Configuration shouldn't be tribal knowledge.

Once a product has more than a handful of customers, every one of them wants something slightly different — a higher rate limit, an early feature flag, a different SLA, a routing rule that only makes sense for their account. None of that is a bug. It's just what serving real customers looks like.

What actually breaks is where that per-customer configuration ends up living. A row in Postgres here, an entry in a YAML file there, a flag flipped in a dashboard, a value someone SSH'd in and set directly in production at 2 AM because it was faster than filing a ticket. Every one of those places is reasonable on its own. Together, they mean nobody — not the engineer who set it, not the teammate debugging an incident six months later — can answer "what is this tenant's config, actually, right now, and why" without reconstructing it by hand.

We wrote up exactly how that goes wrong in the 2:47 AM story — the incident that's really an amalgam of the incident every team like this eventually has.

What we're building

TenaVault is a single, governed place for that configuration to live: scoped to global, environment, template, and tenant with one enforced resolution order; every write reviewed and sealed before it takes effect; every change permanently recorded, never silently overwritten; and delivered to your application in microseconds through a local-evaluation SDK that keeps working even if we're unreachable. Not a feature-flag tool bolted onto config as an afterthought — a system built around the specific shape of multi-tenant configuration from the start.

Where we are

TenaVault is early and being built in the open with design partners, not a decade-old platform with a polished sales deck. If you're evaluating us, the honest pitch is: the resolution engine, the governance flow, and the delivery SDK are real and working today — and we'd rather show you the actual product on your actual config than promise you a roadmap slide.
