Enterprise venture studio

Backing the next enterprise journey.

Roomack is a selective studio founded by Adison Mackay. We partner with early-stage operators — especially those coming through the Y Combinator ecosystem — who are building the infrastructure companies of tomorrow.

The founder

Adison Mackay

A young founder on an enterprise journey, Adison works closely with technical teams at the earliest stages. His approach is patient, hands-on, and focused on the long climb rather than the quick headline.

Through Roomack, he invests his own capital — backed by his family — alongside a small network of operators who have built and sold enterprise companies before.

That combination of family capital and operator experience gives Roomack the patience to back founders for the long climb, without the pressure of traditional fund timelines.
