B2B SaaS
A subscription-billed software product sold to businesses (not consumers), typically multi-tenant, with org-level auth, role-based access, and per-seat or usage-based pricing.
B2B SaaS markets sell to companies, often via product-led growth + sales-assisted close. Core features: multi-tenancy (workspace / org isolation at the data layer), SSO (Google Workspace, Okta, Azure AD), role-based access control, audit log, Stripe-billed subscription with metered or seat-based plans, and an admin / billing portal. Typical 2026 stack: Next.js + Postgres + Stripe + Clerk/WorkOS/Auth0.
