Executive Directors

Stuart Alderson (CEO)

After studying Computer Science and Economics, Stuart began his IT career in Operations with STC/ICL in the early 1980s. His roles crossed manufacturing, insurance and legal before moving into finance with UBS in the mid 1990s. As Global Head of Infrastructure Project Services, he played a major part in the UBS/SBC integration, Y2K and Euro conversion programmes, and it was also at UBS where he met Stuart Tarrant. He joined ABN Amro as a freelancer in 2003 where he managed the relationship between Operations and the new outsourcer EDS, working closely with Barnaby Mote.

The following year at RBS, he fulfilled an interim management role as Chief of Staff to the Global Head of Infrastructure, supporting organisational and technology change. From there he joined a City-based consultancy in a senior account management / business development role.

Barnaby Mote (Finance Director)

Barnaby spent 10 years in investment banking IT prior to founding 4sl. He has worked for UBS, Deutsche Bank, ABN Amro and RBS. Roles he has performed include programme controller, financial controller and business manager, and his experience covers front and back office technology as well as infrastructure. Whilst at ABN Amro, he met Stuart Alderson working on a large-scale outsourcing initiative.

He has a Masters in Psychology from St Andrews University.

Stuart Tarrant (CTO)

Stuart studied engineering at UCL and complemented this with practical experience from an engineering company and a period in R&D at Sony Broadcast. His first job was with Case Communication on a pioneering mobile data communications system before moving into financial services as a systems analyst at NatWest. He helped implement an open systems architecture for the bank¹s branch network through innovative use of emergent client server technology.

Stuart delivered a number of major IT projects in the investment banking domain after joining SG Warburg in the early 1990s; the subsequent merger with Swiss Bank Corporation, the outsourcing to Perot Systems and merger with UBS provided a number of significant challenges and Stuart gained recognition as heavyweight programme delivery and service manager. He moved into consulting in 2003 with a specialist City-based infrastructure services firm and was instrumental in the development of strategic service offerings which helped grow the business leading up to its acquisition in 2007.
