Mr Aitken brings nearly 25 years of experience from Big Four firms to his role. He will be responsible for evaluating potential portfolio companies, identifying new investment opportunities, and leading the financial strategy for Ventex.

Aitken’s previous roles include transaction services director at KPMG and two decades at PwC, both with a focus on energy sector deals. He will collaborate with finance director Lesley Barrie.

Ventex managing partner Steven Gray said: “From the outset we identified Rob as the perfect fit as our CFO, and we are delighted to now have him onboard.

“Rob brings network, diligence and financial structuring skills to Ventex that will accelerate our mission; he also gives our portfolio companies a world class CFO standing at their shoulder.”

Fellow managing partner Stuart McLeod added: “We have a unique opportunity in the UK energy sector, where political opposition to oil and gas has made it challenging for supply chain companies to access the capital they need to invest in the skills and technology needed to serve new clients in renewable energy.

“Rob’s strategic financial guidance will be critical in managing our rapid expansion and ensuring stability for our hypergrowth ambitions. I am delighted to have him onboard.”

Ventex has already completed its first two investments, Aberdeen-based HPR ROV and decommissioning-focussed artificial intelligence firm Rahd AI, which is headquartered in Perth, Australia.
