The proof

Two products in production

The timelines below are the actual ones, not portfolio averages.

25DAYS

Cárgame

Two mobile apps on iOS and Android — one for customers, one for carriers — plus a backend API and a tracking CMS.

Both apps, the backend and the CMS delivered in 25 days. Winner of the SENA Fondo Emprender grant.

The process

How we do it in 30 days

Four stages with dates on them. You know what ships and what does not before we start.

Day 0 – 2 01

Scope locked

We define what goes into the MVP and, more importantly, what does not. You get a written feature list and the final price. If it does not fit in 30 days, you hear it here — not in week three.

Day 3 – 20 02

Build

Every Friday you get a link to a working build, not a status report. You talk directly to the person writing the code.

Day 21 – 27 03

Real data and load

We load your actual data, test with real users and fix what breaks. Things break here, not in production.

Day 28 – 30 04

Production

Deployment, app store submission where it applies, and handover of the repository and infrastructure under your name.

Fixed price

We quote the outcome, not the hours

One number before we start. If it takes us twice the work, that is our problem, not your invoice.

One number

The price is set on day 2 alongside the written scope. No hourly rate, no retainer that runs dry halfway through.

50% upfront, 50% on delivery

If it is not working at day 30, we do not invoice the second half.

Change requests priced upfront

Anything outside the written list gets quoted and approved before we build it. It never shows up on the invoice as a surprise.

Everything under your name

Repository, servers and service accounts are created with your credentials. You are never locked into us to keep it running.

For agencies

Overflow capacity under your brand

If you sold more than your team can ship this quarter, we come in as part of your team.

White label

We work under your brand. Your client never knows we exist, and we never contact them unless you ask us to.

We take the overflow

A full project or a single module. Engaged per delivery — no annual contract, no monthly minimum.

We work inside your process

Your repository, your board, your code standards, your reviews. We do not ask you to change how your team ships.

Your working hours

Cali, Colombia sits 0 to 3 hours from every US time zone. Standups happen when your team is online, in English.

Capabilities

What we build

What goes into a 30-day MVP. These are not separate service lines — it is the same team on the same project.

Web apps and admin panels

Reizen's back office handles 100,000 database operations a day in production.

React Angular Laravel Node.js

iOS and Android apps

One codebase, both stores. The Reizen apps have 230,000+ downloads; the Cárgame pair shipped in 25 days.

Flutter iOS Android

AWS infrastructure

The same architecture that carries Reizen traffic, sized so you are not overpaying while the product finds traction.

Lambda EC2 S3 RDS

AI inside the product

Language and vision models wired into your system. It is also why we ship in 30 days instead of six months.

LLM Computer vision ML

Stalled project rescue

An audit of a project that stopped moving: what it costs to finish it and what it costs to rewrite it, with numbers, in one week.

Audit Modernization

AI in production

The same AI that gets it shipped in 30 days.
