Buzzeromatic is a Seattle-based startup that simplifies apartment resident management by integrating Twilio's API with a web interface or SMS commands, allowing users to admit guests, create passwords, receive voice messages from delivery staff, and more. The company's co-founder, Andres Krogh, credits Twilio's ease of use and cost-effectiveness for enabling the creation of Buzzeromatic. Krogh shares his experience developing with Twilio, highlighting the API's simplicity and flexibility in handling state management and other complex tasks. He also expresses enthusiasm for using Twilio to build humanitarian projects, such as a "Just called to say I love you" site, in the future.
