YOUR PROBLEM

10,000 tests. 4 hours to run. Still miss edge cases.

Regression testing is expensive. Infrastructure costs. Engineering time. Pipeline delays. And after all that expense, tests only prove something worked for the inputs you tested—not all possible inputs.

What if you could prove correctness instead of testing for it?

THE REAL COST OF TESTING

Typical enterprise testing costs (annual):

CI/CD infrastructure $120,000
Test environment maintenance $80,000
Engineering time (test creation/maintenance) $200,000
QA team salaries $300,000
Production bugs (escaped defects) $150,000
Total annual testing cost $850,000

And that's just the direct costs. Doesn't include velocity impact, opportunity cost, or stakeholder frustration.

WHY TESTS FAIL

Sampling problem

Tests check specific inputs. But there are infinite possible inputs. You're sampling. Bugs hide in the untested space.

Maintenance burden

Every code change requires test updates. Tests become brittle. Engineers spend more time fixing tests than writing features.

False confidence

"All tests pass" doesn't mean "the system is correct." It means "the system behaves as expected for the scenarios we tested."

Pipeline bottleneck

Comprehensive test suites take hours to run. Every commit waits. Developers context-switch. Velocity suffers.

THE INSIGHT

What if you could prove correctness instead of test for it?

Tests sample the input space. Proofs cover all possible inputs. Mathematically. Instantly. With no maintenance burden.

The comparison:

Testing

Samples inputs. Hours to run. Requires maintenance. Gives confidence. Misses edge cases.

Proofs

Covers all inputs. Instant. No maintenance. Gives certainty. Catches all edge cases.

SEE IT IN ACTION

proof-vs-tests

Watch a change get verified with proof instead of 10,000 regression tests.

WHAT THIS MEANS FOR YOU

Zero regression testing

Mathematical proof of what's unaffected. No need to test unchanged modules.

100% coverage automatically

Proofs cover all possible inputs. Not samples—complete verification.

No test maintenance

Change the specification, proofs regenerate automatically. No brittle test suites.

Instant CI/CD

Proof generation takes seconds. No 4-hour test suites blocking deploys.
