Let's talk about
your project.
We build software the right way — which starts with a real conversation. Reach out by email or phone, tell us what you're working on, and we'll take it from there. No forms, no bots, no automated sales sequences. A human being will read your message.

Boituva / SP · CEP 18.550-802
Our studio is based in the greater Sorocaba region, but we operate entirely remotely. Every deliverable, sprint review, and feedback session runs asynchronously or via video call — distance has never been a barrier for us.
We work with companies and founders building real products — digital platforms, AI-powered applications, startup MVPs, and workflow automation. If you have an idea and need a team to design, build, or evolve it, this is the right place.
Not sure whether your project is a fit? Just describe what you're trying to solve. We'll give you an honest answer — and if we're not the right team for it, we'll say so.
All enquiries are treated with full confidentiality. We sign NDAs on request before any technical discussion. Your ideas stay yours.
We keep things simple
and direct.
No automated follow-up sequences, no sales pipeline drip. When you reach out, a person reads your message, considers it, and writes back.
First Reply
Every email sent to [email protected] receives a human response within one business day. Usually sooner. We acknowledge your message and ask any clarifying questions we need.
Initial Assessment
After a brief exchange, we share an honest read on scope, rough timeline, and whether the project is a strong fit for our studio. No commitment required on either side at this stage.
Proposal or Discovery Call
For projects that advance, we schedule a discovery session — 45 to 60 minutes, fully focused on understanding the problem space — before writing a single line of code or spec.
What makes a great first message.
You don't need a polished brief — just enough for us to understand the territory. Here's what helps.
What problem are you solving?
Describe the situation as you see it — the pain, the gap, the opportunity. You don't need to know the technical solution. That's our job. Even a single paragraph gives us a huge head start.
Who is it for?
Tell us about your intended users or customers. Are you building for your own internal team, for a specific industry, for consumers at scale? Understanding the audience shapes everything from architecture to UX.
Where are you in the process?
Is this a brand-new idea you need to validate? An existing product you want to rebuild or extend? A set of manual processes you need automated? Knowing the starting point lets us calibrate the right engagement model immediately.
Timeframe and rough budget range
If you have a target launch date or a budget ceiling, share it upfront. We won't disqualify you — we'll use the information to propose the most practical path forward, whether that's a lean MVP or a phased platform build.
How best to reach you back
Email works for most things, but if you prefer a voice call or a video session, just say so. Let us know your timezone if you're outside Brazil and we'll schedule around it without friction.
Got an idea?
Let's build it.
Drop us an email or pick up the phone. The first conversation costs nothing and commits to nothing — it's just the fastest way to find out what's possible.
