The SaaS story

From single-tenant scripts to AI-ready enterprise platforms

Buyers expect SSO, audit logs, and AI in the same product — we help you get there without pausing roadmap velocity.

“In enterprise SaaS, architecture decisions on day one determine whether you scale to 10 tenants or 10,000 — we build for both.”

How Spectrum delivers B2B SaaS platforms
Act 1

Single-tenant sprawl caps growth

Per-customer deployments, manual onboarding, and bolted-on billing slow sales cycles and inflate infrastructure cost.

Questions

Frequently asked questions

What multi-tenant models do you implement?

Shared-schema with RLS, schema-per-tenant for regulated clients, and hybrid dedicated pods for enterprise logos — chosen based on scale, compliance, and cost targets.

Can you integrate Stripe or Chargebee for billing?

Yes. We implement subscriptions, usage metering, invoicing, plan changes, and webhook-driven entitlements tied to your product feature flags.

How do you build tenant-safe AI and RAG?

We use tenant-scoped namespaces, RLS on Postgres/pgvector, application-layer filters, and tiered model routing so retrieval and inference never cross customer boundaries.

Do you support enterprise SSO (SAML/OIDC)?

Yes. We integrate Okta, Azure AD, Google Workspace, and custom IdPs with role mapping, JIT provisioning, and audit logging.

Can you help migrate from single-tenant to SaaS?

Yes. We plan data migration, tenant provisioning, billing cutover, and phased rollouts with minimal downtime for existing customers.

How do you approach SOC 2 and security?

Secure SDLC, encryption, access controls, logging, and practices aligned with SOC 2 and ISO 27001 — documented for buyer security reviews.

What engagement models do you offer?

Managed dedicated teams, staff augmentation, and fixed-cost delivery for defined MVP or platform milestones.

How quickly can we start?

We respond within one business day. Discovery and architecture workshops typically begin within 48 hours of your consultation request.
