Our Capabilities
Organisation & Team Management
Multi-level organisational hierarchies — organisations, teams, departments — with member invitations, role assignment and org-level settings management.
Tenant-Scoped Permissions (RBAC)
Role-based access control scoped to each tenant — owners, admins, members with granular resource permissions enforced at the API and database layer.
Custom Domains per Tenant
White-label custom domain support so each tenant can serve your app from their own domain — with automated SSL provisioning via Let's Encrypt.
Tenant Onboarding Automation
Automated provisioning of tenant database schemas, default data seeding, invitation emails, and billing account creation — onboard new customers in seconds.
Data Residency & Compliance
GDPR-compliant data handling, tenant data export and deletion workflows, audit trails, and data residency options for EU/US tenants.
How we work
Fixed milestones, working software every fortnight, and no surprises on the invoice.
- 01
Isolation Model Selection
We evaluate your product's compliance requirements, expected tenant count, performance SLAs and operational complexity to recommend the optimal isolation strategy.
- 02
Database Schema Design
Design of the tenant model, foreign key constraints, Row Level Security policies (Postgres), index strategy, and migration plan for future tenant provisioning.
- 03
Implementation
End-to-end implementation — tenant context middleware, RLS policies, RBAC system, custom domain infrastructure, and tenant admin portal — with comprehensive test coverage.
- 04
Load Testing
Load testing with realistic multi-tenant traffic patterns to verify isolation holds under concurrent load, identify N+1 queries, and validate the provisioning pipeline at scale.

Common questions
If your question is not here, a senior engineer will answer it within one working day.
Ask our teamSchema-per-tenant (separate database schema per customer) provides the strongest isolation, easier per-tenant backups and restores, and is preferred for enterprise/regulated customers. Row-level security (RLS) uses a single schema with a tenant_id column and Postgres policies — simpler operations, lower provisioning overhead, and scales to thousands of tenants more easily. The right choice depends on your compliance requirements and tenant count.
We implement defence in depth: tenant context is set at the start of every request, Postgres Row Level Security policies enforce isolation at the database level even if application code has a bug, all API responses are validated for tenant scope before returning, and we write automated tests specifically designed to probe for cross-tenant data access.
Yes, but it requires careful planning. We conduct a codebase audit to identify all places where data is fetched without tenant scoping, design a migration path that adds tenant context without breaking existing data, and implement the changes incrementally. It's more complex than greenfield multi-tenancy but very achievable with the right approach.
We implement a tenant configuration system — a JSON settings table per tenant that drives feature flags, UI customisation, integration credentials and workflow rules. This avoids custom code per tenant while giving tenants meaningful flexibility. For deeper customisation needs (custom fields, workflows), we build a proper extensibility layer.
With proper indexing on tenant_id columns and RLS policies, the performance overhead of multi-tenancy is minimal — typically under 5% compared to a single-tenant equivalent. The bigger risk is N+1 queries and missing indexes as data grows. We profile and optimise these during load testing, and set up query monitoring in production to catch regressions early.
