Get 30 proven strategies to grow and optimize your email list FREE >> "Quantity leads to quality, but when you find a winner, you have to double down." - Dave Kline, MGMT Playbook Dave Kline went from leading teams at Bridgewater to building a million-dollar creator business - with zero prior experience on social media. But the real secret behind the success? His wife, Marsden (Mar). While Dave built a public-facing brand on Twitter and LinkedIn, Mar worked behind the scenes to shape the vision, voice, and strategy of their business. Then, she stepped into the spotlight. In just five months, Mar grew her LinkedIn following from 0 to now over 74,000 - outpacing Dave’s own growth trajectory. Together, they’ve built a powerhouse content engine, a six-figure cohort-based course, and a 40,000+ subscriber newsletter - all without a big team or flashy tech stack. In this episode, we dive into how Dave and Mar got started, the pivots they made (including why Mar had to force Dave into launching a newsletter), and the systems they’ve built to keep their creator business lean and profitable. Join us as we go behind the scenes with the duo behind the MGMT Playbook.
