Integra Sources vs Wind River: overview
Integra Sources
Integra Sources, founded in 2014, is a compact custom hardware and firmware shop with public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (roughly 24 to 51 employees, depending on the source). At this size, turnkey delivery — electronic design, PCB layout, FPGA, embedded firmware, and kernel/driver development for Windows, Linux, macOS, and Android — all under one small team is the actual value proposition: no coordinating separate hardware and software agencies, which matters more for a startup buyer than choosing between generalist scale options.
Wind River
Wind River Systems, founded in 1981 and headquartered in Alameda, California, built VxWorks, a real-time operating system certified for use in commercial aircraft including the Boeing 787 and Airbus A400M. At 1,000-5,000 people and having passed through Intel, private equity firm TPG, and most recently automotive Tier 1 supplier Aptiv (2022), Wind River is fundamentally a product/licensing vendor rather than an agency in the traditional sense — a different category from the boutique-vs-generalist agency spectrum this list otherwise tracks.

Integra Sources vs Wind River: pros and cons
| Integra Sources | |
|---|---|
| + | One team handles electronic design, PCB layout, FPGA, and firmware without the client coordinating separate hardware and software agencies |
| + | 250+ completed projects reported despite a small team size, suggesting efficient project turnover for a boutique this size |
| + | Kernel/driver development spans four major operating systems (Windows, Linux, macOS, Android), broader OS coverage than most similarly sized boutiques |
| - | Public sources disagree on both headquarters location and headcount, making delivery capacity harder to verify precisely |
| - | Small team size limits fit for programs needing multiple concurrent workstreams |
| - | No public case studies with named enterprise clients to independently verify scale claims |
| Wind River | |
|---|---|
| + | VxWorks has over 40 years of production history and is certified for use in commercial aircraft including the Boeing 787 and Airbus A400M |
| + | Deep RTOS product expertise, useful for teams that need a certifiable, widely-supported real-time operating system rather than a custom-built one |
| + | Long operating history means extensive documentation, tooling, and third-party ecosystem support |
| - | Has changed ownership multiple times (Intel, TPG private equity, Aptiv majority stake in 2022) — buyers should confirm current organizational priorities directly |
| - | Primarily a product/licensing vendor with services attached rather than a bespoke custom-firmware development agency |
| - | Public pricing and minimum engagement figures are not disclosed and licensing costs can be substantial for certified deployments |
