## Questions

### Who runs investment decisions at Main Post Partners?

Co-founders Jeff Mills and Sean Honey lead the firm's investment committee and make all final capital allocation decisions. Both previously spent their careers at Weston Presidio, where they developed a concentration in consumer and multi-unit business investing. Their partnership structure means no external investment committee members influence deal approvals.

### How does Main Post Partners source proprietary deal flow?

The firm relies on a network built over two decades by Mills and Honey in the consumer and services sectors. Relationships with regional investment banks, commercial bankers, and founder referrals drive origination. Main Post does not run a centralized outreach function and has publicly emphasized its preference for off-market introductions over intermediated auctions.

### Does Main Post Partners participate in fund commitments or only direct deals?

Main Post conducts direct control and minority investments from its own committed capital pools. It does not operate as a fund-of-funds, nor does it publicly allocate to other private equity firms as a limited partner. All capital is deployed directly into operating companies.

### Which sectors does Main Post Partners explicitly avoid?

The firm has not disclosed a formal exclusion list, but its investment history shows no healthcare, financial services, real estate, or technology infrastructure deals. Its consumer concentration excludes luxury and fashion, focusing instead on accessible-price-point products, services, and multi-unit retail concepts.

### How is Main Post Partners related to Weston Presidio?

Main Post was founded by two former Weston Presidio professionals, Jeff Mills and Sean Honey, who left the firm in 2014. There is no formal affiliation or shared ownership between the entities. The founders' investment philosophy carries forward Weston Presidio's consumer and operational focus, applied to smaller transactions.

### What is Main Post Partners' known posture on co-investments alongside external GPs?

Main Post evaluates co-investments on a deal-by-deal basis and has historically collaborated with like-minded consumer-focused investors. However, the firm tends to lead transactions where it can control governance. No standing co-investment program with specific external GPs has been publicly disclosed.
