What we do: Cognidox’s story is bound up with that of the "Cambridge Phenomenon" the so-called Silicon Fen high-tech cluster that emerged from the East of England in the 1990s (https://www.cognidox.com/blog/high_tech_product_development). Our clients have scaled and exited multiple times. We bring a way of working that allows customers to get their product to market quickly and comply with the latest regulatory standards. We started in semi-conductor and high tech product development. We are now experiencing rapid growth on the back of our move into medical devices and med tech generally. We basically enable high tech product development and medical device development companies to deal with complex development cycles involving multiple design revisions and cross-functional teams. Where we are: Our Cambridge offices are located at the Eagle Labs building on Chesterton Road in Cambridge. Parking, great coffee and ability to mix with staff from other technology businesses who are also based at the facility.
