Kraftful raises $1M to help smart home companies make better apps

If a thousand companies make their own smart light bulb, do a thousand companies also have to design a light switch app to control them? Kraftful, a company out of Y Combinator’s Summer 2019 class, doesn’t think so. Kraftful builds the myriad components that an IoT/smart home company might need, puzzle piecing them together into apps for each company without requiring them to reinvent the light switch (or the padlock button, or the smart thermostat dial) for the nth time.
