NEMESIS, by HiveMind AI
Find the weak spots before an outage does.
NEMESIS is an adversarial reliability tester. You point it at a system; it safely and reversibly breaks things, then hands you a ranked map of where the system is weak — and the cheapest order to fix it.
Every system has blind spots: the dependency that takes everything down with it, the retry that turns a hiccup into a pile-up, the restart that quietly loses data. You usually learn where they are during the outage. NEMESIS finds them first, on purpose, under control.
What it is
A stress test that thinks like failure.
Most testing checks that a system does the right thing when everything goes right. NEMESIS does the opposite. It attacks a system the way real trouble does — a service that slows to a crawl, a dependency that drops, a job that is killed halfway, a disk that fills — and watches what breaks, what recovers, and what quietly does the wrong thing.
The point is not to collect a pile of failures. The point is the map it draws from them: where you are weakest, which failures share one root cause, and what to fix first for the biggest gain in reliability.
Entropy keeps order
Our operator product watches a running system and repairs the common breakages by itself. It keeps disorder out.
NEMESIS finds the cracks
Its counterweight lets disorder in on purpose, under control, so you learn where a system would break before it does.
How it works
Prove the undo. Then break, rank, and plan.
NEMESIS works in one disciplined loop. Safety comes first: nothing touches the real system until its reversal is proven. Then it finds the weak spots, ranks them, and turns the whole pile into a single repair plan.

Find — break things, safely.
NEMESIS runs a battery of controlled attacks against the system. Each one is reversible: it proves the undo on a copy first, runs the attack, watches how the system responds, then puts everything back the way it found it.

Rank — turn failures into a map.
A long list of failures is noise. NEMESIS removes the duplicates, groups the failures that trace back to the same root cause, and ranks what it finds by how much it would hurt and how easily it is triggered. You get weak spots, not a log dump.

Fix plan — the cheapest order to fix.
It hands back a prioritised repair plan: the highest-payoff weak spot first, down to the ones that can wait. This is the triage a senior engineer would do by hand — done for you, and ready to hand to whoever does the work.

1
Highest payoff
One dependency takes everything down with it
When a single downstream service stalls, requests pile up until the whole system is unresponsive.

High
A restart mid-job loses work silently
Interrupting a task leaves no error and no record — the work simply disappears.

Can wait
Recovery is slow after a dependency returns
The system comes back, but takes far longer than it should to catch up once the dependency is healthy again.
Who it is for
For any team that cannot afford to find out the hard way.
If you run real infrastructure or services, you already know some of your blind spots — and you lie awake about the ones you do not. NEMESIS is for the teams who would rather meet those blind spots in a controlled test than at 3 a.m.
Production services and APIs
Anything customers depend on staying up. Learn what a slow dependency or a bad deploy actually does to you, on your terms.
Data pipelines and scheduled jobs
Work that has to run on time and finish clean. Find the jobs that lose data or jam the queue when something upstream hiccups.
AI agents and automations
Systems that act on their own. See how they behave when a tool times out, a call fails, or the input is not what they expected.
Platform and reliability teams
The people on the hook for uptime. Get a ranked, de-duplicated list of what to harden first, instead of a backlog of hunches.
Hard limits
What NEMESIS will not do.
Leave damage it cannot undo
Every attack proves its reversal on a copy before it runs. An attack whose undo does not hold is never run against the real system.
Go beyond the scope you set
It attacks only what you point it at, inside the limits you set. It does not wander off into systems you did not name.
Hide what it did
Every attack, every result, and every step of the undo is written down. You can read the whole run back, start to finish.
