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.

59A is a technology business built to engineer opportunity within the ever increasing complexity of media strategy, planning, and buying. We do this through the creation and deployment of custom algorithms across any programmatic, e-commerce, and social platform. Why are we called 59A? We were looking for something that represents the philosophy of our business. A book titled, ‘Exactly: How Precision Engineers Created the Modern World” depicts the development of engineering from the Industrial Age to the Digital Age exploring the single component crucial to advancement, precision. Throughout the book a theme of creativity is put forward to be as important as engineering itself when it comes to the creation of any solution. One area covered was the introduction of quartz as a capability in watches. Quartz simplified the creation by replacing complex movements and machinery, which not only made timepieces more scalable but also more accurate. In 1959 Seiko started to develop a quartz wristwatch and codenamed the project 59A. Ten years later in 1969 Seiko launched the first ever quartz wristwatch, it was the most precise timepiece ever made and revolutionised the industry forever. The project codenamed 59A is what 59A believes in: creating powerful technology that creates accurate, bespoke, futureproofed, omni-channel custom algorithms to empower the industry with technology in a significant way.
