## Questions

### Who runs investment decisions at Guidepost Growth Equity?

Russ Sampson and Michael Sullivan co-lead the firm as Managing General Partners and sit on the investment committee. They built the firm after holding operating roles in scaling software companies. The partnership structure is flat — investment decisions are made by the two founding partners with input from the broader investment team, with no external advisory board.

### How does Guidepost Growth Equity source its deals?

Guidepost relies on a proprietary origination model built around direct outreach to bootstrapped founders and referrals from its network of technology operators. The firm explicitly avoids competitive auctions and banker-driven processes. Instead, it identifies capital-efficient software companies that have never hired an investment bank and initiates conversations around founder liquidity and growth acceleration.

### What investments does Guidepost Growth Equity avoid?

Guidepost does not invest in pre-revenue startups, venture-stage companies with venture-capital cap tables, or asset-heavy businesses outside software and technology-enabled services. The firm also avoids auction processes, hostile transactions, and sectors where it does not have direct operating experience. It explicitly screens out companies that have already taken institutional equity rounds.
