How do I find a co-packer that accepts small startup runs?

Look for contract beverage manufacturers with emerging-brand programs, mobile canning operators, and shared commercial kitchens. Vetting them for FDA registration, GMP, and liability coverage is the slow part. The AJ Cosmo Labs iPhone app lets you browse vetted co-packers by category and minimum, message them directly, and request quotes, cutting weeks of cold outreach down to a few days.
