Getting a regulated medical product to market requires more than great hardware. Engineering teams must simultaneously manage embedded software, cybersecurity, QMS documentation, and validation – keeping all of it aligned around a single certified, long-term-reliable product. That is precisely the challenge a new Variscite and NRG partnership is designed to address.
Variscite, a leading System on Module manufacturer with proven expertise in medical applications, has joined forces with NRG, an engineering firm specializing in regulated medtech systems, to deliver an integrated hardware-software solution for companies building embedded medical products. The partnership gives development teams access to both a proven hardware platform and the software and engineering capabilities needed to support regulated development goals and product readiness.

The global component crisis is forcing embedded teams to confront an uncomfortable reality: not all SoM vendors are equally equipped to weather it. In the latest episode of the Embedded Executive Podcast, Variscite CEO Ohad Yaniv joined Rich Nass of Embedded Computing Design to discuss what it takes to keep customer projects on schedule when supplies are under sustained pressure and why the answer starts with who controls your manufacturing. Unlike vendors who rely on subcontractors, Variscite designs and manufactures its entire System on Module portfolio in-house, with production fully certified to ISO 9001, 13485, and 27001 standards.
