Tips for Buying Hardware Startups
Prototypes & First Articles Parts

What hardware startups procurement teams should know before ordering prototypes & first articles components.

LA hardware startups launching on Kickstarter should order 5-10 CNC-machined samples before committing to injection molding — you can photograph real machined parts for your campaign page and ship them to early reviewers.

ISO 9001

If you're building consumer electronics in LA, specify a type-II anodize finish on your aluminum enclosure prototypes — it matches the premium feel backers expect and previews your production intent.

UL

For climate-hardware startups at LACI, request salt-spray-tested finishes on outdoor enclosures — LA's coastal moisture accelerates corrosion on untreated aluminum faster than most founders expect.
