Grouper, operated by Element3 Health, Inc. (d/b/a Grouper) and headquartered in Boston, Massachusetts, is a healthy-aging benefit company that connects older adults to social clubs, group activities, and virtual community programming through health plans. Its consumer product, "Hello by Grouper," is a membership platform offering live and on-demand instructor-led virtual classes, research-based monthly brain-health challenges, and members-only online events, with the goal of keeping members active, socially connected, and healthier as they age. Grouper distributes primarily through Medicare Advantage and other health-plan partners rather than a direct developer channel; it publishes no public developer portal, API, or SDK surface as of this profile, which was added to the API Evangelist network as a venture (a16z-associated) portfolio lead.
