Chapter Raises US$100m to Simplify Medicare for Seniors

An AI-native retirement platform has secured significant investment as it works to transform how American seniors access and understand Medicare coverage, highlighting growing investor confidence in healthcare technology solutions that serve older demographics.

Chapter has raised US$100m in Series E funding, with Generation Investment Management leading the round. New investors Fifth Down Capital and 8VC joined the investment, alongside existing backers Stripes, XYZ Venture Capital, Addition, Narya Capital, Susa Ventures and Maverick Ventures.

The funding arrives during a period of growth for the platform, which has more than doubled its valuation. The company's approach centres on addressing longstanding challenges in Medicare navigation, where complexity and opacity have historically created barriers for retirees seeking appropriate healthcare coverage.

Chapter's business model prioritises AI to deliver personalised Medicare guidance at scale. The platform analyses thousands of plan variations to match beneficiaries with appropriate coverage options based on their specific healthcare needs and financial circumstances.

"Most technology companies ignore retirees. Our mission is to ensure every senior is able to preserve their health, wealth and purpose by building products that we wish our own parents had at the outset of retirement" says Cobi Blumenfeld-Gantz, CEO and co-founder of Chapter.

"We are the only company that reviews every single Medicare plan nationwide and offers unbiased guidance and we are building additional products that will empower seniors to author the next chapter of their lives."

Addressing Medicare complexity through technology

The Medicare system presents significant navigation challenges, with thousands of plan variations and constantly shifting costs creating confusion for beneficiaries.

Chapter's platform differentiates itself through comprehensive coverage analysis, reviewing every Medicare plan available nationwide. This enables licensed advisors to deliver personalised recommendations without the influence of commission structures that could affect traditional broker guidance.

The company's technology infrastructure processes vast amounts of healthcare data to identify optimal plan matches. This data-driven methodology aims to remove the guesswork from Medicare selection, helping beneficiaries understand which options best serve their specific medical and financial situations.

"Cobi and his team have earned the trust of American seniors by building a data and AI platform that provides accurate information and impartial advice in an industry largely devoid of either," says Anthony Woolf, partner at Generation Investment Management.

Financial performance demonstrates market demand

Chapter's 2025 financial results indicate market share acquisition in the Medicare advisory space.

Revenue increased threefold over the past year, with annual recurring revenue surpassing US$100m. The company achieved this growth while maintaining consistent corporate headcount levels, demonstrating the operational efficiency of its AI-driven business model.

The financial trajectory suggests strong demand for technology-enabled Medicare guidance services. Chapter's ability to scale revenue without proportional increases in staffing reflects the leverage inherent in its AI-powered platform.

Expanded healthcare management tools

Chapter has developed additional features beyond plan selection to address specific challenges facing retirees in healthcare management.

The platform now includes a provider directory and a prescription cost calculator, both integrated into the core system to help members control overall healthcare expenditure. These tools aim to provide transparency across multiple aspects of Medicare usage, from initial plan selection through ongoing care management.

The prescription cost calculator enables members to compare medication expenses across different Medicare Part D plans, helping beneficiaries identify coverage options that minimise out-of-pocket pharmaceutical costs. The provider directory helps ensure that preferred doctors and specialists accept specific Medicare plans before enrolment.

The investment could signal broader market recognition of the need for technology-enabled healthcare navigation services, particularly for older adults who may face difficulties with traditional Medicare enrolment processes.
