Integra Sources vs Cardinal Peak: overview

Integra Sources

Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.

Cardinal Peak

Cardinal Peak has built connected devices out of Lafayette, Colorado since 2002, covering electrical design, embedded firmware, cloud back ends and mobile apps. Its longest-running specialities are audio, video and connected home products. FPT Corporation, the Vietnamese IT group, acquired it in November 2023, adding about 100 experts and a US office to FPT's North American business; Cardinal Peak now describes itself as a wholly owned FPT subsidiary. The acquisition gives it access to FPT's offshore capacity for larger programmes.

Integra Sources vs Cardinal Peak: pros and cons

Integra Sources
+ Kernel module and device driver work is a stated speciality
+ Rates make it one of the more affordable options for low-level engineering
+ Can take a product from schematic through firmware for small hardware startups
- Small team with limited capacity for parallel projects
- Little public evidence of IEC 62304, ISO 26262 or similar regulated development
- Time-zone gap with North American clients
Cardinal Peak
+ Onshore US engineers for clients who need them for IP or export-control reasons
+ Audio and video streaming firmware is a long-standing strength
+ FPT ownership adds offshore capacity when a programme grows
- Acquired by FPT in 2023, so check how much of a project will be staffed from the US versus offshore
- US rates make small firmware fixes relatively expensive
- Firmware is one part of a broader product-engineering offer
