Tessella is an international analytics, technology and consultancy firm specialising in R&D.


Tessella was founded in 1980[1] by Kevin Gell as “Tessella Support Services Plc”. Tessella moved to its first permanent office in Abingdon, Oxfordshire in 1987.[1]

Tessella opened its Warrington branch in 1998 and its Burton upon Trent branch in 2000.[1]

In 2000 Tessella opened its first branch outside the UK in Den Haag, The Netherlands.[1] In 2003 Tessella started working in the USA as “Tessella Inc” and now has offices in Houston, TX, Boston, Massachusetts and Washington DC.[1]

During 2005 Tessella purchased Analyticon.[1]

In 2009 Tessella changed its name form “Tessella Support Services Plc” to “Tessella Plc”[1] and expanded its services to include consulting.

In July 2012 Tessella announces the completion of its management buy-out, led by its existing management team. Mobeus Equity Partners supported the buyout and founder Kevin Gell retains a significant minority stake plus continues to serve as a board member. http://www.tessella.com/2012/07/press-release-management-buy-out-at-tessella/

Since the MBO, Tessella has expanded its consulting and technology services to explicitly include analytics[2] as a core capability, channeling the hi-tech experience gained supporting clients in big science, space & defense and similarly data-rich industries.
