Tin Can

Tin Can is a Seattle-based consumer hardware company behind a screen-free, landline-style Wi-Fi phone for kids — no apps, texting, or games, just voice calls with contacts that parents approve through a companion mobile app, with free unlimited calling between Tin Can devices. Backed by Greylock (which led a $12M round in 2025, bringing total funding to roughly $15.5M). Tin Can publishes no first-party developer API; its agent-facing surface is the Shopify-hosted storefront, which exposes a live MCP server, a UCP merchant profile, an llms.txt, and Shopify Customer Accounts OIDC on the tincan.kids domain.

Tin Can is profiled on the APIs.io network. Tagged areas include Company, Consumer, Hardware, Telecommunications, and Voice.

Tin Can’s developer surface includes support, engineering blog, pricing, authentication, and 10 more developer resources.
