirming their trajectory toward pioneering the next generation of Legal AI. And like any great team, the team chemistry is palpable. The long-standing relationship between Jerry and Kyle, who have known each other since childhood and collaborated at Microsoft, Avalara, and in previous entrepreneurial ventures, enhances their synergy. This connection extends to the broader team, fostering a cohesive culture focused on creating a Company of Consequence within the legal software industry. 

Supio exemplifies our conviction that Vertical AI is the new horizontal—a thesis that continues to guide many of our investments. We continue to look for AI-first businesses that are disrupting legacy industries with innovative technology and business models.
