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 things are deeply ingrained as values in our company’s culture and DNA. To this day, we are remote-only, and 80% of our revenue is spent on open source development and fostering its communities. Our open source projects (Tus and Uppy) are changing how the world does file uploading.

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 thirteen years.

But we always strive to be better. So, together with 16 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.

  • January 2009

    The first commit

    First paying customer

  • December 2010

    Realtime encoding is launched

    This feature is an 🥇 industry first and gets coverage on the AWS blog. Being among, or maybe the actual first to run Node.js in production was risky, but paid off in the end.

  • May 2012

    We're now ramen profitable

    This means we could live off of Transloadit if we'd be okay with a diet of ramen noodles.

  • June 2012

    We start tus.io

    We start tus.io

    Fed up with reports of broken uploads and HTTP only caring about resumability of downloads, we take the first swing at an open protocol for resumable file uploads (an 🥇 industry first).

  • April 2014

    MTV Europe becomes a customer

    Besides significant traffic, this name gave us the credibility that allowed us to reel in new customers.

  • July 2014

    Revenue nearly doubles

    We no longer need to do consultancy work on the side. Kevin and Tim now both work fulltime on Transloadit. Felix left the company three months earlier and started consulting for Apple.

  • May 2015

    The New York Times becomes a customer

    Their name and logo add credibility to our service. They also challenge us to thoroughly review (and improve) our legal framework.

  • October 2015

    We start Uppy

    Initially, we thought to build a proprietary uploader and posted a job ad for it. We then decided that this project needed to be open source and announced Uppy eight months later.

    Our new recruits for the Uppy projects push the counter into double digits.

    We call it The Dev Times and each month, it brings you three general dev and two Transloadit updates.

  • March 2019

    Transloadit GmbH is founded

    Transloadit GmbH is founded

    Weary of the possibility of a hard brexit and its potential dire consequences, we flee the UK. Transloadit continues on as a German limited liability company.

  • April 2019

    🐶 Uppy hits 1.0

    The launch is well received and gets love on Hacker News, Reddit 1 2 3 4, Smashingmag, Product Hunt and Javascript Daily. It also reaches ⭐️ 20k+ stars on GitHub.
