How we work
Hiring a software team shouldn't be an act of faith. So we put it in writing.
Every project starts with a contract that fixes scope, milestones and dates, and a fixed price that doesn't move. We invoice legally, we answer within 24 business hours, and we stand behind what we deliver with a 90-day warranty. None of that is a favour — it's the baseline.
Solutions
A complete company, division by division.
From code to infrastructure: apps, e-commerce, systems, AI, cybersecurity, servers and maintenance. All under contract, fixed price and warranty.
Native apps
We ship your app to the App Store and Google Play.

Request a proposalWarranty and backing
What we sign, we honour in writing.
Four commitments that live in the contract, not on a landing page. If one isn't met, you have a document to hold us to.
Signed before we start
Contract with scope, milestones and dates
Before anything begins you sign a document stating exactly what gets delivered, in how many stages, and on what date each one lands. No grey areas.
No hourly billing
Fixed price, no surprise hours
The number you approve is the number you pay. If you ask for something outside the scope, it gets quoted separately and in writing before anyone touches it.
90 days
90-day post-delivery warranty
Any fault in what we delivered gets fixed at no charge for 90 days after delivery. It isn't a courtesy — it's in the contract.
Invoicing + 24 h response
Registered company, with invoicing
We invoice every payment legally and respond within 24 business hours. You get a receipt, a named counterpart, and someone to hold accountable.

How we work
Three stages, every one with a date.
A process built so you always know what is being done, when it ships and what it costs. No progress reports that say nothing.
01
Diagnosis and proposal
One call to understand your operation. You leave with a written proposal: scope, stages, dates and a fixed price.
NO COST02
Contract and build
Signed, then started. Every stage closes with something working that you can open and try yourself.
DATED STAGES03
Delivery and warranty
Production deploy, handover of every access, and training for your team. The 90-day warranty starts from there.

FAQ
What everyone asks before signing.
We don't publish prices because scope sets the number. What is fixed: you get a written proposal with a closed price before signing, and that number doesn't move. If you ask for something outside the scope mid-project, it's quoted separately and also in writing.
Detailed scope, stages with delivery dates, fixed price, payment terms and the 90-day post-delivery warranty. You read it before signing and you keep a copy.
Any error or fault in what we delivered: we fix it at no charge for 90 days after delivery. It doesn't cover new features or scope changes, which are quoted separately.
Yes. We're a registered company and we invoice every payment on the project. You have proper documentation from start to finish.
Within 24 business hours, committed in the contract. During the project you have a direct line to whoever is building, not a generic inbox.
Yes, and without asking. The portfolio projects are online right now: go in, browse the catalog, add something to the cart. None of them is a mockup.
Yes. We work fully remote with documented processes, so distance doesn't change how we work. Invoicing and payment terms are agreed before signing.
Yes. We hold verified developer accounts and handle the whole publishing process: listings, screenshots, privacy forms, signed builds and updates.
Yes — it's a division of its own. Software architecture, Docker, AWS, VPS, networking, CI/CD, monitoring and ongoing maintenance, plus cybersecurity audits, hardening, backups and certificates. We can run your entire infrastructure or work alongside your current provider.
In Baradero, Buenos Aires, Argentina. Several of our clients are local businesses that know us in person, and we work remotely with companies across the country and abroad.
Both. The portfolio ranges from a 24/7 convenience store and clothing shops to a factory with 40 years of history. The criterion isn't size: it's a clear problem worth solving.
