What we do

The kinds of sites we build

  • Company website
  • Landing page for ads
  • Local business website
  • Online store and e-commerce
  • Corporate site with many pages
  • Authority and portfolio site

Never a template

Your site is designed from scratch. No competitor will have anything like it.

Genuinely fast

Above 90 on Google's own speed test. A slow site loses customers before it even appears.

Built to generate contact

Every block on the page exists for a reason: to get the visitor to message you or request a quote.

Custom software

From the messy spreadsheet to live indicators

That outdated spreadsheet, full of duplicate versions and broken formulas, becomes a system that generates reports, dashboards and indicators on its own.

How it works

From first contact to going live

You know which stage you're in the whole time, and approve before each step forward.

  1. 01

    Conversation

    30 minutes to understand your business and what you need. No cost.

  2. 02

    Quote

    Scope, timeline and price in writing within 24 hours. What's on paper is what counts.

  3. 03

    Design

    We show you how it will look before coding. You approve or ask for changes.

  4. 04

    Build

    We build what was approved, with you following the progress.

  5. 05

    Review

    You test it and flag anything to adjust. Two rounds included.

  6. 06

    Delivery

    Live, with recorded training and 30 days of support included.

What sets us apart

Six promises with consequences for us

Anyone can promise quality. These are the ones we put in the contract.

Deadlines in the contract, not in conversation

The delivery date goes in writing. If we cause a delay, you hear about it in advance and you don't pay for it.

The site and the code are yours

Domain in your name and source code handed over on request. Want to switch providers one day? You can, without rebuilding anything.

Fast site or we fix it free

We deliver above 90 on Google's speed test. If it falls short, we fix it at no charge.

You talk to whoever builds it

No account managers and no support tickets. The person replying is the one with your project in hand.

Our mistakes aren't billable

Anything broken in what we built is fixed at no cost, inside or outside the 30 day support window.

We say no when no is right

If a cheap ready-made tool solves your case, we say so instead of selling a bigger project than you need.

By the numbers

The scale of what we've built

Every number here comes from a project in the portfolio and can be checked on its own page.

17screens in a single system

Stack Labs ERP — from prospecting to recurring revenue, all on one database. It's the system Stack Labs itself runs on every day.

14 daysfrom first commit to live

LifeOS — 45 screens, 12 modules and 34 tables, with public signup open in two weeks. A whole product, not a pretty screen.

9buttons, 9 ready-written messages

Elite Estofados — every point on the page opens WhatsApp with its own text, so the conversation starts already knowing which service the customer wants.

16pages in two languages

Rolls-Royce — four models, eight brand sections and the legal pages, tuned from a 375px phone to a 1920px monitor.

Monthly estimate

We use a range of 15% to 35% conversion increase for sites rebuilt with a focus on speed and clarity. That sits well below what market studies would allow us to project — we would rather reality beat the estimate than the other way around.

This is an estimate to support a decision, not a promise of results. What actually happens depends on your market, your offer and factors beyond the website.

Testimonials

What the people who've worked with us say

One so far — and it's real: a name, a business and a live project you can open right now.

I used to depend on word of mouth. Now the site shows up on Google and people reach my WhatsApp having found me there, already knowing what they want and willing to pay for a job done properly. The number of quote requests I get each week has multiplied, and a far bigger share of them close — because people arrive already convinced by what they saw on the page.

Why we built LifeOS

The problem is always the same: the bills in a spreadsheet, the tasks in an app, the deadlines in the phone calendar — and none of them knows that the year-end goal depends on what's left of the salary. LifeOS merges all of it into one app and shows, before the month starts, where every unit of currency goes. We don't have a user testimonial cleared for publication yet: create a free account and judge for yourself.

Published with the client's permission. The gains he mentions are his own account, based on WhatsApp activity and his calendar — there is no analytics tool installed on the site. The project is live and can be checked through the link.

FAQ

Frequently asked questions.

Didn't find your answer? Message us on WhatsApp — we usually reply within minutes.

Message on WhatsApp
  • It depends on size: how many pages, whether you need an online store, a client area or a connection to other software. A single page costs far less than a full site. We talk for 30 minutes, understand what you need and send a fixed price within 24 hours — free and with no commitment.

  • A landing page takes 7 to 14 days. A full company website takes 15 to 30 days. Software varies with size, and the first useful version usually ships in 3 to 6 weeks. The deadline is set in the proposal before we start and holds as a commitment.

  • Yes. Most visits now come from phones, so we design for the small screen first and only then scale up to tablet and desktop. We test on several devices before delivery.

  • We do both, and it's half of what we do. We build customer and sales tracking, orders, online booking, dashboards of your business numbers and automation of repetitive work — always shaped around how your company already works.

  • Every project ships technically prepared for Google to understand and display your site, and that's the foundation for ranking well. Nobody honest guarantees a first position, because Google decides and it also depends on your industry's competition. What we guarantee is that your site won't lose position because of a technical fault on our side.

  • Yes, 30 days of support included in the project price. After that, any fault in something we built is still fixed at no cost. Monthly maintenance is available as an option for continuous improvements, but it's optional.

  • Yes, we work with companies across Brazil and abroad. Video calls and messaging work well, and most projects run that way from start to finish. Around Pará de Minas, Divinópolis and Belo Horizonte we also meet in person.

  • No. You pay for the project and it's yours. Domain and hosting carry a small annual cost you can pay directly to the provider. We don't charge per user and we don't lock you into any platform.
