About the firm

We started this firm because we wanted to be invested in by a firm like this one.

Origin

A smaller, slower kind of fund.

Cinder Grove began in 2019 as a single memo, written on a long flight by our founding partner Elena Marsh after a decade of building consumer companies. The memo argued for a firm that valued judgment over volume — a place built around six investors, not sixty.

Seven LPs read the first draft. They wired the first checks within a month. We've been building quietly ever since: forty companies across two funds, four sectors, and one very long table in a converted warehouse in Brooklyn.

We are not a platform. We are not a brand. We are a small group of people who like founders, like writing, and like the slow compounding work of building real companies.

Philosophy

Four values we keep returning to.

Curiosity over certainty

We'd rather be the firm asking the better question than the firm with the louder answer.

Craft over scale

We do fewer deals, write fewer memos, and read every page twice.

Truth over comfort

Honest feedback, said kindly, given early. The hardest gift to give a founder, and the most valuable.

Patience over urgency

Companies are built in decades. Hype is built in days. We pick the longer clock.

Investment principles

How we decide. How we follow on. How we leave a company better than we found it.

I

Conviction is a feature.

We lead or co-lead. If we're in, we're meaningfully in.

II

Reserves are a promise.

Half of every fund is held for follow-on. We back our winners.

III

Exits are a side effect.

We focus on building. The rest takes care of itself.

The long view
