As the mobile app lead at McKinsey & Company, Jeffrey shapes the product strategy for the McKinsey Insights app and leads the execution of acquisition, engagement, and retention initiatives—all informed by his deep-dive analysis of five years of performance data. Before McKinsey, he grew off-platform audiences and helped set an all-time record for social traffic at The Wall Street Journal. He also managed the homepage and apps at CNN, programming desktop and mobile platforms and push-alerting breaking news and features to millions worldwide. Inspired by the “Great Rethink,” Jeffrey transitioned to a role that brings together his core passions—product, content, audience—and demands seasoned stakeholder navigation, creative problem-solving, and the agility to lead through complexity.
