You've read a hundred résumés this week.
Every one of them asked you to believe it.
To take a number on faith.
To trust a list of skills.
You couldn't verify a single one.
I'm Matt Nardizzi.
I keep enterprise customers — and I built the AI product they rely on.

The person who keeps the customer — and can build the product. There aren't many of us.
For twelve years I've been the one enterprises trust: the relationship that survives the renewal, the account that grows instead of churns. Then I taught myself to build, and shipped the actual product. I work where the customer relationship meets engineering — I can hear what a client truly needs, show them, fix it, and make sure they stay.

The record
Hand me the accounts you can't afford to lose. I grow them.
Twelve years owning enterprise relationships — onboarding, retention, expansion, and the executive QBRs that keep a renewal from ever being in question. Six companies, one pattern: trusted with the accounts no one could afford to lose, and they grew.

What I built
Then I built the kind of product enterprises have to trust.
Tex is a live AI product I architected and shipped solo. It finds the AI agents already running inside a company's Microsoft directory, decides what each one may do — permit, forbid, or hold — and signs every decision with a receipt the customer can verify themselves. Python engine to React interface. It's live.

The proof
Don't take my word for it. Take the receipt.
I built Tex on one doctrine: never ask to be trusted when you can let someone verify. Here it is, made literal. Type anything — your browser seals it into a SHA-256 hash, the same primitive Tex signs with, computed on your machine and sent nowhere.
Computed in your browser with the Web Crypto API — nothing leaves this page. Change one character and the entire seal changes. That's the difference between a claim and a proof.

What's next
I want the seat where keeping the customer and knowing the product are the same job.
Enterprise account management. Strategic customer success. The technical-account or enterprise-AE seat at an AI company — where someone has to own the relationships that decide the renewal and actually understand what they're serving. If that's the seat you're filling, we should talk.

Proof, not promises.
Let's build something worth keeping.
Boston, MA — and ready to relocate. The fastest way to know if I'm real is to watch the demo.
