Co-founder of Tactical Tech, Marek is a restless producer of various creative and social interventions that span across various media: radio, television and internet; as well as those that utilise non technical formats, such as workshops, book sprints and endless conversations. Activism, innovation and creativity are the major driving forces in his work, as much as the importance of marginalised voices, opinions and world views.

Previously he co-founded The Second Hand Bank, as well as the International Contemporary Art Network, before Tactical Tech and recently Tactical Studios. He is currently focusing on producing interactive and static visualisations representing complex social and political issues; very recently he produced and directed a series of documentary films for Tactical Tech called Exposing the Invisible. In some spare time he produces a radio program titled Love & Chaos on Reboot FM.
