Cambridge Consultants vs Key Tech: overview
Cambridge Consultants
Cambridge Consultants has done contract research and product development from Cambridge, UK, since 1960. It became part of Capgemini through the 2020 acquisition of Altran and now sits within Capgemini Invent, with a headcount of about 900 to 1,000. Medical and life sciences is one of its main sectors, and its public work includes the optics behind Ellume's FDA-authorized COVID-19 home test. Projects tend to involve new sensing, surgical robotics, drug delivery or diagnostics technology rather than incremental redesigns.
Key Tech
Key Tech (Key Technologies Inc.) was founded in 1998 in Baltimore, Maryland. It is ISO 13485 certified and works on medical device development, in vitro diagnostic instruments and consumables, drug delivery systems and human factors engineering, with an earlier client list that includes Becton Dickinson, GE, Thermo Fisher and Abiomed. Co-founder Jenny Regan handed the CEO role to Alex Flamm. The most recent public headcount we found was around 75 designers and engineers, which may now be higher.

Cambridge Consultants vs Key Tech: pros and cons
| Cambridge Consultants | |
|---|---|
| + | Rare breadth of science and engineering disciplines for early, risky technology work |
| + | Public medtech credits such as the Ellume home-test optics |
| + | Backing of Capgemini gives access to digital and manufacturing partners for later phases |
| + | Strong at feasibility studies that tell you whether an idea can work before you fund a full program |
| - | Owned by Capgemini since 2020, so pricing and processes follow a large-group model |
| - | Among the most expensive options on this list; small startups often find the minimum budget too high |
| - | Best at invention and early development; routine sustaining engineering is not where it adds most value |
| Key Tech | |
|---|---|
| + | Strong record in diagnostics where instrument, consumable and assay have to be developed together |
| + | ISO 13485 certified quality system |
| + | Human factors and usability engineering are in-house |
| + | Named work with large medtech and life science companies |
| - | Public headcount data is dated, so confirm team capacity for large programs |
| - | No volume manufacturing |
| - | Little public evidence of SaMD or cloud platform work |
