Bold

Bold (Age Bold, Inc.) is an AI-enabled healthy-aging company founded in 2019 by Amanda Rees and Hari Arul that combines age-friendly virtual care with senior-focused exercise and nutrition programs for Medicare members. The platform delivers personalized at-home programs — live and on-demand classes, balance and fall-prevention regimens, pain and mobility programs, nutrition coaching, and telehealth visits with clinicians — to adults 65 and older, distributed through Medicare Advantage plans, provider groups, and the CMS ACCESS program rather than sold as a developer platform. Bold reports its balance programs lower fall risk and its pain programs reduce joint pain among participating members, and states its platform is HIPAA compliant and requires no lengthy IT integration for plan partners. The company has raised roughly $27M, with a $17M Series A led by Rethink Impact alongside Andreessen Horowitz Bio + Health, Khosla Ventures, Samsung Next, GingerBread Capital, and Primetime Partners. As of this enrichment pass Bold publishes no public developer portal, API documentation, OpenAPI definition, SDKs, or partner API surface — integrations are handled through its partnerships team.

Bold is profiled on the APIs.io network. Tagged areas include Company, Digital Health, Healthy Aging, Medicare, and Telehealth.

Bold’s developer surface includes signup flow, support, engineering blog, and 13 more developer resources.
