Donum Dei Capital

Investing for Humanity

BARCELONA · EST. 2020

OUR PURPOSE

We bring together human intelligence, frontier technology and capital — in service of humanity.

Intelligence

Knowledge, experience and judgment, earned over decades of building companies.

Technology

Artificial intelligence, blockchain and digital assets — researched, designed and coded in-house.

Capital

Markets, private investments and real businesses, held with a long horizon.

Our ventures and investments are built to create lasting value — and what they earn, we invest again in businesses and projects that help humanity. We aim to do well by doing good.

WHAT GUIDES US

Truth

We say what we see, including what is inconvenient.

Generosity

What we earn is meant to be shared.

Courage

We build where others wait.

Work

Rigor every day, especially when no one is watching.

We create, own and answer for what we build.

We work with our own capital, so our purpose remains our own.
