About Starcount
Starcount is fast-building a reputation as one of the most exciting, innovative audience data products in the market. We are delivering significant performance uplifts for our partners.
In an industry of commoditised data where everyone has access to the same signals, Starcount gives clients a unique advantage: the ‘Why’ intelligence layer. The ultimate competitive advantage isn't just knowing what someone bought; it’s knowing why they bought it. Starcount exists to reveal these hidden motivations by bringing together fragmented data across online web behaviours, banking spend transactions, and telco movement. We don't just find shoppers; we reveal their reasons for choosing every brand so our clients can deliver high-performance outcomes across every channel.
We are an independent challenger business, quickly scaling across media agencies, media owners, and brands directly. Our data is applied across omnichannel campaigns, including Out-of-Home (OOH), Connected TV (CTV), digital, paid social, mail, and CRM.
We are a small but growing team based in Liverpool Street, London.
The Role
We are looking for a Customer Success Manager who enjoys making sense of data, understanding audience behaviors and helping clients make better decisions for their media campaigns. This role offers the opportunity to work with a talented team and manage a great mix of clients. It is a superb opportunity for someone ready to accelerate their career in an ambitious, fast-growing data business.
We are looking for someone committed to delivering excellent value and service to clients, who is excited by the power of data-driven insight to make a tangible difference to campaigns.
Key Responsibilities
Marketers often struggle to translate great insight work - usually built from claimed surveys - into actionable media. Starcount bridges this gap.
