What We Believe

Business doesn’t get done without communication.
That’s why we believe that business communications shouldn’t only be powerful. They must also be easy and intuitive to use.

We believe that you should have it all. Not only should your communications solution offer simplicity. Choosing an ESI solution gives you a competitive edge – whether you select a cloud, on-premises solution or a mix. You can’t go wrong with ESI.

"Technology is everywhere, yet most users don’t leverage the full power of these solutions to drive business. Features and functions meant for productivity are simply too complicated and therefore go unused.

At ESI, our focus is on making intelligent technology that is intuitive and easy to use, empowering employee productivity to fuel customer satisfaction."
-George Platt, ESI CEO
