The Team
We built ejabberd in 2002 and we still maintain it. We scaled it for WhatsApp, Nintendo, and the BBC, and we have been doing this kind of work for over 25 years.
Founder & CEO
Mickaël Rémond founded ProcessOne with a single conviction: critical communication infrastructure belongs to the people who depend on it, not the vendors who rent it. He has spent his career on distributed systems and open-source software, working from the position that real-time messaging at scale succeeds or fails on its technical foundations.
Under his leadership, ProcessOne built ejabberd, the open-source XMPP server that powered WhatsApp's growth from zero to two billion users. The same technology went on to serve Riot Games, the BBC, Nintendo, and hundreds of other organizations worldwide. Mickaël has worked directly with many of these clients, helping them architect messaging systems that combine massive scale with security, resilience, and operational control.
Mickaël is an active contributor to the XMPP Standards Foundation, working on the protocols that let organizations own their communications stack rather than rent it. His bets on technology have held up: he picked Erlang for fault-tolerant messaging in 1999, and two decades of industry churn later that is still the right answer.
Beyond engineering, Mickaël is a writer and speaker. He talks about decentralized communication at technology conferences, and writes short stories and novels about the futures the technology might produce.
Our engineers have years, and in many cases decades, of hands-on experience in real-time communication and large-scale messaging. We have built and maintained platforms that serve millions of users every day. The work we like best is the difficult part: making a system hold up under load, and making it hold up when something breaks.
When you work with ProcessOne, you are working with the team that built the foundation and knows every layer of it.
Communication tools have to be federated and open, or they do not last. Closed systems create dependencies you cannot unwind: when the vendor changes direction, your users have nowhere to go. Every architectural decision we make reflects that.
We do not chase technology trends that lack real-world validation. We chose Erlang in 1999 because it was the best tool for scalable, fault-tolerant messaging. More than 25 years later, that decision is still paying dividends. We invest in foundations, not fashions.
Your messaging infrastructure should answer to you, not to a hyperscaler, not to a vendor's terms of service, and not to a startup's runway. We build systems that organizations can deploy, audit, and control entirely on their own terms.
ProcessOne is privately owned and self-funded, built entirely on the trust of our customers since 1999. No outside investors, no acquisition pressure, no pivot risk.
Our priorities have always been, and will remain, aligned with the people who depend on our software.
Whether you are evaluating ejabberd for a new project, considering the Business Edition, or looking for a team to design and deploy messaging infrastructure at scale, we would like to hear from you.
