Tomáš Rychecký

CEO of STEM/MARK

Tomáš has experience in managing financial institutions and providing consultancy to both commercial and non-profit sectors. He enjoys thinking and staying active. He regularly challenges himself with uphill runs, while cycling is for him more about unwinding, saving time, reducing stress, and doing his bit for the environment. Tomáš took over STEM/MARK from Jan in September 2024 and is excited to develop it further, focusing on new technologies and data trends.

Jana has gained experience in both field operations and production at STEM/MARK, and prior to her current role, she spent several years in client service.

In both work and leisure, she is most often accompanied by black coffee and an even darker sense of humour.
