About Us

Evolution of Excellence in Communication. Tracing Openwave's journey from pioneering email systems to modern B2C communication platforms.


Our Journey and Beyond

Since the mid 90s through and Critical Path, Openwave have been at the forefront in building, delivering and managing some of the largest email systems in the world for Communication Service Providers. As the market grew from the infancy of the internet to today where we live in a fully connected online world, email has remained at the forefront as one of the most mission critical services with your email address being a unique digital identifier for engaging online. Today Openwave has hundreds of millions of registered users running on our software across the globe. As the market evolved and with the advent of rich communications, we introduced our B2C Campaign Management Platform for businesses to reach and engage end users on RCS/SMS/email channels. Openwave launched the first cross carrier rich messaging platform with the Japanese Operators branded as +Message platform which now has close to 40M users.

Openwave provides the software for the largest Communication Service Provider deployments in the world. Our systems are trusted and secure, performant, highly available and in partnership with our customers have not been compromised or hacked over the last 25+ years.
