From a first thought to a powerful tool: the growth of Yellenge
What started as a smart solution for a single event evolved into a complete platform for organizers who want to keep control and seek for innovation.
A journey of code, coffee, and customer conversations. Always evolving, always together with the people we do it for.
Ronnie and Joost grew up in the same village and there was an instant connection. They have stayed in touch ever since. Years later, they turned out to be the perfect combination: one with the ideas, one with the code.
While organizing a conference, Joost and Ronnie realized they could do things smarter. No more Excel sheets or endless emails. They built their first tool that combined agendas, speakers, and updates. Practical and promising.
What started as a tool for our their own events is increasingly being requested by other event organizers. They see opportunities. The platform is becoming more stable, easier to scale, and ready for growth. Yellenge is now being made accessible to other organizers.
We’re developing modules for registration, ticketing, and session picking. Everything with real-time updates and automatic integrations. Event managers gain an overview, participants gain clarity. The foundation of the CMS is becoming increasingly robust. Joke’s arrival brings new energy. With her strategic perspective and people skills, Yellenge keeps growing. Not just as a platform, but as a partner for event managers. We’re building Yellenge Assist, training courses, and personal guidance. Technology remains important, but people are truly at the center of everything.
The pandemic is forcing events to rapidly go digital. Yellenge is developing new tools for online interaction, hybrid formats, and smart check-ins. The platform is accelerating, as is the team’s growth. New clients, new use cases, new insights.
With Yellenge, you create your ideal event stack. Use only what you need, or all-in-one. From registration to app. From interaction to analysis. Everything connected, everything in real time. Event managers gain peace of mind, control, and impact.
We keep building better events. Together with our users. Together with you. Because the best features are born where technology and practice meet. We listen, develop, and improve. And we’re always there for you.
