What is Semaphore?

Semaphore was created to help Kickstart portfolio companies integrate quality SMS functionality without dealing with cumbersome Telco contracts and minimums. We opened the service to the community at large because we believe in innovation. And innovation comes when everyone (even the little guys) has the right tools to act quickly and effectively.
