AI writes the code, we prove it works
We analyze your system, generate the properties it should hold, and test them against thousands of scenarios.
Your tests pass, but the code still breaks?
Tests check the cases you thought of. The bugs that cause real incidents — race conditions, missing validations, data leaks — come from the cases you didn't.
Describe what correct means
Write a rule like "balances should never go negative" or "deleted users can't access data." Plain English. Not test code.
We explore thousands of scenarios
We systematically explore the state space of your application so you don’t have to imagine every failure mode yourself.
See exactly what broke
When a rule is violated, you get the exact input, the full execution trace, and a suggested fix. Every finding is reproducible.
The coverage gap
Most tools test a sliver of your system.
We explore all of it.
Reads the changed lines in the PR
Runs the specific cases someone wrote
Systematically tests across your entire system
Beyond just code correctness
Performance Checking
Response time budgets. Throughput ceilings. Memory bounds under load. Define what ‘fast enough’ means for every endpoint, and we’ll tell you exactly which ones don’t meet the bar.
Probabilistic Modeling
We simulate thousands of failure scenarios — node crashes, network partitions, cascading outages — and give you a probability-weighted picture of how your system actually holds up.
For teams where a bug is an incident
Payments & Fintech
Transaction atomicity. Balance consistency across concurrent operations. Currency precision. Idempotent retries. The standards your auditors ask about and your test suite can’t fully cover.
Auth & Identity
Token lifecycle correctness. Permission boundaries across roles. Session state consistency. The invariants that, when broken, become your next security advisory.
Data & Compliance
PII containment. Retention policy enforcement. Access control consistency across code paths. The rules your compliance team defines that your codebase must guarantee.
Infrastructure & APIs
Uptime contracts. Response time bounds. Rate limit enforcement under load. Graceful degradation. The reliability standards your SLAs promise and your customers expect.
Ship faster, break nothing
Give your team the confidence to move fast, and push ambitious changes — knowing that correctness is enforced on every change.
