We dig down to what matters.

Goethita is a software engineering house. It builds products of its own, with rules that are proven before they reach the screen, and is getting ready to build yours.

Two open seams.

Every product starts with a real problem, and only leaves the mine once its rules can carry the weight.

ALKMIA In use · early stage

Training guided by data.

A training and endurance platform. It logs every set, suggests the load for the next one and adjusts the week to what you actually did. The name comes from the Greek akmē (ἀκμή), the highest point.

Team tasks, without losing the thread.

It began as a desktop application. It is becoming a web platform for many companies, with a board, deadlines, priorities and owners, updated in real time.

Goethite FeO(OH)

−120 m The name

A mineral named after a poet.

The mineral

Goethite is an iron oxyhydroxide, FeO(OH). It is the basis of the yellow ochres used for centuries as pigment, and a material of industrial interest.

The honoree

Johann Georg Lenz named it in 1806 in honour of Johann Wolfgang von Goethe, who studied mineralogy and wrote about nature with the same rigour he brought to poetry.

Science and literature in one name. That is the principle behind the company.

−140 m The miner

A miner from Minas Gerais.

Goethita was founded by Rodrigo Costa, born in Minas Gerais, Brazil. People from Minas are called mineiros, and in Portuguese the same word means miner: someone who digs into the earth to understand what it hides.

The company's name closes the circle. Goethite is found in Ouro Preto, one of the historic towns of Minas, and the ALKMIA triangle takes its proportions from the triangle on the Minas Gerais flag.

Passionate about engineering and technology, nature and the open air, the arts and classical literature, he builds products that bring these passions together. ALKMIA was the first, and its story is the first chapter of Goethita.

−160 m Principles

Rules first. Screens second.

Before we design an interface, we write the rules and prove them. What you see is the last layer, not the first.

Rules that are proven

The numbers that matter come from reproducible arithmetic, tested case by case. No result depends on a guess turning out right.

Refusals are tested too

Every permission is checked on what it must let through and on what it must refuse, with the reason for the refusal confirmed.

Built to last

History that cannot be erased, data that stays yours, and only the dependencies that earn their place.
