Danny Leffel

Danny Leffel is a founder, operator, and CEO with a track record of both building companies from the ground up and scaling established platforms. As CEO of Roo, he is transforming veterinary staffing through technology and data-driven execution.

Previously, he founded and led Crew, a workplace communication platform acquired by Square, and held leadership roles at eBay, where he focused on category management. Whether launching new ventures or driving growth at scale, Danny thrives at the intersection of technology, operations, and marketplace dynamics — often with his two foster-fail cats, Mosey and Fea, making an unscheduled appearance on his video calls.
