We specialize in
custom AdTech &
MarTech platform development

Clearcode was founded in 2009 by Maciej Zawadziński and Dominik Jendroszczyk – business partners and entrepreneurs who have been doing business in the Internet industry since 2003.

Over the years, we’ve become a leader in AdTech, MarTech and data platform development.

In January 2022, we achieved another milestone by being acquired by Qinshift, a KKCG company.
