Prior to the launch of Aliter, Greig had been running and building successful UK support services businesses for over 15 years, with an active involvement in leveraged buyouts since 2008.
Like fellow Aliter founders Billy Allan and Andy Galloway, Greig’s early career was at E.J. Stiell which he joined as an apprentice in 1986. By the time of its sale to Alfred McAlpine in 2002, he was a Divisional Managing Director. He then became a Director of McAlpine’s Business Services division, responsible for developing and delivering its growth strategy.

In this and subsequent roles, Greig regularly negotiated major contracts worth in excess of £50m per annum and sat on various joint venture boards with FTSE 100 companies.
Greig became UK Managing Director of Emcor, before joining the buy in team at Europa Support Services as CEO in 2008. Over the following seven years he was responsible for generating significant growth – organically and through a series of acquisitions. This culminated in the sale of Europa to Bilfinger Berger in 2013.
