Who We Work With
“We recently worked with Sister London on a six-week Christmas campaign, and we couldn’t be more impressed with the results. The team is highly organised, hands-on, and strategic in their approach, always driven to deliver exceptional outcomes for their clients. Not only did they surpass their already ambitious KPIs, but they also secured coverage in key titles such as The Telegraph and the BBC, which hadn’t featured Camden Market in recent years. The team are highly professional, and they leveraged their excellent media relationships to achieve significant brand exposure for Camden Market during a highly competitive season. It was a pleasure working with Sister London, and we look forward to continuing our partnership in 2025.”
