Gregory Harrison is a creator, former CFO, and ex-paramedic who brings an unusual combination of experience to his work—spanning finance, emergency response, and a long-standing fascination with mysteries and financial crime.

With more than 35 years leading finance teams, Greg has deep expertise in corporate finance, SaaS, AI, startups, and e-commerce. Throughout his career, he has developed a reputation for seeing patterns others miss—an instinct shaped not only by decades in accounting, but also by his time as a paramedic, where fast thinking and attention to detail could mean the difference between order and chaos.

He is the founder of ventures including HailaTable, Owlery, and ExtraOrder, and the author of the Maya Chen Mysteries series, where his interest in financial crime and hidden systems comes to life through fiction. His work consistently focuses on turning complex ideas into practical tools, engaging experiences, and creative solutions for businesses.

Greg is known for blending financial discipline with creativity, helping organisations navigate growth while staying grounded in sound strategy. He is also available for fractional CFO roles, offering experienced financial leadership to businesses that want strategic insight without the full-time overhead.
