Stripe Connect, batteries included.
Payments infrastructure for GitHat-platform apps — Stripe Connect Express, next-day payouts, marketplace splits, Stripe Tax.
Sebastn is the payments-as-a-service layer for the GitHat platform. We own the Stripe Connect platform acct_1QUAtoP61QTCwfMg and onboard apps as connected accounts — so they get Stripe Connect Express with one integration, every payment method.
- Connect Express onboarding in < 5 minutes
- Marketplace splits with application_fee_amount
- Next-day payouts on the platform's schedule
- Stripe Tax automatic tax calculation in 40+ jurisdictions
- Identity verification via Stripe Identity
- Refunds + disputes dashboard
- ClickReserv — booking platform, businesses are Stripe connected accounts under Sebastn
- Quantl — subscriptions for paid tiers
- Any GitHat-platform app that needs payments without re-implementing Stripe Connect
Sebastn auth is delegated to GitHat (api.githat.io). All operator login, MFA, OAuth, passkeys, and audit log live there — Sebastn never holds its own auth surface.
