Verification for AI-built software

Your agents ship fast.Do they ship correct?

Running coding agents in parallel is native now. Trusting what they produce is the part the tooling doesn’t solve. Plumbline is the verification layer that keeps them honest.

43 green tests. One broken ship.

Every test asserted against a mock. None of them ran the code. It shipped broken anyway — and no dashboard ever showed it. That quiet gap is exactly what we measure.

The Drift Audit

One week. Fixed fee. Zero access to your systems.

A teardown of your agentic build that tells you exactly where you’re exposed — and how to fix it. The whole engagement runs through a relay you control. We never touch your infrastructure or your data.

PROOF

Real proof vs. green checkmarks

Do your tests execute the code, or just assert against mocks?

DRIFT

Intended vs. committed

Does what your agents committed actually match what you meant to build?

STATE

State & handoff integrity

Can a fresh session reconstruct the truth, or is it locked in one person’s head?

GATES

Dangerous-change gates

Where can an agent touch sensitive code or data with no human in the loop?

BLOCK

The one blocking gate

Is there a single mechanical check that stops a bad change before it ships?

LANES

Lane isolation

Are your parallel agents truly isolated, or quietly clobbering each other?

Why Plumbline

Built by someone who couldn’t afford to ship wrong.

Plumbline’s method comes from running a HIPAA-grade, verification-first agent build system — a no-shell architect that physically can’t fudge state, live-execution proof on anything that touches data, and a human gate on every dangerous change. We understand high-trust stakes from the inside, not from a checklist. And because we never hold your systems or data, the rigor is built into how we work, not bolted on.

Can you prove your agents are shipping correct code?

If not, that’s worth fixing before it costs you.
