In 2014, Alex Macdonald co-founded Velocity Black, a global digital concierge service for affluent clients. Unlike the basic concierge services of some credit cards, Velocity Black leverages technology and expert knowledge to curate personalized services such as travel, entertainment, shopping, and dining, accessible directly from your phone.

By 2022, the business had expanded to $30 million in net revenue, attracting attention from potential buyers including Capital One which acquired Velocity Black for a reported $297 million.
