The company delivers services to clients across the life sciences, energy and chemical, environmental, instrumentation, manufacturing and engineering, transport, utilities, and public sectors
Tessella Support Services has completed the acquisition of Analyticon, which is now a wholly owned subsidiary of Tessella.
Tessella is a provider of custom software to solve scientific, technical and engineering problems.
The company's 140 staff, based at offices in the UK, the USA, and the Netherlands, deliver services including software design and development, IT consultancy, infrastructure support and project management.
Analyticon specialises in the design of software requiring mathematical modelling, analysis, and creative thinking.
It says its engineers work by developing a fundamental understanding of a client's problem in a 'big picture' context, such that proposed solutions fit with the needs of the client's business.
Analyticon serves blue-chip companies, government bodies and international organisations, and is especially strong in the space and defence and the life sciences sectors.
Commenting on the announcement, Kevin Gell, managing director of Tessella, said: "Tessella has a proven 25-year history of excellence, adding value to demanding public sector and commercial R and D based organisations.
"Analyticon's services dovetail exceptionally well with our own, and the expanded group will continue to use its unique blend of scientific, engineering and IT skills to solve the most complex of technical and business problems in a highly cost-effective way".
Peter Townsend, commercial director of Tessella, said: "We have ambitious plans to expand both organically and through acquisition.
"Tessella is approximately five times the size of Analyticon, and hence this step is a bold but controlled expansion step for us to take.
"With great synergies between the skills and experience of both sets of staff we anticipate a busy future".
Kevin Gell continued: "Tessella's ability to understand and solve our clients' business and technical problems is based on the scientific and engineering excellence of our staff.
"The similarity in the backgrounds of the staff of the two companies is remarkable.
"All of Tessella's revenue earning staff have good numerate degrees, as do Analyticon's.
"There are differences though.
"Tessella technical staff are primarily software engineers with a numerate background.
"Analyticon's staff are primarily analysts and modellers who use computing tools as part of their work.
"We see these differences as strengths.
"We can use Analyticon's skills to develop new solutions for existing Tessella clients, and use Tessella's skills to provide a wider set of services to add value to the businesses of existing Analyticon clients.
"I look forward with confidence to a bright future serving the needs of an expanded list of world-class clients".
Analyticon's founder Steve Colling will work with Tessella over the next three months to ensure a smooth and orderly handover.
In the immediate term, Kevin Gell will work with Steve Colling, and senior technical staff in the company, to develop new business with both existing and new clients within the space and defence sector.
Lawrence Hopkins, associate director for Tessella's Cambridge and Stevenage offices, will manage new business development activities with Analyticon's life sciences clients.
