Multi-tenant SaaS
built for growing demand

We design SaaS platforms where each customer's data stays separate and in the right region, new customers can be set up quickly, upgrades roll out safely and usage is billed accurately, without rewriting your core product.

What's included

What we
build for you

6 capabilities, delivered by one squad. Use what you need now and add more as you grow.

  • 01

    Tenancy architecture

    Choose how tenants share infrastructure, from shared tables to separate databases or cells, and route each request to the right place.

    • Row, schema or database isolation
    • Tenant context propagation
  • 02

    Identity and RBAC

    SSO, roles, permissions and tenant admin controls, with access that is easy to audit.

    • SAML and OIDC
    • Fine-grained permissions
  • 03

    Metering and billing

    Usage events, plans, entitlements and invoices, with totals you can check line by line if a customer questions a bill.

    • Usage events
    • Entitlements and plans
  • 04

    Provisioning and lifecycle

    Self-serve sign-up from tenant templates, plus controlled upgrades and offboarding when a customer leaves.

    • Automated onboarding
    • Tenant templates
  • 05

    Monitoring

    Metrics, logs, traces and SLOs broken down by tenant, so you can see who is affected and what each customer costs to serve.

    • Tenant SLOs
    • Cost and usage dashboards
  • 06

    Security and governance

    Activity records, data kept in the right region, encryption boundaries and least-privilege access.

    • Activity records
    • Data residency controls

Our approach

What usually goes wrong,
and what we do instead

  1. The usual way

    Shared tables and weak access rules that risk one tenant seeing another's data.

    How we do it

    A clear tenancy model: every request carries the tenant's ID, and policies block access to any other tenant's data.

  2. The usual way

    Usage isn't measured, so invoices are built by hand, customers dispute them and revenue slips through.

    How we do it

    We record usage events, total them per customer and tie them to plans and feature limits, accurately enough to invoice from.

  3. The usual way

    A schema or feature change goes to every customer at once and breaks some of them.

    How we do it

    Changes reach a few tenants first, with safe database migrations and compatibility checks before the wider rollout.

Architecture

How it's
put together

Each layer has a clear job, so the system is easier to secure, test and extend.

  1. Layer 01

    Control plane

    The part of the platform that creates, configures and retires tenants, and holds the policies and admin tools.

    • Provisioning
    • Policies
    • Tenant templates
  2. Layer 02

    Data plane

    The APIs and storage your customers use every day, with isolation on every request and partitioning for scale.

    • Isolation
    • Caching
    • Partitioning
  3. Layer 03

    Identity and access

    SSO, RBAC, tenant admins and activity records for business customers.

    • SAML
    • OIDC
    • RBAC
    • Audit logs
  4. Layer 04

    Billing and monitoring

    Usage events rolled up into invoices, plus SLOs and costs tracked per tenant.

    • Usage events
    • Invoices
    • SLOs
    • Cost attribution

How we deliver

From first review
to live in production

4 phases, each ending with an output you can review.

  1. Step 1: Platform audit and tenancy blueprint

    We review your current platform, choose the tenancy model and plan how to get there from where you are today.

    Output: Multi-tenant architecture blueprint

  2. Step 2: Identity and access foundation

    We add SSO, roles, tenant admin controls, audit logs and policy checks.

    Output: Sign-in ready for business customers

  3. Step 3: Metering and entitlements

    We capture usage events, total them, enforce plans and build reporting accurate enough to invoice from.

    Output: Billing core

  4. Step 4: Release safety and monitoring

    We add staged rollouts, safe migrations, compatibility checks, per-tenant dashboards and cost tracking.

    Output: Upgrade-safe platform

Trust and control

Safe by design,
not by policy alone

There are three common models: shared tables with row-level isolation, a schema per tenant, or a database per tenant. Shared tables cost least to run, while separate databases give the strongest isolation. We compare them against your compliance needs, customer size and growth plans, and some platforms mix models for different customer tiers.
