AI legaltech startup Supio has raised $60 million in new funding to grow its AI-powered legal analysis platform. The round was led by Sapphire Ventures, with backing from Mayfield and Thomson Reuters Ventures. This brings Supio’s total funding to $91 million.
The Seattle-based company plans to use the funds to grow fast. It will double its team of 100, expand its headquarters, and open a new office. Supio is also ramping up go-to-market efforts as part of this next growth phase.
Supio joins a wave of AI startups transforming the legal sector. Law firms are under pressure to adopt AI tools or risk being left behind. In fact, a recent survey found that AI adoption in legal firms jumped from 11% to 30% between 2023 and 2024.
The company was born from a simple idea. Co-founders Jerry Zhou and Lam, friends and former colleagues at Avalara, wanted to change how legal teams work with documents. They saw that lawyers and paralegals waste hours every day reviewing medical records, police reports, and expert files. Supio steps in by automating this process.
Its platform connects directly to a law firm’s existing file system. From there, it scans and analyzes complex, unstructured data—especially for personal injury cases. Supio adds a human layer to review AI-generated outputs. This helps reduce errors and builds trust in the results.
Zhou said the platform now supports more than 114 types of cases, and that number keeps growing. Supio is working closely with customers to refine and expand its tools.
The startup’s momentum is clear. Over the past year, it has quadrupled its recurring revenue and client base. Leading law firms like Hughes & Coleman, Daniel Stark, Whitley Law, and others are already using the platform to boost productivity.
To support this growth, Supio recently hired new leads for sales, customer success, marketing, and advertising. These hires reflect a broader plan to position Supio as a top legal AI player.
Zhou believes the legal industry is at a tipping point. “Thirty years ago, Excel changed finance. Today, AI will reshape legal work in the same way,” he said.
Supio’s success shows that law firms are ready to evolve. And AI is quickly becoming the tool to make that transformation real.
