About us

Our history

CKEditor, which was initially called FCKEditor, was established in 2003 – a period when open source software wasn’t well-known nor widely used. Frederico Caldeira Knabben, the creator, initially considered the project as a passionate hobby. However, by 2006 he’d officially launched CKSource and began building the company and its comprehensive software offerings.

In 2018, the first stable version of the rich text editor was launched - CKEditor 5 - and in 2022, the open source version became the default editor in Drupal. To this day, CKEditor 5 continues to lead rich text editing technology, with further expansions into real-time collaboration, track changes, AI and the introduction of templates that make it easier for teams to work together to create great content.

Today, CKSource’s products are used by 100,000+ customers. Similarly, the company has grown from its open source beginnings to now being a portfolio company of its parent,Tiugo Technologies, who employs 260+ people across the world.

Our values

Drive

We are propelled forward by a never-ending desire to improve ourselves, each other, and our products.

Innovation

We are not afraid to innovate, to experiment, or to fail. We learn from our mistakes and keep trying until we get it right. We believe in doing a lot with a little and pushing the boundaries, so we can grow together.

Respect

We take pride in being transparent about our expectations and respecting each other’s ideas.

Enthusiasm

We don’t shy away from challenges. We are enthusiastic about what we do, and we have fun along the way!

Collaboration

We’re working towards a common goal and will only be successful through open communication, a willingness to help each other, and a genuine desire to do our best.

Trust

We trust each other, and we’re proud that our customers trust us.

Our culture

We care deeply about our work, our products, our impact, and each other.

As a globally distributed team, drawing from many different cultures, creeds, and contexts, we celebrate each other’s strengths and know that diversity cultivates innovation. We work hard to foster a culture of trust and feedback where everyone can grow and learn from each other, and where every voice counts. We can’t always be in the same room, but we strive to be on the same page.

We believe in being human at work, and want our people to be able to enjoy their jobs and their lives in balance. The freedom to deal with kids/pets/toothaches/in-laws/plumbers/etc. when needed means our teams are fully engaged when they’re working.
