An operator, not just an advisor.

HRX Advisory is founded on a simple belief: the most valuable advisors are those who have done it themselves. Mark Horrocks brings over two decades of executive leadership across PE-backed and corporate environments, spanning P&L ownership, SaaS transformation and board-level governance.

This isn't strategy from the sidelines. It's leadership and advisory from someone who has navigated the complexity, made the decisions, and delivered the results.

"The gap between strategy and execution is where businesses lose value. My role is to close that gap — permanently."

Discovery

Engagement
Clear scope, defined outcomes, and a working relationship built on directness, trust and accountability, whether interim or advisory.

Delivery
Hands-on execution and oversight through to completion. Measurable outcomes, not presentations. Value realised, not theorised.
