(01) The studio

It will feel like we're already on your team.

What you see from the first week. The examples below are illustrative.

  • Present

    You hear how it is going before you ask. One update a week, always from the same person.

    2. Ready to testTue 15:40

    Fast

    You see it working in days, not months. Small changes, the same day.

    We propose improvements with the why and the cost. The last word is always yours.

(04) Who you work with

You talk to the person who does the work.

No account managers in the middle. José is on every call, from the first sketch to the last deploy. We use AI to move faster; José reviews and signs every delivery.

“José understood our ideas and turned them into the product. He was proactive, and very clear when he explained the UX and UI vision.”
Santiago Carignano · CTO, AyronOne and Ayron Data

(05) How we work

Four steps, agreed before we start.

  1. Day 1

    We map the problem

    A 30-minute call. You tell us what is going on; we find what actually needs solving.

  2. Within 48 h

    We fix the scope

    A written proposal within 48 h: deliverables, dates and price.

  3. Weekly reviews

    We design and validate

    You see progress at the reviews we agreed on, and we validate against the scope.

  4. Launch

    We build and launch

    We build it, ship it and hand it over. Then we stay if you need us.

(06) From Argentina

Remote by design. Rooted in Mendoza.

José works from Mendoza, at the foot of the Andes. Calls, files and deploys all happen online, so founders in any city, from Argentina to New York, work with us as if we were next door.

Before you book.

Something else? Ask José on Telegram →
How fast can we start?
Express ships in a week or less, with two slots a week. Product Design starts within 48 h of the approved proposal; other plans get their start date in the proposal.
How do payments work?
Plans are paid in two parts on Contra, each held in escrow until you approve it. Express is paid upfront, and the Retainer monthly.
Who owns the work?
You do. Files, code and video are yours once the project is paid.
What time zone do you work in?
Argentina hours (GMT-3), and José shifts an hour to overlap with yours. If async suits you better, we work that way.

Launching soon? Let's talk.

You leave the call knowing what to build first and what it costs. The written proposal follows within 48 h, whether you hire us or not.
