Key Takeaways:

  • Supio raises $25M in Series A funding to enhance its AI platform for personal injury law.
  • Co-founded by former Microsoft engineers Jerry Zhou and Kyle Lam.
  • Uses generative AI to automate data-heavy legal processes, improving efficiency.
  • Multi-model AI approach ensures high accuracy and reliability in legal document processing.
  • Currently used by 30 law firms, with plans to expand to 100 by year-end.
  • Positioned for significant growth in the expanding legal tech market.

Supio, a Seattle-based AI platform co-founded by former Microsoft engineers Jerry Zhou and Kyle Lam, has secured $25 million in a Series A funding round led by Sapphire Ventures.

This brings Supio’s total funding to $33 million. The startup, founded in 2021, is gaining attention in the legal tech sector by using generative AI to streamline personal injury and mass tort law practices.

The idea for Supio stemmed from Zhou and Lam’s experiences handling large data sets at Microsoft and Avalara. They identified inefficiencies in managing data-heavy legal cases, particularly in personal injury law, and developed a platform to automate and optimize these processes.

“After attending numerous conferences and meeting with hundreds of lawyers across the U.S., Lam and I decided to focus on personal injury and mass tort plaintiff law,” said Zhou, CEO Supio. “These are practice areas that require compiling thousands of documents from multiple sources, and analyzing and finding information from the data within them.”

Supio’s AI platform assists legal professionals by quickly organizing, identifying, and summarizing crucial information from extensive documents like medical records and insurance claims. This significantly reduces the time needed to build strong cases.

One of Supio’s key features is its ability to run multiple AI models simultaneously, each trained to process and classify documents in specific ways.

This multi-model approach ensures high accuracy, with Zhou stating that their AI performs at “better than human levels of accuracy” without the errors seen in other AI tools. The legal industry’s cautious approach to AI adoption stems from concerns about data security and accuracy.

“Supio is providing flexible software featuring AI that can organize unstructured data and produce reliable results because we know timing and accuracy are critical,” Zhou stated.

In the end of 2023 the State Bar of California issued guidance advising legal professionals against entering clients’ information into AI tools that do not have “reasonable or adequate security.”

Supio addresses these issues by adhering to stringent security protocols, including compliance with privacy regulations like HIPAA and GDPR, and storing client data in its country of origin. The platform is designed to minimize errors, providing reliable and trustworthy results.

Currently, around 30 personal injury and mass tort law firms use Supio, with plans to increase to 100 firms by the end of the year. The company’s revenue model, based on subscription fees tied to case volume, has already led to over $1 million in annual recurring revenue.

“Law is extremely complex and nuanced, and most creators of work productivity tools lack a true understanding of the legal documents lawyers ultimately have to produce, which inhibits the development of accurate [AI] models,” Zhou added. “Supio has hundreds of models running at a given time with different functions to try to understand and classify documents. We then measure this against the work products that are expected and improve these results gradually.”

With the legal tech market expected to double in value by 2027, Supio is poised to expand its capabilities beyond personal injury and mass tort law, making it a significant player in the legal technology landscape.

Zhou and Lam, who have been friends since childhood, have frequently crossed paths in their careers. They both worked at Microsoft in the Office 365 division and later collaborated again at the tax compliance software company Avalara.

Supio’s success reflects the growing integration of artificial intelligence in the legal industry, setting new standards for efficiency, accuracy, and security in legal processes.
