"There is a worldwide shortage of reliable, high-quality project finance modelling capability. AI can close that gap, but only if it meets the consistency, standards, and governance our industry demands.
PFI is partnering with Cellori to deliver exactly that, and to prepare modellers for a fundamentally new way of working"
