Tessella was an international analytics and data science consulting services company owned by Capgemini.

Tessella purchased Analyticon, a technical consultancy in the space and defence industries, in 2005.

[4] Mobeus Equity Partners supported the buyout and founder Kevin Gell retained a significant minority stake and continued to serve as a board member.

After the MBO, Tessella expanded its consulting and technology services to explicitly include analytics[5] as a core capability.

On 1 April 2022, Tessella ceased to be its own legal entity and is now fully integrated within Capgemini Engineering as the Hybrid Intelligence team.
