Fractional Chief Information Security Officer (CISO)

ApprovalMax is redefining how finance teams manage the Money Out cycle — from purchase orders and supplier bills to employee expense management. Trusted by 18,000+ businesses worldwide, our platform empowers companies to automate financial controls, ensure compliance, and scale efficiently.

At the end of 2024, ApprovalMax secured a £10 million growth investment from Yttrium, a leading European technology investor. This funding marks the beginning of a new chapter in our journey — scaling our category leadership in Money Out automation, expanding enterprise capabilities, and accelerating product innovation.
