How this collection was assembled

Curated researched sample from the 2026-09-19 company inventory; not the full accelerator roster. Membership follows the stated source fields and public descriptions. Where SPC appears, company-directory association is not a Fellowship cohort; where LAUNCH appears, categories are editorial unless the provider exposes them.
