Curitiba, Brazil

Built with AI. Owned by people.

We design and build web and mobile apps. Development is AI-assisted, and a person reviews every change.

What we do

Apps for the browser and for phones: the interface, accounts, and the parts that have to keep working after delivery.

Sites and single pages with a clear structure, written for the person who has to understand the offer.

A first version of a product: the core flow, accounts, and a codebase that can keep growing.

Connections between tools you already use, and small internal tools that take a repeated task off the week.

What is in, and what is out, is written down before building starts.

We use AI tooling while building. The tooling does not approve the work.

Every change is reviewed by a person before it moves forward.

You see the work running along the way, not only at the end.

Software DNA2Tech builds and runs.

Group trips, without the mess. For friends, couples and family.

It is meant to be used together with the LGPD.
