Do I need an identity platform for a startup MVP?

Usually no, not at the very beginning—but it depends on what your MVP needs.

You probably don’t need a full identity platform if:

• You’re only supporting a small number of users
• You need basic sign-up / sign-in
• You don’t need enterprise SSO, SCIM, MFA policies, or complex role management
• You want to move fast and validate product-market fit

In that case, use a managed auth provider like:

• Clerk
• Auth0
• Firebase Auth
• Supabase Auth
• AWS Cognito
  These give you login, password reset, social login, and basic user management without building everything yourself.

You might need an identity platform sooner if:

• You’re selling to enterprises
• You need SSO/SAML/OIDC
• You need multi-tenant orgs, RBAC, or delegated admin
• You need compliance/audit trails
• Identity is part of the product itself
• You expect complex authorization rules across apps/services

Practical rule of thumb

For most startup MVPs:

1. Use a hosted auth provider
2. Keep your auth/authorization simple
3. Don’t overbuild “identity” until customers demand it

A good MVP approach

• Start with email/password or Google login
• Add organization accounts only if needed
• Use simple roles like owner, admin, member
• Store authorization rules in your app, not in a custom IAM system

If you want, I can also give you a decision tree for when to use:

• simple auth,
• auth + roles,
• or a full identity platform.
