Déjà exists to prove exactly how failure was resolved.
We replace tribal knowledge with a cryptographic chain of custody. No guessing. No recurrence.
Most production incidents aren't new problems. They're old problems wearing new clothes. An engineer spends hours diagnosing an issue that was already fixed months ago — but the fix is buried in logs, pull requests, threads, or the memory of someone who's no longer there.
Incident tools document what happened. Ticketing systems track what people said. Déjà remembers what actually worked.
What Déjà is
Déjà is an institutional memory system for production incidents. It quietly learns from resolved failures, links them to the code that fixed them, and recalls those fixes when the same incident returns.
What Déjà is not
Déjà is not a 'Co-Pilot.' It does not guess. It is a System of Record for remediation. While other tools suggest what might be wrong, Déjà records what actually fixed it.
Déjà only speaks when it has something proven to say.
- Trust is earned through restraint. In an era of probabilistic AI, we choose deterministic math. We believe incident resolution requires proof, not prediction. If we can't mathematically verify the fix, we stay silent.
- Memory compounds over time
- Proven fixes beat speculation
- Context matters more than noise
- Infrastructure should feel calm
Do you believe that tools should be quiet until they have something proven to say?
See how we build at DéjàScale-ups die from regression, not stagnation. Déjà ensures that as you ship faster, your 'Known Error' database grows automatically. We turn your outage history into an automated regression suite.
Over time, Déjà becomes the quiet layer that outlives deploys, refactors, reorganizations, and turnover.
When production breaks, recall the last proven fix — in seconds.
Build memory that survives change.
Engineers leave. Context is lost. Code is rewritten.
Déjà ensures the solution stays, even when the author goes.
