Angle Health has secured $134 million in an oversubscribed Series B round as the San Francisco-based company accelerates the scale of its AI-powered health benefits platform designed for small and mid-sized businesses. Portage led the financing with participation from Blumberg Capital, Mighty Capital, PruVen Capital, SixThirty Ventures, TSVC, Wing VC, and Y Combinator. The round included a mix of equity and debt, bringing the company’s total funding to nearly $200 million.
The company, founded by former Palantir engineers Ty Wang and Anirban Gangopadhyay, has expanded significantly since its 2022 funding round. Revenue has increased 26 times during that period, while Angle Health has grown to serve more than 3,000 employers across 44 states. The company reports an over 80 percent renewal rate, a 36 percent reduction in median rate increases compared to the broader small business market, and a 90 percent member-level customer satisfaction score through the first three quarters of 2025.
Angle Health’s growth comes as employer healthcare expenses are projected to increase by the most in 15 years, according to research from Mercer. The company’s platform uses proprietary AI models trained on millions of de-identified patient records to identify risk patterns and help employers and brokers structure plans that deliver more predictable costs and better outcomes. The system incorporates medical and pharmacy data, demographic information, real-time claims patterns, and broader population health metrics to forecast needs and deploy personalized interventions.
The company’s Benefit Builder product enables brokers to generate firm-underwritten quotes for custom plans in minutes rather than weeks. Brokers using the system have reported stronger close rates and improved client satisfaction due to faster quoting, competitive pricing, and enhanced visibility through the company’s Health Scorecard.
Portage, which manages more than $4 billion and spans fintech and financial services, said Angle Health represents a new model for modernizing the healthcare benefits ecosystem. The investor highlighted the company’s focus on rebuilding the operational and financial infrastructure behind employer-sponsored coverage.
Angle Health continues to position its vertically integrated model as a solution for small and mid-sized businesses as they navigate rising healthcare costs and seek greater transparency, more efficient administration, and tailored employee support.
KEY QUOTES:
“We’re rebuilding healthcare infrastructure and care pathways to give all employers access to the comprehensive benefits historically reserved for large enterprises.”
“The healthcare benefits ecosystem wasn’t designed for the small-to-medium-sized businesses that employ nearly half of America’s workforce, and legacy technology can’t deliver on the efficiencies and savings unlocked by AI. We’re rebuilding healthcare infrastructure and care pathways to give all employers access to the comprehensive benefits historically reserved for large enterprises.”
Ty Wang, Co-Founder and CEO, Angle Health
