About us

Your web & app agency in Berlin

Late 2017 developer freelancers Korneliusz Caputa and Carl-Petter Bertell decided to do what they never wanted to do again - work for an agency


We had seen our share of agency work. More than a decade on average. This time it was different though. It was our agency and we could make sure its values were aligned with delivering value to our clients.

A few months later Makers' Den GmbH was open for business, and some time after that the actual Den, i.e. our first office in Berlin was opened.

We prefer to work in small tight-knit teams with our own people and select freelancers we know and trust, either on-site in Berlin together with client teams, or in our den. It makes communication easy and keeps overhead low.

Our existence is staked on your success. We're doing what we love and we're ok with our reputation being based on the quality of our work.

- Korneliusz & Carl

The T-shaped maker

We value having diversity in our people, but moreso we value that they have diverse talents themselves.

We don't have persons that just do one thing. They'll do one or two things better than most on this planet, but in general their skillsets are wide enough to comprehend the complex contexts of our clients and are able to contribute far beyond their advertised expertise.
