Microsoft Dynamics recruiter Nigel Frank International has raised £22m from equity firm ISIS Equity Partners and HSBC Bank, with ISIS taking a 35% stake in the company.

Tim Evans, managing director of M&A advisory firm Boxington Corporate Finance, says the deal demonstrates that “private equity remains in the market for the very best recruitment sector investment opportunities”.

Evans adds: “Sector specialism and overseas operations of scale are must-haves, for which Nigel Frank is a perfect case in point.”

Founded in 2006 in Newcastle, Nigel Frank now has offices in London, Melbourne, New York, San Francisco and Singapore.

Its co-founder and chief executive officer Sean Wadsworth says the deal leaves ISIS “ideally positioned to support us as we look to open new territories and markets both by organic growth and acquisition”.

ISIS owner Adam Holloway and investment director Xavier Woodward join the board of Nigel Frank, as does new chair Stephen Ross, who has also held the chair at technical recruiters Huntress Holdings and NES Global.

•Last week, recruiter.co.uk reported that ISIS backed a management buy-out at executive recruiter Armstrong Craven.
