Supio Announces $60M Series B to Accelerate Adoption of Legal AI in Plaintiff Law

Supio, a legal AI platform trusted by personal injury and mass tort plaintiff law firms, today announced it has raised $60 million in Series B funding. The round was led by existing investor Sapphire Ventures, with participation from new investors Mayfield and Thomson Reuters Ventures. The new investment brings Supio’s total funding to date to $91 million.

The company’s unique approach to combining specialized AI with human expert verification has set a new standard for accuracy and reliability in legal AI, addressing the critical challenge of hallucinations that plague many automated solutions. This has been particularly valuable in litigation settings where precision and confidence in the data are paramount.

“Supio is transforming how personal injury and mass tort litigation is practiced through specialized AI,” said Rajeev Dham, Partner at Sapphire Ventures and Supio Board Member. “We believe their exponential growth demonstrates that law firms are embracing AI tools that deliver measurable advantages in case preparation and outcomes. We aim to recognize a category-defining company when we see one, and we’re proud to deepen our partnership with the team revolutionizing this practice area.”

The Series B funding will support the company’s ambitious growth plans, including expanding its engineering and AI research teams, accelerating product development and scaling go-to-market operations to reach more law firms nationwide. The company recently launched a new suite of document intelligence tools to meet the needs of current users as well as taking into account what AI capabilities work best for personal injury cases.

“This funding allows us to expand our AI platform that’s already helping law firms win better settlements and litigation for their clients,” said Jerry Zhou, co-founder and CEO of Supio. “Our combination of specialized legal AI and human verification provides attorneys with accurate insights and drafting they can confidently use in negotiations and court. We’re building technology that doesn’t just save time, but fundamentally improves case outcomes.”

Strengthens Leadership Team to Meet Growing Market Demand

Supio also announced the appointment of several key executives to support its rapid growth, including Jay Deubler to lead Sales, Gwen Sheridan to lead Customer Success and Jim Sinai to head Marketing. Jay Deubler joins with proven experience scaling revenue at Avalara from early stages through IPO. Gwen Sheridan brings valuable expertise from Highspot where she led all post-sales functions. Jim Sinai, a vertical SaaS marketing specialist, previously launched Einstein AI at Salesforce and led Procore through its IPO.

“Our growth since Series A confirms what we’ve believed all along—that specialized AI built for personal injury and mass tort law can transform how these practices operate,” Zhou said. “By expanding our executive team, we’re positioning Supio to meet the tremendous market demand for our AI-first approach to legal document workflows, and to deliver concrete results: faster case resolution, stronger settlements, and ultimately better outcomes for the individuals seeking justice.”

Accelerating Growth and Impact Since Series A

Since emerging from stealth in August 2024 with its $25 million Series A funding, Supio has experienced four times Annual Recurring Revenue (ARR) growth and demonstrated the transformative impact of its AI platform. The company has significantly expanded its customer base, now serving many of the top personal injury and mass tort law firms across the United States including Huges & Coleman, Daniel Stark, Thomas Law Offices, and Whitley Law.

Supio’s specialized AI platform has proven particularly valuable in helping firms win bigger. Firms such as Travis Legal Offices have reported getting at least 20-30% per case while Thomas Law reported increasing their annual case volume 62% since adopting Supio. In high-stakes litigation, Supio helped TorHoerman Law secure a landmark $495 million verdict against Abbott Labs. By combining AI-powered document analysis with rigorous human verification, Supio has established itself as the trusted solution for legal teams handling complex cases involving thousands of documents.

“Thomson Reuters Ventures invests in innovative companies that align with our strategic focus and the markets we serve. In the legal industry, personal injury and mass tort litigation demand specialized AI solutions designed specifically for these complex practice areas, and Supio addresses these unique challenges with both accuracy and depth,” said Tamara Steffens, Managing Director, Thomson Reuters Ventures. “We’re confident that Supio’s platform, built from the ground up, will become essential for firms serious about maximizing case outcomes.”

Burford Issues YPF Litigation Update Ahead of Pivotal Appeal Hearing

By John Freund |

Burford Capital has released a detailed investor update ahead of a key appellate hearing in its high-profile litigation against Argentina over the renationalization of YPF.

