A developmental platform for the agents you've already shipped.
Most AI agents live somewhere between the demo that wowed you and the outage that scared you. The gap is rarely capability — it's reliability under real conditions. Agent Etna closes it without asking you to start over.
What Agent Etna is
A platform you point at the agent you already run. Etna profiles what it does, generates realistic scenarios that probe how it behaves, scores each one with an independent judge, and proposes small, targeted improvements. You decide which ones ship.
Everything happens against a private, throwaway copy of your agent — never the live one. Each proposed change is validated against held-out scenarios and a safety battery before it can graduate from the sandbox. Nothing reaches production without your explicit approval.
Who it's for
Builders who have shipped an agent and now need it to behave more reliably, more faithfully, and more cheaply over time. We work with:
- First-time builders shipping their first production agent and looking for a safety net.
- Experienced creators running a mature agent who want to compound small wins instead of triaging incidents.
- Enterprise teams who need every change to be auditable, gated, and reversible.
The principles we build by
Safety is the default, not an afterthought.
Every test runs against a private sandbox. Your live agent, its users, and its data are never touched. The worst case for a failed cycle is exactly nothing.
Honest judgment, not a rubber stamp.
Changes are graded by something independent of the agent itself, against what the agent is actually meant to do (the calibration you confirm before cycle one). A change only ships if it made the agent genuinely better — it can't slip through by gaming a score or quietly weakening a safeguard.
Improvement that compounds.
Each cycle prioritises what the previous one left weakest, so progress accrues instead of plateauing. Held-out scenarios catch metric-gaming. The history of every change is recorded in your own repository — yours to keep.
You always have the off-switch.
Nothing goes live without your approval. If a deployed change ever misbehaves, it rolls back on its own. You can disconnect at any time, and the record of what we did stays in your repo even if you stop using us.
How we're different
We don't retrain your model — we don't need to. Agent Etna treats your agent as the artefact it is (code, prompts, tools, fallbacks) and improves the scaffolding around it through small, auditable changes you choose to ship. That's why the worst case is nothing, and the best case is an agent that quietly gets better while you sleep.
