About Aether
We take calculated risks
to make the world safer.

Aether is a pre-seed and seed stage fund investing in the companies building the next generation of defense and dual-use technology. We back founders solving hard problems at the intersection of innovation and national security.

We invest across defense technologies, aerospace, autonomous systems, cyber, and adjacent sectors where technological advantage translates into strategic impact. We enter early, when the risk is real and the stakes are highest.

We operate with a long horizon, a lean structure, and a conviction that private capital has a role to play in making the world more secure.
