About Transloadit

Transloadit is an MPaaS (Media Processing as a Service) for developers. Companies integrate with us to automate workflows of video encoding, image resizing, and much more.

Transloadit was bootstrapped in 2009 by three engineers hailing from Berlin and Amsterdam.

Since we met through open source and had to work remotely from day one, these principles are deeply ingrained as values in our company’s culture and DNA. To this day, we are remote-only, and we allocate $34,566 of our revenue each month to supporting open source development and fostering its communities. Our open source projects, Tus and Uppy, are changing the way the world handles file uploads.

As a teammate, you’ll find that open, remote, friendly, and curious are words that describe our company’s culture well. Much of our focus is on employee satisfaction. As we see it, this is what allows us to create the best products. Along with our guiding principles of secure, robust, performant, and versatile, this has paid off in uptime and customer satisfaction over the past fourteen years.

But we always strive to be better. So, together with 17 Transloadians, we work relentlessly to grow, nurture, and mature our company and the value it can bring into this world. Here are some of the milestone achievements that are particularly dear to us:

  • January 2008
    Debuggable Ltd is founded

    Debuggable Ltd is founded

    Tim and Felix found Debuggable, a web consultancy in Berlin. They both become core contributors and active community members to CakePHP. Three months later, Felix meets Kevin (who lives a six-hour train ride away in Amsterdam) through his open source project Locutus. The idea for Transloadit is kicked around via email before we decide the three of us should team up.
