Why we started Aeternum Fund
A short note on conviction, timing, and technical researchers.
Backed by the scientists building frontier AI.
Approach
The best researchers often look like outliers early.
We believe the next generation of category-defining companies will come from technical researchers who start before the world agrees with them.
Aeternum Fund writes the first check — often before the work is shaped into a company — and brings patient capital, operator experience, and a global network.
Portfolio
Research-led companies we have backed.
