What You're Up Against

The Bill for Architecture Shortcomings Comes Due at Customer Twenty

It rarely looks like a crisis. One customer wants configuration modified for their workflow, so you fork the manifest. Another wants their data to reside in a different region, so you fork the stack.

A third one needs SSO against their IDP, and now you have 3 auth paths. Two years later you have 20 deployments under the same brand, and every new feature is delivered as 20 variants.

Common Failure Points

Where It Usually Breaks

Tenancy

Data isolation is implemented in application code not in the data layer, and a misplaced WHERE clause turns into a cross-tenant information disclosure.

Identity

Every enterprise customer expects to use their own identity providers. The initial implementation was designed for a single provider.

Entitlements

Plans, feature gates and RBAC are scattered across the code base, and no one knows what a customer is entitled to beyond inspecting the source code.

Metering

Usage is tracked for billing purposes, but not for cost analysis. You know how much a customer pays, but not how much they cost.

Onboarding

A fresh install always requires an engineer to bring up a new tenant, slowing down customer acquisition.

Operations

There is no per-tenant observability, so “all customers are reporting slow performance” is indistinguishable from “one customer is reporting slow performance”.

What We Code

What We Deliver As Part Of A SaaS Platform

Tenant Architecture

An intentional choice between shared schema, schema-per-tenant, or database-per-tenant based on your compliance requirements and cost envelope, not on defaults or developer convenience. Isolation is enforced at the data layer so it remains intact as your code base evolves

Identity Access Management

SAML and OIDC-based SSO into customers' identity providers, plus SCIM provisioning for user lifecycle management in their target systems. RBAC and ABAC guardrails with full audit logging of who viewed or modified what data

Entitlements, Billing, Usage

A single source of truth about plans, limits, and feature access entitlements. Integration with Stripe, Chargebee, Paddle, or your existing billing stack. Pricing models expressed in code accommodate any combination of usage-based, seat-based, or other metrics with proration and mid-cycle upgrades handled correctly.

Metering and Unit Economics

Per-tenant instrumentation of usage metrics and infrastructure costs. Gross margins per customer, not just revenue, are visible at all times.

Admin and Internal Tools

The consoles for your support and customer success teams to administer tenant-specific settings, impersonate users, modify quotas, toggle features, and export data are prioritized. They comprise the most-used surfaces in your platform.

Integration Surface

REST APIs, webhooks, and connections to the ERPs, CRMs, project management tools, and other systems your enterprise customers want to integrate with. APIs are versioned, documented, and rate limited.

Operations

Per-tenant dashboards and alerting, blue-green canary deployments, zero-downtime migrations across thousands of tenants, and runbooks for the incidents that inevitably occur.

Engagement types

Where We Usually Come In

New Platform Build

You have a commercial opportunity and need to build the platform right the first time. Typical path: discovery, architecture, and development sprints to get to a launch with your first set of production customers. Usually takes 4-9 months after architecture sign-off.

Platform Modernization

You have customers, cash, and a huge technology debt as your single-tenant architecture begins to prevent you from getting new customers. We can help you to iteratively upgrade your production environment to a multi-tenant architecture.

Enterprise Readiness Race

You are losing sales because of an unfulfilled security architecture or the lack of SCIM/Audit Logging/RBAC. Guided communication helps you identify your most pressing platform deficiencies, including a penetration test, SOC 2 preparation, etc.

System-Based or Private-Branded Software as a Service (SaaS)

It's about turning an internal service/suite-of-services into a product. We can deliver multi-tenant, brand-specific SaaS to you with the appropriate tools for you to deliver it to your customers.

Dedicated Platform Team

It's about a dedicated team that works with your product team to design and deliver the platform.

Process

How the Interaction Platform Works

Discovery · 1-2 weeks

We read the code, understand data flows and integrations, interview the support teams who handle day-to-day incidents.

What you get: Written architecture assessment with risk prioritization.

Target Architecture · 2-3 weeks

We produce reference architectures for tenants, identities, integration processes, deployment concepts, costs for 3 stages of scale, and migration sequence – in other words, what your steering committee will actually review and approve.

Foundation · 4-8 weeks

Tenants, identities, permissions, and the deployment process; nothing customer-facing gets delivered before the foundational set of features is completed and thoroughly tested because additional isolation is a platform responsibility.

Feature Delivery

Capacity, deployment, and scale reviews every 2 weeks; your team actually reviews working software rather than design documentation.

Assurance

Peak load testing, chaos engineering, third-party penetration testing, and documentation.

Operation or Delivery

Your choice: Engineering management with an SLA or knowledge transfer/documentation to make you fully self-sufficient in managing and operating the platform.

FAQ

Frequently asked questions

It depends on your compliance requirements, where your largest clients' data resides, and your pricing model. A shared schema with class-level security is the cheapest but potentially the most error-prone; a per-client database schema is the easiest to audit but has the highest cost per client. Enterprise platforms typically use a hybrid approach, with the option to have a dedicated schema on request but shared by default. We'd establish the balance during the discovery phase.

Usually, yes; we can start with a mechanical process of separating the tenant, identity, and permission databases and subsequently migrate workloads to the new shared platform. This is a slower process than paper design suggests, but in practice, no one actually rewrites enterprise systems from scratch.

We design and implement the technical controls necessary for SOC 2, but we are not a SOC 2 audit firm. We collaborate with your auditor to ensure that everything is implemented correctly, but we cannot provide SOC 2 audit or attestation services.

You do. We deliver a working software product to you; our tools and documentation don't include anything proprietary. Have the necessary knowledge about your platform to optimize your next development cycle. Let us take a look at your platform, system architecture, and interface specifications for 2 weeks – and we'll show you what we've found.
