Vehicles, ranges, and the ground systems that make departure repeatable. Access to orbit is the threshold: without it, nothing else in the thesis compounds.

Frontier conviction. Long-term perspective.
We explore the technologies expanding what is possible—from access to orbit and satellite networks to the emerging potential of orbital computing.

Neptuno backs infrastructure and the ideas that give it purpose: systems that may shape the next era, and the founders building them.
Future-proof, in our language, is a philosophy. It means a long-term perspective and a bias toward resilience through change. It is not a guarantee of outcomes, and it is not a promise that capital is protected.
The thesis on this page is space. It does not recast Neptuno’s history as an exclusively space-focused record.
Our investment in SpaceX reflects our conviction in the new space age.
A long horizon is a discipline.
02 — Frontiers
Four directions organize the work. They are areas of inquiry, not a list of holdings. Neptuno does not manufacture spacecraft, and nothing here is a facility the firm owns.
01
Vehicles, ranges, and the ground systems that make departure repeatable. Access to orbit is the threshold: without it, nothing else in the thesis compounds.
02
Platforms, logistics, and servicing. The less visible layer that lets hardware remain useful once it is up — infrastructure in the older sense of the word.
03
Constellations and instruments that turn a vantage point into signal: communications, sensing, and timing that only orbit can provide.
04
Orbital data centers are an emerging thesis — the possibility that some computation may one day sit in orbit, closer to where data is gathered and under different limits on power and heat. It is early and unsettled. We do not describe it as a mature industry, and we do not describe it as Neptuno’s.

Founding Partner, Neptuno
Fabio Ribeiro is the Founding Partner of Neptuno. His experience spans technology, entrepreneurship and investing—from the early Brazilian internet to aviation and venture capital. He co-founded TUZ Ventures and brings a cross-disciplinary perspective to founders building at the frontier.

Neptuno welcomes a conversation with founders building in these frontiers, and with people who have an opportunity that belongs in the same thesis.
