Candid answers by the company
Connecting people and enabling conversations was always the core idea. In 2011, Augustus Franklin created a chat tool that allowed visitors to a webpage to communicate with each other. This concept evolved initially into an engagement tool for online marketplaces and eventually into the foundation of what it is today – a comprehensive campaigning platform, one that empowers changemakers, organizations, and businesses to reach millions of constituents and facilitates change, one message, one call, one campaign at a time!
