Indigo raises $50 million

Indigo, a provider of medical professional liability, announced the closing of a $50 million “oversubscribed” Series B financing, led by existing investor Rubicon Founders, with significant participation from new investor Town Hall Ventures, and other existing strategic investors including Optum Ventures.

The new capital will support continued expansion of Indigo’s AI-powered underwriting and distribution platform, enabling faster, more precise coverage decisions for physicians and brokers nationwide.

Founded in 2023, Indigo provides medical professional liability insurance to physicians across a broad range of specialties through the Indigo Risk Retention Group. The company has grown to insure nearly 1,000 providers nationwide and has surpassed $10 million in premium. Indigo’s AI platform, Lux, applies “advanced machine learning and purpose-built risk” models to automate underwriting workflows traditionally handled through manual, labor-intensive processes.

“The next phase of innovation in insurance requires technology purpose-built for complex, specialty risk. This funding allows us to expand our technology footprint, deepen underwriting rigor, and deliver an exceptional ease-of-doing-business experience for brokers—while ensuring physicians receive pricing and coverage aligned with their true risk profile. Our results demonstrate that advanced automation can drive profitable growth while reducing operational friction.” – Jared Kaplan, CEO of Indigo.

“Indigo is executing at the intersection of deep domain expertise and AI excellence. Their vertical AI strategy isn’t incremental—it fundamentally redefines how risk is assessed, priced, and managed. We’ve seen firsthand how their models improve both the speed and quality of underwriting decisions, and this capital will help them scale faster than legacy carriers have been able to for decades.” – Matt Kim, Indigo Co-Founder and Partner at Rubicon Founders.

“Indigo represents exactly the type of category-defining opportunity we look for: By layering machine learning over deep insurance expertise, they’ve built a defensible moat and a superior underwriting product. Their ability to quote with lower administrative overhead creates a meaningful advantage in a legacy market, ultimately driving down premiums for high-quality medical groups.” – David Whelan, Co-Founder & General Partner at Town Hall Ventures.
