We let you communicate with your customers better

From Wavecell to 8x8 – Our Story

Ten years ago, Wavecell’s CEO and co-founder, Olivier Gerhardt, recognized that telecom operators and enterprises needed someone to bridge their communication gap. What began as a self-funded venture to do just that has become a multicultural team of 80 people working in 5 countries across Southeast Asia to simplify real-time cloud communications.

Just last year, we were recognised for the difference we’ve made in cloud communications in Asia, and joined the 8x8 family to provide a holistic cloud platform globally – with chat, video conferencing, contact center and APIs.

In a world where “customer-centric” has become a trendy buzzword, we’re proof that talking to your customers—as simply and clearly as possible—is no trend. It’s the key to growth.
