What people ask before signing.
The questions that come up in every first conversation, answered straight.
What does G R Tecnologia do?
G R Tecnologia (brand name GROCHA Tech) builds custom software: mobile apps, websites and landing pages, web systems and SaaS, games, applied artificial intelligence and brand identity. It is based in Santa Bárbara D'Oeste, São Paulo, Brazil, works remotely and has been in business since 2020.
How much does it cost to build a website or app?
It depends on the scope, and each quote is put together case by case after a short conversation about what the system needs to do. The price and the timeline come in writing before work starts, and talking to us costs nothing and commits you to nothing.
Do you work with clients outside Santa Bárbara D'Oeste?
Yes. The work is remote and has already been delivered to clients in several Brazilian states. Meetings happen over video calls and the project is followed up by WhatsApp and email, with partial deliveries so you can watch the product take shape before the end.
How long does it take?
A landing page is ready in days; an app or system usually takes from a few weeks to a few months, depending on its size. The timeline is agreed before work begins, along with what goes into each stage — and you get working versions along the way instead of waiting until the end to see anything.
Do I own the code at the end?
Yes. The source code of what you hire us to build is handed over to you, with no license fee or subscription to keep using it. For projects made with GR Builder, you download a static package with HTML, CSS, JavaScript and images that can be published on any hosting provider.
Do you take care of hosting and the domain?
We can, but it is not included by default. Hosting and domain registration are contracted separately, and you can keep everything in your company’s name — that way you stay in control of what is yours and never depend on us to switch providers one day.
Do you use artificial intelligence in your projects?
Yes, when it solves a real business problem: customer-service triage, document reading, content generation and assistants that carry out tasks inside the system. Several of our own products already run AI in production, including Tempestivo (legal), RevaMed (healthcare) and GR Contábil (accounting).
How do I start a project?
