Recently delisted IT recruitment firm Rethink Group (see Rethink's 'departure' confirmed) has made its first acquisition since returning to private life, that of City of London-based recruitment firm, Consort Group. Terms were not disclosed, though the Business Growth Fund, the private equity business launched in 2011 by Britain's major banks, has invested £2.5m in Rethink to facilitate the deal. It looks like BGF is in it for the long haul, anticipating further funding rounds "for organic growth and future selective acquisitions - a number of which have already been identified".Rethink had a pretty rocky time as a listed company, at one stage making the dreadful mistake of trying to incubate an enterprise content management/business intelligence consultancy under the covers (see ReThink rethinks Aiimi). Since disposing of Aiimi in late 2013 Rethink has stuck to the knitting - always the best strategy I feel.With BGF behind it, and out of the glare of the public eye, Rethink has a much better chance of establishing itself as an even more formidable player in the UK IT recruitment market.
