Playbrush

Playbrush is a consumer oral-care technology brand that makes smart, gamified electric and sonic toothbrushes for children (ages 3+), pairing a Bluetooth-connected brush with a companion mobile app that turns brushing into interactive games and coaching to build good dental-hygiene habits. Founded as a UK/Austria startup and backed by Speedinvest, the Playbrush product line has since been acquired by SUNSTAR and is now sold under the GUM Playbrush brand; the former playbrush.com domain 302-redirects to a Sunstar GUM product page. Playbrush is a hardware/consumer-app company and exposes no public developer portal, API, specification, or /.well-known/ discovery surface. This profile was surfaced as a Speedinvest portfolio company and added to the API Evangelist network as a lead; enrichment confirmed there is no API surface.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

Playbrush is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.

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 — Playbrush scores 5.7/100 (minimal), 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.

The organization behind the API

Playbrush is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
