How is an AI product lab different from an AI agency?

A lab ships its own products. Vesti Labs runs Interface Audit, Dreszi, and Pulso, so the method sold to clients was used first on products the lab owns, by the same people who do the client work.

We build AI products. Ours ship first.

Q: What does Vesti Labs build?

AI applications for web and iOS, agents and internal tools wired into a company's systems, custom models with their evaluations, and the interface and launch work around them.

Q: How does an engagement start?

With a first read at no cost, then a fixed-scope, fixed-price executive brief that diagnoses the problem and lays out the build.

Q: Where is Vesti Labs?

Austin, Texas. The lab works with teams across the United States and Latin America, in English and Spanish.

Vesti Labs is an applied AI lab in Austin. We design, engineer, and launch AI apps, agents, and custom models. Every method we sell was used first on a product we own.

Illustrative runs. Figures in the simulator are examples of the method, not client results.

001 ThesisAI products die in the handoff.

Most companies hire a strategy firm, then an agency, then a dev shop. Each one hands the next a document, and the context stays behind. An AI product is mostly context: the data, the edge cases, and the reason a model should answer one way and not another.

Strategy. Design. Engineering. Three industries built to answer questions. None built to ask better ones.We ask the questions before the questions are asked.Decisions and code, made by the same tailored intelligence.

MIT Project NANDA, The GenAI Divide: State of AI in Business 2025. Deployment shares are approximate and self-reported, and the authors say they do not show that partnering causes success.

002 VitrineProducts we ship

We run three products of our own. Each one tested part of the method before any client paid for it.

Part	Product	Platform	Status	What it does
VL-01	Interface Audit	Web	Live	Audits a website against 168 peer-reviewed UX principles in about 30 seconds.	interfaceaudit.com
VL-02	Dreszi	iOS	In launch	Wardrobe intelligence. One outfit each morning, already right.	dresz.io
VL-03	Pulso	Partner app	Closed	Signal detection for regulated prediction markets. Its Bayesian thesis became Chevalière.	Case notes coming

Interface Audit

UX insights agencies charge thousands for. 2,098 citations. Zero opinions. Paste a URL and the audit returns findings with the research behind each one.

003 AtelierWhat we build for you

Client work runs on the same tools as our own products. Every line below has already shipped once.

Capability	What you get	Shipped first in
AI apps	Web and iOS products with a model at the core, from prototype to store release.	Dreszi
Agents and internal tools	Agents connected to your systems, data, and approvals, with an off switch your team controls.	Pulso
Custom models	Models trained on your brand or domain, plus the tests that show they hold up.	Chevalière
Product and interface design	Interfaces designed from research and checked against 168 principles before launch.	Interface Audit
Applied research	Synthetic panels that test a product decision before you pay to build it.	Maison
Launch	Site, search, paid, and AI-answer channels that bring the first users.	All three

Chevalière

The signet of the lab. A proprietary Bayesian engine, forged in Pulso, that scores every output against the bar set at the start of the project.

Nothing leaves unsealed.

Maison

Synthetic panels built for one client, one market, one question. They read a product decision before real users have to.

004 TailorsBuilt by people who decided to build something quieter.

006 QuestionsBefore you write

What does Vesti Labs build?

AI apps for web and iOS, agents and internal tools connected to your systems, custom models with their tests, and the design and launch work around them.

How is a lab different from an AI agency?

A lab ships its own products. We run Interface Audit, Dreszi, and Pulso, so the method you hire was used first on products we own, by the people who will work on yours.

How does an engagement start?

With a first read at no cost. If there is something worth building, the next step is an executive brief with a fixed scope and a fixed price.

Do you work outside Texas?

Yes. The lab is in Austin and works with teams across the United States and Latin America, in English and Spanish.
