Twilio is a cloud communication platform that provides APIs for sending SMS, voice calls, and other communication services. GroupGel uses Twilio to send group SMS and voice notifications to its users, making it easier for friends to communicate with each other. The company was founded by Colin MacLean and others who were frustrated with the time spent managing groups, so they created a platform that helps manage group communications more efficiently. GroupGel is currently at an early stage, with over 100 groups signed up and over 1,000 members, and is in negotiation to integrate its platform with large schools, churches, entrepreneurial organizations, and fitness clubs.
