Chapter

Memoir, Inc. , trading under the name Chapter is a US-based company dedicated to guiding older Americans through the complexities of Medicare, providing personalized advisory services and efficient tools for healthcare navigation. Founded in 2020 and headquartered in New York, US, Chapter Medicare specializes in Medicare advisory services. The company was established by Ari Parker, Cobi B, and Corey Metzman, with Cobi B serving as CEO.

In April 2026, Chapter Medicare raised USD 100 million in series E funding led by Generation Investment Management, with participation from Fifth Down Capital, 8VC, Stripes, XYZ Ventures, Addition, Narya, Susa Ventures, and Maverick Capital. The series E funding values Chapter Medicare at USD 3 billion post-money. Chapter Medicare offers a comprehensive suite of advisory services to assist older Americans in navigating Medicare complexities. Its core service includes personalized guidance from licensed Medicare Advisors who help clients understand their enrollment options.

The company also operates the Chapter OTC App, facilitating efficient redemption of Over the Counter credits, and evaluates various insurance plans to identify optimal coverage for costs not addressed by Original Medicare, primarily targeting individuals aged 65 and older across the US. Chapter Medicare generates revenue by providing advisory services to clients seeking Medicare-related guidance. Revenue is primarily derived from commissions on insurance plans that clients enroll in, facilitated by partnerships with over 50 organizations. The business operates on a fee-for-service model, compensating advisors based on successful enrollments in recommended plans.

The company plans to use the April 2026 funding to accelerate growth and launch additional financial products.
