Relay, a peer-to-peer texting platform, was launched by Daniel Souweine after running a successful national volunteer texting program during the Bernie Sanders campaign. The platform allows online organizers to reach their audience via Twilio SMS at scale, making it easier for them to rally people behind a cause or action. With the power of peer-to-peer texting, Relay has scaled from zero to millions in 81 days and is now powering national organizations like the ACLU and political campaigns across the country. The platform's simplicity and effectiveness have made it a valuable tool for organizers, allowing them to have personal conversations with their audience at scale.
