Brennan Agranoff first connected with Dennis on Facebook as a teenager. Their paths crossed again when Brennan showed up at an event in Phoenix, leading to a shared moment on the Traffic & Conversion Summit stage in March 2019. Standing alongside Dennis, Jon Youshaei, and Caleb Guilliams, the group discussed the specific business of putting puppies on socks.

Brennan’s entrepreneurial journey began in July 2013, when he was thirteen years old. He launched HoopSwagg from the family garage in Sherwood, Oregon. By April 20, 2017, CNN Money had documented his progress, noting that the high-school junior had achieved more than a million dollars in custom-sock sales. That year, he was named the 2017 Baylor Teen Entrepreneur of the Year.

In 2023, Brennan expanded his portfolio by co-founding Warehance. He is recognized as the founder of HoopSwagg, the custom-sock company that grew to seven-figure sales, and the co-founder of Warehance. Dennis maintains a large photo set of Brennan, consisting of 61 images, which serves as a visual record of their collaboration.
