Cambridge Consultants vs S3 Connected Health: 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.

S3 Connected Health

S3 Connected Health is the connected health business of Dublin's S3 Group (Silicon & Software Systems), which dates to 1986; the connected health unit itself is listed as founded around 2001. After the group sold its semiconductor unit to Adesto, it concentrated on this business. It works with pharma and medtech companies on connected drug delivery, SaMD, IoMT platforms, wireless connectivity and data security, and partnered with Ypsomed on connected injection devices. Employee figures range from about 200 to 300.

Cambridge Consultants vs S3 Connected Health: 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
S3 Connected Health
+ Long experience in wireless and embedded software from its S3 Group background
+ Works directly with pharma on connected injectors and inhalers, such as the Ypsomed partnership
+ Covers apps, cloud and the device connectivity module
+ Delivery team includes a site in Poland, which helps with cost
- Founding date and history are tangled with the wider S3 Group, so check which entity you contract with
- Not a mechanical or industrial design firm
- Pharma focus means pure medtech hardware projects are less common
