Simple and secure mobile messaging for coworkers. Brought to you by people passionate about making communication at work easier, faster and more human.

Despite the numerous tools intended to help people communicate at work, we’re still a lot better at communicating in our personal lives. Cotap Co-Founders James Patterson and Zack Parker set out to change that by empowering employees to communicate in a way they already love — with their mobile devices.

Founded in May 2013, Cotap was born so everyone from the breakroom to the boardroom could easily have the conversations that drive work forward — fast, active, dynamic dialogue that’s meaningful.

We’re obsessed with fixing communication at work. Since Cotap launched its first app in October 2013, workers everywhere now have access to real time, secure and easy-to-use mobile messaging. Communication is at the heart of creating happy, productive and engaged employees, and we build tools to make it better.

Headquartered in San Francisco, Cotap is quickly and purposefully growing with the backing of Charles River Ventures and Emergence Capital Partners.
