About Jacob Castellani

Over the past 25 years, I’ve had the privilege of leading strategic transformations for multinational organizations, helping HR, Finance, and IT teams deliver lasting success.

I bring structured leadership, risk-focused governance, and an unwavering commitment to achieving results — but also a human approach: clear communication, true collaboration, and integrity at every step.With over 25 years of experience leading complex HR, Finance, and Workday initiatives, I help organizations deliver critical projects with precision and confidence. Having successfully managed 40+ international Workday deployments — from strategic expansions to high-pressure recoveries — I bring a leadership style built on structure, trust, and results.

My mission is simple: to guide businesses through complexity, stabilize what feels uncertain, and deliver tangible outcomes that enable long-term success.

Whether recovering a distressed HRIS deployment or scaling Workday solutions across 20+ countries, I am committed to leading with integrity, foresight, and practical action.
