About S4 Capital

S4Capital plc is the tech-led, new age/new era digital advertising and marketing services company, established by Sir Martin Sorrell in May 2018. Its strategy is to build a purely digital advertising and marketing services business for global, multinational, regional, local clients, and millennial-driven influencer brands. This will be achieved by integrating leading businesses in three practice areas: Content, Data&digital media and Technology services, along with an emphasis on "faster, better, more efficient" executions in an always-on consumer-led environment, with a unitary structure. In 2018, S4Capital combined with MediaMonks, the leading AdAge A-listed creative digital content production company led by Victor Knaap and Wesley ter Haar and then with MightyHive, the market-leading digital media solutions provider for future thinking marketers and agencies, led by Peter Kim and Christopher S. Martin. Since then, MediaMonks and MightyHive have combined with more than 25 companies across Content, Data&digital media and Technology services. For a full list, go to s4capital.com. In August 2021, S4Capital launched its unitary brand by merging MediaMonks and MightyHive into Media.Monks. As the operational brand, Media.Monks underpins S4Capital's agility, digital knowledge and efficiency and is the next step in delivering on its foundational promise to unify Content, Data&digital media and Technology services. Victor Knaap, Wesley ter Haar, Christopher Martin, Scott Spirit and Mary Basterfield all joined the S4Capital Board as Executive Directors. The S4Capital Board also includes Rupert Faure Walker, Paul Roy, Daniel Pinto, Sue Prevezer, Elizabeth Buchanan, Naoko Okumoto, Margaret Ma Connolly, Miles Young and Colin Day.
