CSA STAR Registry

Karsenics PBC is a Texas public benefit corporation based in Houston. We build and run Karsenics OS (KOS), a registration and event operations platform for Pride organizations, festivals, parades and other community nonprofits.

KOS handles vendor, exhibitor, food, parade, sponsor and volunteer registration, along with payments, signed documents, booth maps, parade lineup and day-of check-in.

Each client organization gets its own isolated KOS site and database. No client's data is shared with another client. Payments go through Stripe Checkout straight to each organization's own Stripe account, so KOS never sees or stores card data. KOS is hosted on Render.

This STAR entry covers KOS, the client-facing platform.
