About us

Two people,
one shared vision.

GuiIsa was born from the partnership of Guilherme and Isabella in 2024 — a couple united by a passion for technology and building things that actually matter.

We operate as a tech holding, developing software products, hardware solutions, and consulting services under a single brand with a clear identity: precise, modern, and human.
