Fractional CTO · B2B SaaS
Fractional CTO for B2B SaaS founders
From first paying team to enterprise readiness without rebuilding the foundation.
The case
B2B SaaS engineering is not generic engineering.
Most B2B SaaS products die in the gap between 'self-serve startups love it' and 'enterprise teams will pay for it.' That gap is engineering: SSO, audit logs, role-based access, sandbox environments, API rate limits, and the dozen other things every procurement team asks about. We help B2B SaaS founders build the right architecture early so enterprise readiness is a quarter of work, not a rewrite.
B2B SaaS architecture decisions compound. A fractional CTO with SaaS battle scars makes the high-leverage calls — multi-tenancy, RBAC, public API design — and stays on long enough to ensure they survive contact with your first 10 customers.

FAQ
B2B SaaS questions founders ask
How do you decide between shared-schema and schema-per-tenant? +
Shared schema with tenant_id columns wins for 9 out of 10 B2B SaaS products. Schema-per-tenant only when you have compliance or noisy-neighbor reasons that force it — and we make sure those reasons are real, not hypothetical.
When should we add SSO? +
When your first prospect with a $20k+ annual contract asks for it. Build it on WorkOS or Auth0 rather than custom — they handle the protocol edge cases (SAML, OIDC, SCIM provisioning) that will eat months otherwise.
How do you handle usage-based pricing? +
Stripe Metered Billing or Orb for the billing engine, with usage events written to a separate ledger you control. Never derive the billing total live from your application database — you need a separate, immutable, queryable usage record for disputes and audits.
