Multi-Tenant SaaS for
Enterprise Scale.

Build a platform that can onboard new tenants in minutes, enforce isolation & data residency, ship upgrade-safe releases, and monetize with metering + entitlements—without rewriting your core product every quarter.

Own your platform primitives and pipelines.

Beyond the “Tenant Toggle.”
Real Multi-Tenancy, Not Hope.

Most SaaS teams hit a wall when growth exposes no isolation model, billing gaps, and unsafe release pipelines. We build the platform primitives so your product can scale without breaking trust—or margins.

The SaaS Failure Pattern

What most “build teams” ship:

  • Isolation by Convention

    Shared tables + weak auth rules cause cross-tenant risk.

  • No Metering Foundation

    Pricing becomes manual, disputed, and margin-leaking.

  • Unsafe Upgrades

    Schema + feature changes break tenants without rollout controls.

The Coretus Platform Standard

Enterprise-grade multi-tenancy:

  • Explicit Tenancy Model

    Tenant context propagation, isolation boundaries, and policy enforcement.

  • Metering + Entitlements

    Usage events, plans, feature gates, and invoice-grade aggregation.

  • Upgrade-Safe Delivery

    Canaries, migrations, compatibility, and tenant-aware release controls.

Isolated Tenants. Predictable Revenue. Safe Releases.
