Semaphore was originally created to local startup 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.

SMS is still the way to cut through saturated email inboxes and deliver a personal touch, but we’ve also seen companies come up with other ingenious uses for Semaphore. At Semaphore, we’re always on the lookout for companies building cool things. And we can’t wait to see what you’ll dream up next.
