Stephanie Hankey is the Executive Director of the Tactical Technology Collective ( She has worked worldwide to bring design and technology together with activism and campaigning for the past twenty years. She worked to develop and support early digital campaigning for the Open Society Foundation, until in 2003 she co-founded Tactical Tech, an organisation working worldwide to help activists, journalists and NGOs use digital technologies in the work.

As a practitioner, she has worked for the last decade to build the capacity of human rights defenders, activists and journalists on effective digital activism, to defend freedom of expression and to advance digital privacy and security within civil society. In 2011, she co-founded the creative design agency for advocacy, Tactical Studios, she is the co-author of the book Visualising Information for Advocacy and in 2013 she was awarded an Ashoka fellowship for her work as a social entrepreneur.


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.
