Grant Munro started FlashStock in 2013 to help big companies produce content (photos, videos) for advertising campaigns. In 2015, Instagram exploded, and online marketers became desperate for more content, which helped fuel Munro's business from a handful of employees in 2014 to more than 100 in 2017. That's about when Munro agreed to sell FlashStock to Shutterstock for $65 million.
