David D’Alessandro Joins IDC as Chairman of the Board

Former John Hancock CEO to lead IDC’s board as the company accelerates its next phase of growth and innovation

BOSTON--(BUSINESS WIRE)--International Data Corporation (IDC), the trusted technology intelligence leader, today announced the appointment of David D’Alessandro as Chairman of its Board of Directors. A seasoned executive with a career spanning financial services, sports, and entertainment, D’Alessandro brings a legacy of leadership grounded in brand transformation, operational rigor, and ethical governance.

He succeeds Steve Singh, who will continue to serve as a director on the Board. Singh, the former Chairman and CEO of Concur and a former Member of the Executive Board of SAP, recently stepped into the role of interim CEO at Spotnana.

“David is a strategist, a brand visionary, and a respected leader who understands the power of data to drive meaningful outcomes,” said Genevieve Juillard, CEO of IDC. “His experience leading through complex market transitions and advising organizations through transformation will be invaluable as IDC continues its path of innovation and growth."

D’Alessandro spent two decades at John Hancock, where he rose from marketing executive to Chairman and CEO. He led the company through a high-profile IPO and its subsequent merger with Manulife Financial. Under his leadership, John Hancock became a globally recognized sponsor of events like the Boston Marathon, the New York City Marathon, and the Olympic Games. He later served as Chairman and CEO of SeaWorld Parks & Entertainment and held a seat on Major League Baseball’s Special Task Force on the 21st Century. D’Alessandro currently serves as Chairman of Encore Event Technologies.

D’Alessandro is also the author of three best-selling books on leadership and ethics in business: Brand Warfare, Career Warfare, and Executive Warfare. He owns Toscano restaurants in Boston and Cambridge and remains a strong voice on corporate responsibility and performance.

“IDC is entering an exciting new chapter,” said D’Alessandro. “The strategic divestment of Foundry — completed in March 2025 — frees up capital and focus for IDC’s core strength: delivering sharp, data-driven technology intelligence. This transition positions us to double down on innovation and AI-powered insights that empower businesses to navigate complex market shifts with confidence.”

D’Alessandro joins a board committed to supporting IDC’s mission to deliver trusted tech intelligence that illuminates the path forward for technology buyers and suppliers worldwide.
