## Questions

### Who runs investment decisions at Ulex Partners?

Sean Dennihan, the firm's founder and managing partner, leads investment decisions alongside partner Michael O'Donnell. Dennihan previously worked in Vista Equity Partners' credit division before launching Ulex. No investment committee beyond the two named partners has been disclosed.

### How does Ulex source proprietary deal flow?

Ulex leans on Dennihan's network from Vista's credit ecosystem and Texas-based technology banking circles for sourcing. The firm targets founder-owned mid-market software companies in the US Sunbelt, a segment where relationships with regional operators and bootstrapped founders matter more than broad auction processes. No intermediary-placement data has been published.

### What revenue range does Ulex target in a prospective portfolio company?

Ulex targets companies generating between $2 million and $15 million in annual revenue, per the firm's publicly stated criteria. This sits below the threshold of most large-cap technology private equity funds and above the seed-stage venture market, placing Ulex in the lower mid-market growth equity segment.
