About Justin Greenberg

With nearly two decades in the product trenches, I’ve led early-stage growth teams, R&D units, and strategic bets within large organizations, where stakes are high, and intrapreneurship fuels innovation. I’ve been on teams that endlessly pursue product-market fit and others that savor the magic of finding it and scaling rapidly.Driven by an inquisitive spirit, I help organizations navigate ambiguity, bringing cross-functional teams together and aligning them on shared goals. I'm passionate about uniting diverse teams — from engineering to design to data science — speaking their language to drive toward a common objective. My approach blends product rigor, data-driven insights, and a deep understanding of customer needs, guiding teams to create products that resonate with the market and achieve success.Some career achievements include:Driving Customer Engagement -Developed a referral program for Gartner's Peer Insights to boost stagnant user growth. This initiative leveraged existing users to attract new reviewers, increasing first-time reviewers by 35% and growing our reviewer base to over 400,000 in five years.Enhancing Revenue with AI Optimization -At Epsilon, led the creation of Scheduling Intelligence, an AI-driven tool optimizing email marketing send times. This data-driven approach improved campaign performance, increasing client revenue per campaign by 10% and earning a highlight in the company’s earnings report.Beyond work, I’m a tennis and skiing enthusiast and a passionate foosball player who nearly qualified for the Foosball World Cup. Let’s connect to discuss product strategy — or hear the story of my foosball journey!
