Project Images
Good Fit?
Yes:
- • You need a working product, not a team to manage
- • Timeline: weeks to months, not years
- • Small-medium volume (10s to 1000s of units)
Maybe not:
- • You need ongoing staff augmentation
- • High-volume consumer electronics (100k+ units)
- • You already have a full hardware team and just need one specialist
Certification & Compliance
Certification work (CE/FCC/RED/etc) is billed hourly, not included in fixed project price. Lab timelines are unpredictable, and requirements vary significantly by product and market.
