Sagentia Defence: A New Era for the Former TP Group

Sagentia Defence is the new name of TP Group. This name change is part of a wider repositioning of TP Group and its sister consultancies under a single R&D consultancy brand: Sagentia. The rebrand marks a strategic integration of more than 300 consultants whose experience spans defence, aviation, medical, consumer, food and beverage, energy, and industrial markets.

Tom Rasmussen, Managing Director at Sagentia Defence, says the development represents an expansion of capabilities, which will unlock additional benefits for clients.

As the sector navigates the technological complexities of future military threats, it’s important to harness skills and insights from beyond the traditional realms of defence. Joining forces with our sister consultancies takes our offering to an entirely new level. In addition to our long-standing expertise in operational analysis, system engineering, safety engineering, and programme delivery and support, with our extended team we are now able to offer technology creation and product development through the technology readiness levels, from early-stage research to validation and deployment.
