Supio, the artificial intelligence-driven legal analytics startup, has secured $60 million in a new funding round led by Sapphire Ventures, with additional participation from Mayfield and Thomson Reuters Ventures.
The fresh capital injection increases Supio’s total fundraising to $91 million. CEO and co-founder Jerry Zhou said the funds will accelerate the company’s expansion initiatives, bolster hiring efforts, and enhance marketing strategies. Supio intends to expand its headquarters in Seattle and is also planning to open an additional office location, aiming to nearly double its current team of roughly 100 employees.
Supio offers a specialized AI platform primarily targeting the personal injury legal sector. The system seamlessly integrates into firms’ existing document management workflows, automating the often labor-intensive review of medical files, police reports, expert testimonies, and other complex unstructured data types. According to Zhou, Supio’s technology employs “human verification” steps to significantly reduce AI-related inaccuracies and confirm reliable outputs.
“Every day attorneys and paralegals spend thousands of hours manually reviewing various documents,” Zhou stated. “Our system empowers them to quickly, accurately, and thoroughly grasp the nuances of complex, dynamic data.”
The startup was founded by Zhou and his childhood friend Lam—both former employees at tax compliance software company Avalara. They departed together to address a gap they saw in document-intensive legal operations, aiming to meaningfully streamline and enhance workflows.
With adoption rapidly accelerating across law firms, AI technology has become a critical differentiator in the highly competitive legal landscape. Industry surveys indicate significant year-over-year growth in AI usage, climbing from approximately 11% in 2023 up to nearly 30% in 2024.
Supio’s platform now supports over 114 distinct case types, and the company plans to expand that capability further through close collaboration with customers. Its rapidly growing client roster includes leading personal injury firms such as Hughes & Coleman, Daniel Stark, Thomas Law Offices, and Whitley Law.
Reflecting robust growth, Zhou noted that Supio’s annual recurring revenue has quadrupled over the past year, matched by a corresponding fourfold increase in its customer base. To manage this rapid scale-up effectively, Supio has recently appointed senior leaders to head up sales, customer success, and marketing.
Zhou believes that AI technology represents a transformative force for professions historically driven by extensive manual data analysis. “We’re at a pivotal moment for the legal industry. As Excel fundamentally reshaped finance decades ago, we believe AI-powered platforms like Supio will similarly redefine the future of legal work.”