According to Burford’s press release, oral arguments in the consolidated appeal—referred to as the “Main Appeal”—are scheduled for October 29, 2025, before the US Court of Appeals for the Second Circuit. The hearing will address Argentina’s challenge to a $16 billion judgment issued in 2023, as well as cross-appeals concerning the dismissal of YPF as a defendant. The release outlines the appellate process and timelines in granular detail, noting that a ruling could come months—or even a year—after the hearing, with additional delays possible if rehearing or Supreme Court review is pursued.

Burford also clarified the distinction between the Main Appeal and a separate appeal involving a turnover order directing Argentina to deliver YPF shares to satisfy the judgment. That order has been stayed pending resolution, with briefing set to conclude by December 12, 2025. Meanwhile, discovery enforcement is proceeding in the District Court, where Argentina has been ordered to produce documents—including internal and “off-channel” communications—amid accusations of delay tactics.

International enforcement efforts continue in at least eight jurisdictions, including the UK, France, and Brazil, where Argentina is contesting recognition of the US judgment.

The update serves both as a procedural roadmap and a cautionary note: Burford stresses the unpredictable nature of sovereign litigation and acknowledges the possibility of substantial delays, setbacks, or settlements at reduced values.

The Alliance for Responsible Consumer Legal Funding Applauds Governor Newsom for Signing AB 931

The Alliance for Responsible Consumer Legal Funding Applauds Governor Newsom for Signing AB 931, the California Consumer Legal Funding Act

The Alliance for Responsible Consumer Legal Funding (ARC) expressed its deep appreciation to Governor Gavin Newsom for signing Assembly Bill 931 -- The California Consumer Legal Funding Act -- into law. Authored by Assemblymember Ash Kalra (D–San Jose, 25th District), this landmark legislation establishes thoughtful and comprehensive regulation of Consumer Legal Funding in California—ensuring consumer protection, transparency, and access to financial stability while legal claims move through the judicial process.

The law, which takes effect January 1, 2026, provides consumers with much-needed financial support during the often lengthy resolution of their legal claims, helping them cover essential living expenses such as rent, mortgage payments, and utilities.

“This legislation represents a major step forward for California consumers,” said Eric Schuller, President of the Alliance for Responsible Consumer Legal Funding. “AB 931 strikes the right balance between protecting consumers and preserving access to a financial product that helps individuals stay afloat while they await justice. Consumer Legal Funding truly is about funding lives, not litigation.”
Key Consumer Protections Under AB 931

The California Consumer Legal Funding Act includes robust safeguards that prohibit funding companies from engaging in improper practices and mandate full transparency for consumers.

The Act Prohibits Consumer Legal Funding Companies from:

• Offering or colluding to provide funding as an inducement for a consumer to terminate their attorney and hire another.
• Colluding with or assisting an attorney in bringing fabricated or bad-faith claims.
• Paying or offering referral fees, commissions, or other forms of compensation to attorneys or law firms for consumer referrals.
• Accepting referral fees or other compensation from attorneys or law firms.
• Exercising any control or influence over the conduct or resolution of a legal claim.
• Referring consumers to specific attorneys or law firms (except via a bar association referral service).

The Act Requires Consumer Legal Funding Companies to:

• Provide clear, written contracts stating:
• The amount of funds provided to the consumer.
• A full itemization of any one-time charges.
• The maximum total amount remaining, including all fees and charges.
• A clear explanation of how and when charges accrue.
• A payment schedule showing all amounts due every 180 days, ensuring consumers understand their maximum financial obligation from the outset.
• Offer consumers a five-business-day right to cancel without penalty.
• Maintain no role in deciding whether, when, or for how much a legal claim is settled.

With AB 931, California joins a growing list of states that have enacted clear and fair regulation recognizing Consumer Legal Funding as a non-recourse, consumer-centered financial service—distinct from litigation financing and designed to help individuals meet their household needs while pursuing justice.

“We commend Assemblymember Kalra for his leadership and Governor Newsom for signing this important legislation,” said Schuller. “This act ensures that Californians who need temporary financial relief during their legal journey can do so safely, transparently, and responsibly.”

About the Alliance for Responsible Consumer Legal Funding (ARC)

The Alliance for Responsible Consumer Legal Funding (ARC) is a national association representing companies that provide Consumer Legal Funding, non-recourse financial assistance that helps consumers meet essential expenses while awaiting the resolution of a legal claim. ARC advocates for fair regulation, transparency, and consumer choice across the United States.
