Cambridge Consultants vs Flex Health Solutions: 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.

Flex Health Solutions

Flex Health Solutions is the healthcare division of Flex Ltd. and operates as a contract development and manufacturing organization (CDMO) for medical devices and pharma. Flex lists 26 manufacturing sites, six design and engineering sites, 16 FDA-registered entities and 21 ISO 13485 sites for health (per company website; independently unverifiable). In 2025 it opened a North American new product introduction (NPI) center for healthcare customers, and it shared a 2025 PDA Drug Delivery Innovation Award with Merck KGaA for an autoinjector.

Cambridge Consultants vs Flex Health Solutions: 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
Flex Health Solutions
+ Large global network of ISO 13485 and FDA-registered sites
+ New NPI center supports prototype builds, design verification and production transfer
+ Award-winning drug delivery work with Merck KGaA
+ Handles sterilization and packaging in-house
- Development work mainly exists to feed programs into Flex factories
- Better for funded programs with a clear path to volume
- Site counts are company-reported and differ across Flex pages
