About Kero
The People Behind Better Business Messaging
We started with a simple question: why is business messaging still stuck in the past? Built on 25 years of mobile messaging expertise, Kero exists to make rich, interactive communication accessible to every business.
From SMS veterans to rich messaging pioneers
For more than two decades, the Celerity Group has been at the heart of mobile messaging — building connections for thousands of businesses through A2P SMS. But as smartphones transformed how people communicate, we saw the gap widening between what customers expected and what businesses could deliver.
That gap became Kero. We built a platform that brings RCS, WhatsApp, and SMS together in one place, with intelligent fallback so every message reaches its audience. The name kero comes from the Japanese kero kero, the distinctive croak of a frog. It captures what we believe: business messages should be distinctive, not disposable.
Together with Dotgo, the global leader in RCS for Business, we deliver rich messaging solutions to businesses of every size across more than 20 countries.
Our Values
What drives everything we build
These aren't words on a wall. They shape every feature we ship, every conversation we have, and every partnership we build.
Ship it simple
Rich messaging shouldn't require a dedicated team. We obsess over making powerful features accessible to businesses of every size.
Earn trust daily
WASPA, TEM, and MEF certified. We hold ourselves to the highest compliance and security standards because your customers' data deserves nothing less.
Customer-first, always
Our success is measured by yours. Real people answer your questions, and your feedback shapes our roadmap.
Move with the market
RCS, WhatsApp, and whatever comes next. We stay ahead of messaging standards so you never have to scramble to catch up.
Messages worth reading
We believe every business message should be as engaging as a personal one. Rich, interactive, and built to spark real connection.
