Our regulator requires our data to stay in the EU. Yours is in Tokyo. Isn't this conversation over?

The question a Chief Enterprise Architect (CEA) asks.

The short answer

Today: Tokyo only — I won't pretend otherwise. But the EU cell is built in configuration, provisioning is weeks of work, and we will make it a contractual condition of your go-live.

The full executive answer

It is not over, but I owe you complete precision, because this is a compliance question and vagueness here would be disqualifying. Current state: the production data cell is Supabase Postgres in Tokyo — a single region. If your regulatory position requires EU-resident data at rest from day one, we cannot satisfy that with today's provisioned infrastructure, full stop.

What makes this a milestone rather than a dead end: the platform was architected cell-based from the start. An EU cell — and an India cell — already exist as configuration in the codebase; the region registry, the routing, and the per-cell heartbeat monitoring are built. What is missing is the provisioning act itself: standing up the EU Supabase project and switching the configuration live. That is infrastructure work measured in weeks, not an architecture programme measured in years — and precisely because it is provisioning, we can tie it contractually to your go-live as a condition precedent, with your deployment landing in the EU cell on day one and never touching Tokyo.

Two flanks I will name before your DPO does: first, AI processing — model calls go to Anthropic and OpenAI, so the data-processing agreement chain and transfer mechanism for those subprocessors must be part of the same review; PII is redacted from text before it reaches any model, which narrows but does not eliminate that analysis. Second, we run this as a GDPR Chapter V transfer question with your privacy team at the table, not as a sales workaround. Honest gap, engineered path, contractual commitment — that is the offer.

Grounded in: GDPR Chapter V (international transfers); data-residency requirements in EU DORA/EBA regimes
