Sean Gibson joins the Aberdeen-headquartered corporate finance firm following over six years at Deloitte where, as assistant manager and latterly manager, he gained a wealth of experience in handling complex accounting issues for ambitious businesses across the UK.

Quantify capped its debut year in 2025, advising on 23 completed deals with a cumulative deal value in excess of £280m. 2026 has already started with the firm completing financial due diligence on its first fully overseas transaction which saw HAVN Capital (HAVN), a specialist private equity investor focused on the energy transition, signing an agreement to acquire a majority stake in Spares in Motion BV, an independent wind turbine spare parts provider headquartered in Rotterdam.

This latest deal comes hot on the heels of Quantify providing financial due diligence and buyside support to long-time client and leader in social housing across Scotland, Cardo Group, on its acquisition of Faskin Group, a roofing contractor based in Paisley.

Marking a productive start to the year, Quantify has also been shortlisted for Financial Due Diligence Provider at the flagship Real Deals Private Equity Awards 2026, signalling the firm’s contribution to the European private equity deals landscape.

Melanie Clark, Partner at Quantify, commented: “We’re thrilled to welcome someone of Sean’s calibre to the team who will instantly make a meaningful impact, providing trusted corporate finance advise to our base of clients across the UK and Europe.

“We’ve had a terrific start to the year and expect this appointment to be the first of many as we continue to build a leading independent corporate finance advisory firm, offering partner-led advice across the entire spectrum of corporate finance and transaction services.”

On completing the firm’s first overseas advisory deal, Tom Faichnie, partner at Quantify, said: “We’re proud of our long-standing relationship with the HAVN team with whom we have worked with over the last 10 years.

“This latest deal represents an important moment for Quantify as it not only demonstrates our enduring ability to provide trusted support on complex private equity transactions but also helps to position our firm as a genuine European due diligence provider.”
