Transforming B2B SaaS through Technology
Moving upmarket requires enterprise features you cannot retrofit: proper multi-tenancy, SAML SSO, SCIM provisioning, audit logging, and usage-based billing. We build them in from the start or add them without breaking what exists.
Multi-Tenancy Done Right
Multi-tenancy is the most consequential architecture decision in B2B SaaS. Row-level isolation is cheapest but hardest to secure. Schema-level is safer but costlier to manage. Database-level is most isolated but most expensive. We help you choose correctly.
Data isolation failures end companies. One customer seeing another customer's data triggers breach notifications, contract terminations, and reputational damage. We implement isolation at the query layer with automated testing that verifies boundaries continuously.
Tenant-aware operations (migrations, feature flags, billing) require tooling that most teams build ad-hoc and break regularly. We implement tenant management as a first-class system concern from the start.
The largest tenants will demand dedicated infrastructure. Your architecture needs to support both shared-pool tenants and isolated enterprise deployments without maintaining two separate codebases.
Enterprise Features That Close Deals
Enterprise procurement has a checklist. SAML SSO, SCIM provisioning, audit logs, RBAC, and data residency options. Missing any one of these can block a six-figure deal for months. We build them all.
SSO implementation seems simple until you handle: IdP-initiated login, just-in-time provisioning, group-to-role mapping, and the edge cases where Okta, Azure AD, and OneLogin each behave differently.
Usage-based billing requires accurate metering, invoice generation, and the grace periods and notifications that prevent enterprise customers from being surprised. We integrate with Stripe, Chargebee, or build custom.
Enterprise audit requirements mean every data change must be traceable: who changed what, when, from where, and why. Our immutable event log captures this without degrading application performance.
