Subscription software

Multi-tenant products that scale with your customer list.

Tenant isolation, roles, billing, admin and APIs for subscription products from first customer to enterprise deals.

Who it is for

Product companies building or rebuilding a SaaS product.

Usually built with

  • Next.js
  • TypeScript
  • Node.js
  • PostgreSQL
  • Stripe
  • Vercel
  • AWS

Approach

What we have learned building these.

SaaS is where product and business model meet in code. We build the parts first versions forget: proration, seat management, impersonation with audit, data export, and the security answers your first enterprise buyer will ask for.

What matters

The features that decide whether it works.

  • Multi-tenant data model

    Row-level isolation, per-tenant configuration, enterprise-ready from the start.

  • Billing & plans

    Stripe subscriptions, trials, usage-based pricing, dunning.

  • Roles & SSO

    Invitations, permissions, SAML SSO for the enterprise tier.

  • Admin & feature flags

    Support tooling and safe releases.

  • Public API & webhooks

    So customers integrate you into their stack.
