An announcement gives the size of the round, not the size of this investor's cheque: the only rounds that imply a cheque are those where they were the sole named investor.

## The team

Named by the firm itself, on a filing, its Form ADV or its company registration **4 named**

We also hold **14** people at this firm from the lists this database was built from: a weaker source than the filings, since a list does not say when a title ended. Login to see them.

## What the register says

From the firm's own filings with the SEC, which it must file accurately by law

**$855M** gross assets of its funds Oct 2026

**Exempt** reporting adviser venture or small private funds

- **Legal name:** Fifty Years Industries, LLC

## What they claim to have backed

From their own portfolio page (on their website)

**5** of 5 we have independently watched raise

Weaker than a round we watched, stronger than a list somebody sold us. A firm is far less willing to put a company on its own site that it never funded.
