Indigo, a vertically integrated, AI-driven medical professional liability platform, has secured $50m in fresh capital through an oversubscribed Series B funding round, as it looks to scale its technology across the US.
The $50m raise was led by existing investor Rubicon Founders, with significant participation from new backer Town Hall Ventures. Other existing strategic investors, including Optum Ventures, also contributed to the round, underscoring continued confidence in Indigo’s growth trajectory and product strategy.
Founded in 2023, Indigo offers medical professional liability insurance to physicians spanning a broad range of specialties.
The company has positioned itself as a vertically integrated insurer, combining underwriting, distribution and risk assessment within a single platform designed to replace manual and fragmented legacy processes.
Central to Indigo’s offering is its proprietary AI platform, Lux, which applies advanced machine learning and purpose-built risk models to automate underwriting workflows. These processes have historically relied on labour-intensive human review. By automating key decision points, Indigo aims to deliver faster, more consistent and more accurate coverage outcomes for physicians and brokers alike.
Since its launch, the company has grown quickly, insuring nearly 1,000 providers nationwide and surpassing $10m in premiums.
By the end of 2025, 20% of submissions were fully underwritten automatically, highlighting both the scalability of the Lux platform and the impact of domain-specific automation within insurance.
Indigo CEO Jared Kaplan said, “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.”
Rubicon Founders co-founder and partner Matt Kim said, “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.”
Town Hall Ventures co-founder and general partner David Whelan said, “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.”
