Sunrise Labs vs Plexus: overview

Sunrise Labs

Founded in 1992 by MIT-trained engineers, Sunrise Labs is a privately held product development firm that now operates from Bedford, New Hampshire, with a Boston-area office added in 2022. Its work concentrates on electromechanical medical devices: infusion and fluid handling, diagnostics instruments and therapeutic systems that combine motors, sensors, electronics and embedded software. Directory listings put the team at roughly 90 to 100 people. Sunrise Labs handles development and design transfer and does not run its own volume manufacturing.

Plexus

Plexus Corp. is a NASDAQ-listed company headquartered in Neenah, Wisconsin, that offers design and development, supply chain, new product introduction, manufacturing and sustaining services. Healthcare and life sciences is one of its three markets alongside aerospace and defense and industrial. Its healthcare work includes surgical equipment, imaging equipment and diagnostic instruments. The company has around 20,000 employees in total, though only part of that is healthcare.

Sunrise Labs vs Plexus: pros and cons

Sunrise Labs
+ Deep experience with infusion, fluid handling and other electromechanical systems that most software-led firms avoid
+ Engineers who own mechanics, electronics and firmware sit on the same team, which helps with system-level risk analysis
+ Long track record with US medtech clients and FDA submission support
+ Mid-sized team means senior engineers stay visible on projects
- No in-house volume manufacturing; design transfer to a CM is part of every plan
- US-only footprint and Northeast US rates put it at the higher end on cost
- Less suited to software-only or SaMD projects
Plexus
+ Strong with complex, lower-volume capital equipment such as imaging and surgical systems
+ Offers product engineering as well as manufacturing
+ Sustaining engineering over long product lives
+ Public company with transparent financial reporting
- Generalist manufacturer; healthcare competes with aerospace and industrial for capacity
- Not a fit for early-stage concept work
- Most engineering engagements lead toward a manufacturing contract
