Technology is the most powerful lever for human progress.

Estelalba is a family office. We invest our own capital in advanced technologies with the power to move society forward — companies where science becomes product, and where progress reaches people.

We work across Europe and the United States, close to the founders building at the frontier: artificial intelligence, deep tech, energy, high-performance computing, materials science, space systems, health, and sustainability.

We invest for the long term. We commit to the companies we believe in and stay for as long as it takes them to matter.

We measure success by two things at once: what a company returns, and what it changes. We do not believe these compete.

If you are building technology that will transform how humanity lives, works, and moves forward, we would like to meet you.
