SaaS is a product and an operating model

Building SaaS means more than writing features. You need tenant isolation, subscription billing, onboarding, analytics, uptime and a cost structure that stays healthy as customers grow.

Cruzata brings product engineering experience to each of these decisions, so the platform you launch is ready for paying customers and ready to scale.

  • Multi-tenant architecture
  • Subscription billing and plans
