Built by Stefan King

I build dfine.io. Because I needed it myself.

Berlin · GermanyGmbH · since 2020

I'm a colorist. The tooling around the work kept getting in the way, so I built my own.

The story

Built straight out of the grading suite.

In post-production since 2007, with my own post house DIFFERENCE CC ↗ in Berlin since 2018. No tool kept our data in Europe honestly, so I built dfine.io. Every feature passes our post house before it reaches you.

Custom development

If the product does not fit, we build it so it does.
