PY & Co. · Client practice

Built like it’s ours.

Sites, apps, dashboards, and AI systems for clients, built with you to the standard we hold our own titles to, and kept running long after launch.

Your project is developed the way we develop our own: proven on paper before it is built in code, then refined until it holds.

The approach

The best tools for the work.

We use the best technologies and tools for each project. AI has made moving between them cheap, so we pick what fits the problem in front of us rather than pushing every project through the same ones, and we build on whichever model is strongest for the job. What you are buying is the judgment, not a set of tools.

Chosen per project
  • Language and framework
  • The model we build on
  • Where it runs
  • How it stores its data
Never up for negotiation
  • We build it ourselves
  • You own all of it
  • We do not ship what we would not sign
  • We do not disappear at launch

What we build

Four kinds of systems.

C.1

Sites & apps

From institutional sites to full web and native applications, engineered end to end.

C.2

Dashboards & internal tools

The systems your operation actually runs on: dashboards, admin panels, integrations.

C.3

AI systems

Agents and automations that do real work, wired into your processes with judgment.

C.4

Care & upkeep

We stay with what we ship: monitoring, fixes, and steady improvement.

The engagement

Three steps, start to finish.

01

Conversation

We start by understanding the problem. Direct, technical, with the founder in the room.

You leave with

A call, and the problem written back to you the way we understood it.

02

Vision

You approve the whole experience before we build it, in a written plan with fixed scope and an honest estimate.

You leave with

A plan you could hand to anyone, and a price that does not move.

03

Delivery

Working software in steady increments, with the founder one message away. And when it ships, we stay with it.

You leave with

The code, the keys, and the people who built it one message away.

Questions

What people ask.

What do you do?
Custom software development. Institutional sites, web and native applications, dashboards, integrations, agents and automations wired into your processes.
What does it cost?
It depends on the scope, and the number is in writing before any code. You get a plan with fixed scope and a price that does not move.
How long does it take?
The estimate is in that same plan. Delivery comes in steady increments, so you see software working early.
Where are you?
In Campinas, São Paulo, Brazil, and we work with clients here and abroad.
Who owns the code?
You do. The code, the keys, and the people who built it stay one message away.
What technologies do you use?
The best ones for each project. AI made switching between them cheap, so we pick what fits the problem in front of us.
