Glenn set up Apostle in August 2025 with Mili Paligoric Garcia. The consultancy builds retention and lifecycle programs for direct-to-consumer brands, with senior people on every account. In September 2026, a year after launch, Apostle announced that it had become a Klaviyo Platinum Partner.

Before Apostle he spent four and a half years at the ecommerce agency Underground Ecom as head of client and partnerships. He ran its agency and technology partnerships, including Klaviyo. He also ran The DTC Marketing Club, a community and events business for founders of direct-to-consumer brands.

His earlier career was in marketing operations and consulting in Preston and Leyland. He holds a law degree from the University of Lancashire and sits on the advisory board of The Beauty Intelligence Project.

Outside work he is a director of a community interest company that protects Preston's historic buildings. He led the Friends of Tram Bridge campaign, which saved the city's 200-year-old Tram Bridge.
