Beyonce has always given off the impression of a force of nature.

Yet it takes a village to run a multifaceted pop empire of that size, and Callahan-Longo is in charge.

As general manager of New York-based Parkwood Entertainment, Beyonce’s management and entertainment entity, Callahan-Longo helped maintain momentum from the greatest sneak-attack release in recent music history with Bey’s self-titled 2013 visual album (which sold 5 million copies worldwide), as well as her 2014 summer stadium tour with husband Jay Z that grossed $109 million to become the fifth biggest tour of the year, according to Pollstar.

Last fall, Parkwood pacted with British fashion house Topshop for a new apparel brand.
