Boldr

Boldr is a Techstars-backed consumer hardware company building energy-saving smart home climate control devices. Its two products are Kelvin, a smart infrared heater, and Klima, a smart thermostat controller for mini-split air conditioners that also monitors appliance health so units last longer with fewer issues. Both devices are managed through the Boldr mobile app, which lets homeowners control climate settings remotely and track energy usage to lower utility bills. Boldr also runs Boldr Pro, a program for HVAC contractors. The company sells direct to consumers through a Shopify-hosted online store at shopboldr.com and does not currently publish a first-party developer API; its only public machine-readable surface is the Shopify Customer Account OIDC discovery served at the storefront host.

Boldr is profiled on the APIs.io network. Tagged areas include Company, Smart Home, Energy, Climate Control, and IoT.

Boldr’s developer surface includes engineering blog, support, and 5 more developer resources.
