Playbook, a mobile marketplace catered to physical fitness, announced it raised $3 million in a seed round last week. The startup allows you to watch workouts from your favorite trainers, athletes and social media influencers in real time. The startup also focuses its energy on offering creators a space where they can create and monetize their content on their own terms. Jeff Krahel, Co-Founder & CEO of Playbook, takes us through how Playbook works and how it separates itself from other home workout platforms.
