Find Your System's Rarest Bugs
For software that coordinates many servers, the worst bugs only appear in rare timing situations. We build a simulator that tries enormous numbers of them and replays any failure exactly.
- Pilot the plan to start small
- Inspected before it goes live
- Monthly or every 3 months, or yearly
- 2–4 days build time, once your material is in
What you get
- Injectable time, randomness and I/O in your core
- Deterministic simulator with fault injection
- Checkers for your correctness rules
- AI failure grouping and case shrinking
- Seeded CI runs plus long nightly runs
- Exact replay from seed for every failure
How your order runs, after you choose a plan
Questionnaire
You answer a short questionnaire about your business, your goals and your style.
Five sample concepts
We prepare five sample directions built from your answers — designs, personalities, layouts or setups, depending on the service.
You choose or mix
Pick one, or mix them — for example the colours of one with the layout of another.
Upload your material
Send your logo, photos, prices and texts. We use only what you give us.
We build it
Our specialist AI team builds the complete service from your choice and your material.
Quality inspector
An automated inspector checks the work. Anything that fails is rebuilt before you see it.
Live
A website goes live on your own domain; everything else arrives in your dashboard.
The five samples usually arrive within minutes. Each service's build time is counted from the day your questionnaire and material are complete.
How it works
What it does for you, every day, once it is live.
- 1Runs nightly simulations and groups failures by cause
- 2Shrinks each failure to the shortest replayable case
- 3Explains invariant violations in plain words
- 4Suggests new fault scenarios from recent code changes

- Built on your business — your data, rules and tools — by our specialist AI team, not a generic template.
- Every delivery passes our quality checks before you see it: tested, working and documented.
- On a monthly plan, the AI usage is included up to your allowance, so your bill is predictable. Beyond it you pay only the rate shown, or move up a size.
- On every plan: we keep it live and running, improve it each month from its own results, and your monthly care rounds cover changes, fixes and help.
Included in the price
- The service built for your business and running (or delivered)
- Your workflows running on our machines

What we need from you
We use only what you give us — we never invent your details.
- Which language is the system written in?
- What correctness rules must always hold?
- Which failures have you seen in production?
- Where can long nightly runs execute?
Your data stays yours.
The promise, in plain words — and each part is built into how we work, not just written here.
Encrypted, per customer
Everything you send us is encrypted with keys that belong to your account alone.
Used only for your service
Your files and answers are used to build your service — never for another customer's work.
No outside AI without approval
Data you mark confidential is not sent to any outside AI service we have not approved. By default it is handled only by our own tools.
Delete everything, any time
From your account you can delete everything you sent us and everything built from it. Your keys are destroyed, so even backups become unreadable, and you get a deletion receipt. Only the invoice records that accounting law requires are kept.
Add-ons & upgrades
Start with the build, then add what you need — anytime.
