How long does a project take?

It depends on complexity: a landing page is ready in 1 to 2 weeks; a full system takes 1 to 3 months. In the initial assessment we build a realistic schedule with partial deliveries. You see the system working before the end, not only on the last day.

How does the free assessment work?

It's a 30-minute video call. We listen to how the operation runs, find where it hurts, and tell you whether the problem is technology or process. You leave with a written assessment and practical recommendations. No commitment, no pitch.

What size companies do you work with?

From startups to mid-sized companies. What matters isn't size. It's the intent to grow with technology instead of hiring more people to patch the gaps. We've delivered for clients in Brazil, the USA, Australia, Peru, and Spain.

Do you disappear after delivery?

No. Every project ships with a warranty period and support included. For teams that need continuous evolution, monitoring, and on-call support, we offer maintenance plans. The people who built it keep looking after it.

What's the difference between simple and advanced automation?

Simple automation is a fixed rule: when X happens, trigger Y (say, an automatic report every Monday). Advanced automation uses AI to interpret language, decide, and act. It is an agent that reads the customer's message, understands the intent, queries the system, and answers. The first saves time; the second replaces a support shift.

How much does it cost? How do you charge?

We don't publish a fixed price list, because every operation has a different bottleneck. After the free assessment you get a scope with a fixed price per stage, no surprises halfway through. Smaller projects are usually a one-time fee; ongoing operations (infrastructure, AI, support) work as a monthly retainer.

Do I keep my data and my source code?

Yes. The source code and the data belong to your company, hosted in accounts you control. We sign an NDA when needed, handle personal data under LGPD, and hand over documentation so another team could take over. You are never locked in to us.

Do you also handle servers, networking and security?

We do. That is exactly what separates us from an agency: beyond development, we build infrastructure and networks, configure AWS, Azure, and Microsoft 365, and run penetration tests to find the hole before someone outside does.

Salles Dev did not start from a business plan. It started from a problem nobody wanted to fix. With no investor and no team, our founder built his own SaaS from scratch and learned the hard way what a bad Friday night deploy really costs. That product is still live and brings in R$20k in monthly recurring revenue across real estate and healthcare.

That changes how we look at your project. People who only sell services think launch day is the end. People who run a product know it is the beginning: the server goes down after launch, the customer writes at 11pm after launch, the security hole shows up after launch. So we became a team of specialists in infrastructure, cloud, development, AI and offensive security (pentesting). An agency ships the website and disappears. We stay with the server, the system and the customer conversation.

Our mission: turn technology into real business outcomes, from the server to the customer reply, with no jargon and no drama.
