AI reliability · evals · pressure-testing

Your AI works in the demo. Are you sure it won't go rogue in front of a customer?

I pressure-test AI products like a demanding real user, find where they break, and build the evals that catch it — so it doesn't happen in front of the people who matter.

refund

A dealership bot was talked into selling a car for $1 — and agreeing it was legally binding.

legal

An airline was held liable when its chatbot invented a refund policy that didn't exist.

brand

A delivery company's bot was prompted into writing poetry about how much it hated the company.

What I do

Find where it breaks. Then keep it from breaking again.

Three things, in the order that actually protects you — catch the failures now, then put guardrails in place so they don't come back on the next release.

01

Pressure-test

I use your AI product hard, like a demanding real user, and hand you a report of everywhere it produces wrong, inconsistent, or embarrassing output — before your customers find it.

02

Build your evals

I set up the evals that keep your AI on the rails — so every prompt change and model swap gets checked automatically instead of quietly breaking in production.

03

Review & improve

Already have evals? I review what you've got, find the gaps and blind spots, and tell you exactly where your coverage is thinner than you think.

Who's behind this

You need someone who's actually shipped this — not someone reading about it.

I'm Justin. I've spent years shipping real AI products — LLM features, RAG systems, and 0→1 platforms taken to enterprise scale — which means I know the specific, unglamorous ways they fail in the wild.

AI generates the options. The hard part is judgment: knowing what "good enough" means for your product, and spotting the failure a generic automated check waves right through. That's pattern recognition built from years of doing it — not theory, and not something you can fully hand to another model.

Before this I worked across Google, Two Sigma, and Oliver Wyman — building data and analytics products and learning how the best organizations make product decisions.

Common questions

The short answers.

Is this security red-teaming?

No. I'm not testing whether hackers can break in — I'm testing whether your AI produces bad, wrong, or embarrassing output for ordinary users doing ordinary things. It's product quality and reliability from the user's side of the screen, not cybersecurity.

Why is it so cheap?

Introductory pricing for the first few clients. The price goes up once those founding spots are filled. Lock it in now.

What stage should my startup be?

Early stage — pre-seed through Series A — building an AI product, moving fast, and nervous about what it might do in front of real customers.

Will AI just do this itself?

AI can help run the tests, but it can't be the final judge of its own output — it shares the same blind spots as the model you're checking. Deciding what counts as a failure, and catching the subtle ones, still takes a human with product judgment. That's the part you're paying for.

What if I want to cancel?

Cancel anytime. No contracts, no minimum, no awkward conversation. Just email and you're done.

Stop hoping it behaves. Start knowing it does.

A few founding client spots at $1,000/month. When they're gone, the price goes up.
