Cambridge Consultants vs Simbex: 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.
Simbex
Simbex was founded in 2000 in Lebanon, New Hampshire, and works on product design, applied research and commercialization in medtech, health tech and sports technology. Riddell, the American football helmet maker and a long-time client, acquired it in April 2024. Its medical work includes RestEaze, a remote monitoring device for sleep disorder diagnosis built with Tanzen Medical, and fall-detection wearables. Team size estimates range from 11 to 100.

Cambridge Consultants vs Simbex: 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 |
| Simbex | |
|---|---|
| + | Strong sensor and biomechanics research skills |
| + | Experience with wearable monitoring devices |
| + | Covers design through commercialization planning |
| + | Small team with direct access to principals |
| - | Owned by Riddell since April 2024, so sports technology may take priority over medical clients |
| - | Small team |
| - | Fewer regulated Class II and III device credits than medtech-only firms |
