FAQs
Facts Operator Candidates Should Know About Us
George leads Quadrillion as CEO and Managing Partner. He has served in multiple interim executive roles (Interim Chief Transformation Officer, Interim Finance Lead, Interim CIO, Interim COO) across PE-backed and public companies in technology, manufacturing, and industrial sectors. Named delivery includes ConvergeOne ($100M EBITDA captured in 9 months as Interim Chief Transformation Officer), NVIDIA, American Express, ON Semiconductor, and Synaptics. He is the author of Decipher and Deliver, the book detailing the QP methodology, due summer 2026.
Operator-led means senior Quadrillion partners run sprints from inside line roles, not from advisor seats. Typical seat patterns include Interim COO, Interim CIO, Interim CFO, Interim Finance Lead, and Interim Chief Transformation Officer. The partner has decision rights, P&L accountability, and team leadership for the duration of the sprint. They own the EBITDA, cash, or growth target the sprint is built around. The model is the core differentiator vs. consulting firms (who recommend) and staffing firms (who place).
An Interim Chief Transformation Officer is a senior operator placed into a portfolio company or public company for a defined period to lead a value capture program. The role typically owns EBITDA, working capital, and operating model targets across functions. It is most common at PE-backed companies in the first 12 months post-close or at public companies under activist pressure. Reference outcome: $100M in EBITDA value captured at ConvergeOne (a $1.6B IT networking services and OEM company) over 9 months in this exact role.
