In short
Mix Labs is a Brazilian software studio building custom systems, integrations, and legacy migrations for companies abroad. Our working day overlaps with both US coasts and most of Europe, contracts are in USD or EUR, and you own the code and the infrastructure from day one — no lock-in, no proprietary runtime.
Why a Brazilian team, specifically
- Time zone: São Paulo is UTC−3 — one to two hours from New York, four to five from London. A question asked in the morning is answered the same morning, not the next day
- No overnight handoff: the work happens while you are awake, so blockers get resolved in conversation instead of in a ticket queue
- Engineers who have run production systems, not just built them — the team led engineering at dealership groups, marketplaces, and multi-unit retail before this
- Contracts in USD or EUR, invoiced from a Brazilian entity with the paperwork your finance team expects
- You own everything: source, infrastructure, and deployment. We do not host your product on anything you cannot take with you
What we build
How we work
Every engagement starts with a diagnosis, not a proposal. We read the systems that already exist, talk to the people who operate them, and come back with what we found — including the parts where the answer is that you do not need us.
We do not replace systems that work. An ERP that handles invoicing correctly stays; a dealer management system that satisfies the manufacturer stays. The work is almost always the layer around them — the integration, the capture, the reconciliation — because that is where the money leaks and where off-the-shelf products are weakest.
Delivery is continuous and visible. You get access to the repository from the first commit, environments you control, and a working increment every week rather than a milestone every quarter.
Frequently asked
How does the time difference actually work?
São Paulo is UTC−3, which is one hour ahead of New York in the northern summer and two in the winter. Our afternoon is London's evening. In practice you get four to six hours of live overlap with the US East Coast and three to four with most of Europe — enough for a daily conversation rather than an asynchronous relay.
Who owns the code and the infrastructure?
You do, from the first commit. Repositories live in your organization, cloud accounts are yours, and deployment runs on infrastructure you can access without us. We do not build on a proprietary runtime you would have to migrate off later — a vendor who can be replaced is a vendor worth keeping.
What happens when the engagement ends?
You keep a system your own team can maintain: documented architecture, tests that describe the behaviour, and no dependency on a person. If you want us to stay for support we will, but the handover is designed to work without that — a system that only we can run is a system we built badly.
Do you work in English?
Yes. Documentation, code comments, commits, and meetings in English as a matter of course for international engagements. The team has worked with distributed stakeholders long enough to know that 'we speak English' and 'we communicate well in writing' are different claims — you can judge the second one from the first call.
What size of company do you usually work with?
Mid-market companies with real operational complexity: a sales force spread across locations, systems accumulated over a decade, or a process that no product on the market matches. Below that, off-the-shelf software is usually the right call and we will say so.
