Where it hurts
Tenant isolation drift
A migration here, a feature flag there; one quarter later tenants leak.
How we solve it
Schema-level and row-level tenant boundary
Dual-layer isolation with automated drift checks on every migration.
- GDPR
- KVKK
Industry
SaaS that scales without losing its soul
Multi-tenant, usage-metered, and billing-ready from day one, with a clean upgrade path as you grow. Tenant isolation is checked on every migration, and compliance evidence collects itself in the background.
Compliant by design

Where it hurts
Each card pairs a pain with the capability we ship for it.
Where it hurts
Usage metering edge cases
Retries, refunds, plan switches and the invoice that nobody can explain.
How we solve it
Idempotent event meter with replays
Every usage event is keyed, replayable and reconcilable against billing.
- GDPR
- KVKK
Where it hurts
Billing and engineering coupling
Pricing changes need a sprint; promotions need a release; experiments stall.
How we solve it
Decoupled billing engine and product catalog
Pricing, promotions and plan changes ship without a code release.
- GDPR
- KVKK
Where it hurts
Compliance evidence drag
Every audit cycle pulls senior engineers off the roadmap for weeks.
How we solve it
Continuous controls and auto-evidence
Drata or Vanta hooks log evidence as work happens, not at audit time.

How an engagement runs
From first call to a working demo in two weeks, then weekly releases.
- 01Week 1
Map the tenancy model
We review your data model, isolation boundaries, and billing rules, and write down where they drift.
- 02Week 2
Demo on your model
A working isolation and metering slice on a copy of your schema, with drift checks running in CI.
- 03Weekly releases
Build and integrate
The billing engine decouples from the codebase; pricing and plan changes move to the catalog.
- 04Ongoing
Run and improve
Monitoring, evidence collection, and an upgrade path that stays clean as tenants multiply.
