D’Alessandro’s appointment follows the strategic divestment of Foundry to Regent LP in March 2025, allowing IDC to focus on its core strength of delivering data-driven technology intelligence. “David is a strategist, a brand visionary, and a respected leader who understands the power of data to drive meaningful outcomes,” said Genevieve Juillard, IDC CEO. “His experience leading through complex market transitions will be invaluable as IDC continues its path of innovation and growth.”
With two decades at John Hancock, D’Alessandro rose from marketing executive to Chairman and CEO, leading the company through a high-profile IPO in 1999 and its $10.4 billion merger with Manulife Financial in 2004. He elevated John Hancock’s global brand through sponsorships of the Boston Marathon, New York City Marathon, and Olympic Games. He later served as Chairman and CEO of SeaWorld Parks & Entertainment and contributed to Major League Baseball’s Special Task Force on the 21st Century. Currently, he chairs Encore Event Technologies and owns Toscano restaurants in Boston and Cambridge.
D’Alessandro’s three best-selling books—Brand Warfare, Career Warfare, and Executive Warfare—cement his thought leadership in corporate responsibility and performance. “IDC is entering an exciting new chapter,” he said. “The strategic divestment of Foundry frees up capital and focus for IDC’s core strength: delivering sharp, data-driven technology intelligence.”
