MessageBird
Founded in 2011, MessageBird is the Amsterdam and San Francisco-based cloud communications platform offering a suite of Cloud Communications APIs that enable developers and enterprises to communicate with customers all over the world. Bootstrapped since its founding, MessageBird closed the largest investment into a European software business with its Series A funding in late 2017 with $60 Million in capital from US-based Accel Ventures and UK-based Atomico.
