About AC Alcateia

Technology with method, from the first conversation to ongoing improvement.

AC Alcateia is a digital solutions company that brings together web and mobile development, websites and marketing. Every project starts by understanding the business and ends with a live product, measured and ready to evolve.

Why AC Alcateia

  • Technical decisions explained clearly

    Every technical decision is explained in plain language, including what it changes in timeline, cost and maintenance.

  • Web, mobile and marketing, integrated

    Website, system, app and social media planned together, with the same identity and the same rules, without juggling several vendors.

  • Performance and SEO from the foundation

    Pages delivered pre-rendered, optimized images and structured data: speed and search treated as requirements, not as a final tweak.

  • Code another team can carry on

    Organized architecture, tests on critical flows and documented decisions. The product is never held hostage by a single person.

  • Quotes without fine print

    What changes the price is stated upfront: scope, integrations, publishing and maintenance. You know exactly what you are hiring.

  • Remote service across Brazil

    Video meetings and continuous follow-up, with timelines, support and code handover defined in writing in the proposal.

How we work

  1. First conversation

    You tell us the challenge, who will use it and what already exists. The first conversation is free of charge.

  2. Scope and proposal

    We define what goes into the first version and what comes later. For systems and apps, this scoping happens in the technical assessment, a paid step. The proposal covers scope, working format and timeline.

  3. Building in stages

    The product grows through short deliveries that you follow and test from early on.

  4. Launch and evolution

    Publishing to the stores or the web, follow-up after launch and evolution based on real usage.

Cases

Live projects you can check for yourself.

Client projects, our own products and a social project, with the context, scope and technologies of each one.

Partnerships

Two ways to build together.

For those who sell digital projects and for those who want to launch a product with a technical partner.

  1. Conversation
  2. Evaluation
  3. Agreement
  4. Building

Every partnership goes through a feasibility review and starts with responsibilities, timelines and terms formalized in a contract.

How each partnership works

Frequently asked questions

Before we talk.

Does AC Alcateia build apps for Android and iOS?

Yes. Apps are built with React Native, covering Android and iOS from a single codebase, including publishing to the App Store and Google Play.

What is the difference between a website and a web system?

A website presents the company: it is built to load fast, be found on Google and turn visits into leads. A web system runs the business: it has logins, rules, records and integrations, and is used every day by the people who work with it.

Can you take over a project that is already live?

Yes. AC Alcateia evolves apps and systems that already have users: new features, fixes, refactoring of problem areas and tests on the flows that cannot break. Before any evolution proposal, the project goes through the technical assessment, a paid step.

Which engagement formats are available?

Fixed-scope projects, allocation to your product or team for a set period and on-demand consulting by the hour.

How does the quote work?

It all starts with a free conversation. Websites and catalogs have reference prices, published on the pricing page; custom systems and apps go through the technical assessment, a paid step that defines what to build before the proposal.

Do you work with companies in other cities?

Yes. Service is remote, with video meetings and continuous follow-up for companies across Brazil.
