Custom software engineering
Custom software, from apps to artificial intelligence.
Web apps, iOS and Android apps and AI systems built around your business. You talk directly to the engineers.
An engineering company, not an agency.
MS Labs is a Brazilian custom software development company. We build web applications, iOS and Android apps and AI-powered systems designed around each client's process. We work remotely, in English or Portuguese, and you own the code we deliver.
How it works
Discovery
We understand the problem, the business and the constraints before talking technology.
Proposal
Scope by feature, timeline and budget agreed in writing.
Development
Frequent working releases you actually use, not status reports.
Launch and evolution
App store or web release, monitoring and ongoing maintenance.
Why MS Labs
You talk to the people writing the code
No account managers between your idea and the implementation. Technical decisions are explained in plain language.
You own the code
Repository, infrastructure and documentation are in your name. You are never locked in.
Scope and price in writing
Before we start, you get what will be delivered, in what order and what it costs.
Web, mobile and AI in one team
From the backend to the app stores to LLM integrations, without stitching vendors together.

Frequently asked questions
What is custom software development?
It is building a system from scratch around how your company works, instead of bending your process to an off-the-shelf product. You own the code and it evolves with the business.
What is the difference between custom software and off-the-shelf SaaS?
SaaS solves the average case for many companies and charges per seat. Custom software solves your specific case, integrates with what you already use and has no license fees. If an existing tool solves the problem well, it is usually the better choice.
How much does custom software cost?
It depends on scope: number of features, integrations, platforms (web, iOS, Android) and security requirements. After discovery you get a fixed price for a defined scope, before any commitment.
How long does development take?
It depends on the size of the first version. We recommend starting with the smallest version that solves the main problem, putting it into use and evolving it. The exact timeline comes in the proposal, with the delivery order.
Who owns the code?
You do. Repository, infrastructure, app store accounts and documentation are owned by your company.
