## Questions

### Who runs investment decisions at Erie Street?

Erie Street was founded in 2018 by Terry Graunke, who assembled a team of operators with more than 30 years of experience launching, buying, and selling business services companies. The firm does not name a distinct CIO or managing partner beyond Graunke in its public disclosures; investment decisions appear to flow through the senior team that designs and executes the four operational workstreams.

### How does Erie Street source proprietary deal flow?

The firm describes its approach as founder-focused, positioning itself as an alternative to traditional private equity. Rather than running a broad auction-process pipeline, Erie Street attracts founders seeking operational transformation alongside capital, and it draws on the 60-plus family offices in its network for proprietary introductions to service-company owners.

### Does Erie Street participate in fund commitments or only direct deals?

Erie Street’s disclosed activity focuses on direct control buyouts and structured growth partnerships in business services companies. The firm has not disclosed any fund-of-funds activity or third-party GP commitments. The capital backing its deals comes from its own network of family offices rather than from multi-investor commingled funds.

### How is Erie Street related to Lacey Lake Leadership?

Erie Street works closely with Lacey Lake Leadership, a human-capital partner that collaborates on executive searches, talent strategy, and team-building for Erie Street’s portfolio companies. Lacey Lake Leadership is not a subsidiary of Erie Street; the firm characterizes the relationship as a partnership that strengthens its ability to invest in people at portfolio organizations.

### Where does the underlying capital come from?

Erie Street is backed not by a single fortune but by a curated network of more than 60 family offices (per the firm’s website, accessed 2026-05-29). The firm describes this capital as warm and patient, enabling it to hold businesses outside conventional private equity time frames. No individual family or named principal wealth origin has been publicly disclosed.
