John Glencross


John has been a director of Terrain since the company was founded in 2009 to represent the interests of the shareholders, being wholly owned by funds under the management or advice of Calculus Capital.

John co-founded Calculus Capital in 1999 and structured and launched the UK’s first HM Revenue & Customs approved Enterprise Investment Scheme (EIS) fund. Since that time he has successfully launched and closed eleven further EIS funds and two VCTs. His professional experience spans private equity, investment banking and corporate restructuring and he has invested in, advised on or negotiated more than 100 transactions. Prior to founding Calculus Capital he was an Executive Director in the Corporate Finance Division of UBS Securities for nine years where his extensive experience covered advising on mergers and acquisitions, Initial Public Offerings, restructurings and recapitalisations, strategic alliances and private equity. He was previously a consultant for Deloitte Consultancy Division and was subsequently a founding member of the Corporate Finance Division of Deloitte Haskins and Sells.

John's first EIS qualifying investment in 1996 was in Bedford Interactive Processing Services Limited, which provided geophysical analysis services, primarily the production of detailed geological sections using 2D and 3D analysis. The company was subsequently sold to Houston based TGS Nopec which carries out geophysical surveys, achieving a return of 3.1X original investment. Whilst with Deloitte, he was seconded to the Abu Dhabi National Oil Company for Distribution (ADNOC FOD) in Abu Dhabi where, inter alia, he wrote the Management Operating Procedures manual. He has made investments in the energy, alternative energy and oil services industries.
