I’m the founder and CEO of Hootsuite, the world’s most widely used social relationship platform, with 18 million-plus users, including more than 800 of the Fortune 1000 companies. A serial entrepreneur, I started my first business in high school, ultimately opening a string of ventures—from a pizza restaurant to a digital media agency—before starting Hootsuite. Today, I love building vibrant companies with strong cultures, as well as sharing what I’ve learned on the frontlines with other entrepreneurs and business leaders. I’m the author of the Amazon-best-selling guide to social media for leaders, The $4 Billion Tweet, and I’m also a global influencer on LinkedIn, Facebook and other social networks. I’m also proud to champion youth entrepreneurship through my organization League of Innovators.
