S4 Capital has appointed Christopher S. Martin as chief operating officer and Colin Day as new chair of audit and risk committee.
Both will take on the roles with immediate effect and the company said their appointments were part of plans to scale S4 capitals organisational structure and processes, along with intentions to invest in and “tighten” financial control, risk and governance processes.
Martin was a co-founder of MightyHive Inc, which joined S4 Capital in December 2018 after being fully merged with Media.Monks in 2021. Prior to this he worked at Yahoo for more than ten years.
Day will also join the S4 Capital board as a non-executive director and has held management and governance roles in the past including non-executive chairman of Premier Foods, chief executive of Essentra and chief financial officer of Reckitt Benckiser and Aegis.
