Anyone can build a product with AI. Almost no one knows how to scale it.

The invisible 90% decides if you grow or die quietly.

Let's make a real product

I design and build products that scale. If you already have a prototype, I turn it into a market-ready product; if not, we build it from scratch.

From idea or prototype to product

If a prototype already exists, I turn it into a market-ready product. If not, I design and build it from the start. The outcome is the same: it ranks, performs, keeps accounts secure, and retains the people who use it.

01

SEO & positioning

Technical audits, structured data, and content architecture so your product actually shows up when people search for it.

02

Infrastructure optimization

Right-sized hosting, caching, and cost control — so traffic spikes don't break the product or the budget.

03

Auth & security

Real login flows, session handling, and data protection — the trust layer users never see but always feel.

04

UX & retention

Interfaces refined with real usage data — and the brand that carries them. The difference between people trying a product once and paying for it every month.

Work

Who's behind this

Hi 👋, I’m Stiven Martínez, co-founder of GuruHotel, Inc. I also build other brands and experimental products that generate impact automatically, and help shape the future of Short Term Rentals at Hospy.ai

I have spent more than twelve years designing and building digital products and brands, from the first version to products in market.

My work sits at the intersection of design, product, and development. I cover identity, interface, and implementation with one standard, from start to finish.

I have taken part in products that reached millions of users and generated consistent revenue, sustained over time and not only at launch.

Ready for a product that exists for real?

Tell me what you have — or what you want to build. On a short call we see the invisible 90% and the next step.

Is this for me? +

Yes, if you have an idea, a prototype, or a half-built product and want it in market — without hiring a full team. Founders and small teams. Brand, product, or both.

Digital product, branding, or both? +

Both, and usually together. Identity, interface, and the webapp people actually use. A brand with no product behind it, or a product with no standard, isn’t the work.

I have an AI prototype. Does that already scale? +

Almost never. Scale here is the invisible 90%: it gets found, it holds, it charges, it retains. SEO, infra, auth, and UX — not more screens.

From scratch, or only if something already exists? +

Both. If there’s nothing yet, I design and build. If there’s a prototype, I turn it into a market product. Same standard either way.

How do we start? +

Send me one line: product, brand, or both. On a short conversation we check fit and the next step.
