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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Bold the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Bold scores 17.8/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Bold
Each block below is one kind of artifact we hold for Bold. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
