## Questions

### Who runs investment decisions at Southbox?

Founder Jon Gosier serves as Executive Partner of Southbox Capital. Managing Partner RJ Joshi oversees day-to-day deal activity alongside Partners Chandler Heinz Laun — who also serves as Chief of Staff — Jonathan Hecht, and Marcus Glover, who leads Southbox Ventures. The team operates with Gosier as the central decision-maker, drawing on a network that includes co-investors such as the SCADpro fund.

### How does Southbox source entertainment deals?

Southbox operates two complementary entities — Southbox Entertainment, which provides equity and mezzanine financing, and FilmHedge, which extends senior debt. Founder Jon Gosier has a direct presence at industry events, including the Cannes Film Festival, and the firm leverages relationships with academic institutions like the Savannah College of Art and Design to access production pipelines and emerging talent. Publicly confirmed sourcing includes strategic partnerships and outbound deal evaluation rather than open-market submissions.

### Is Southbox structured as a film fund or a diversified holding company?

Southbox is a multi-strategy investment company, not a pure-play film fund. Beyond its entertainment-finance division, the firm owns commercial real estate — including a gym in the Bronx, an office building in downtown Atlanta, and a mixed-use affordable-housing project in Philadelphia — and holds early-stage blockchain and cryptocurrency startup exposure plus a literary division. This generalist structure differentiates it from dedicated media-finance vehicles.

### Does Southbox participate in fund commitments or only direct deals?

Southbox deploys capital directly: it provides early-stage equity and mezzanine financing to individual film and television productions, and it holds direct positions in early-stage technology startups. There is no public evidence of the firm acting as a limited partner in third-party funds; confirmed co-investment activity is project-based, as seen in its collaboration with the SCADpro fund on the feature film *Collateral Data*.

### What is the relationship between Southbox and FilmHedge?

FilmHedge is a sister company co-founded by Mickey Vetter, who is also a named Business Partner at Southbox Capital. Southbox Entertainment provides early-stage equity and mezzanine financing to productions, while FilmHedge extends senior debt to the same asset class. The two companies share talent and operate in coordination, but they remain distinct legal entities with separate capital stacks and product lines.

### How is Southbox related to the Savannah College of Art and Design?

The SCADpro fund acts as a co-investor with Southbox, and SCAD faculty and students contribute production resources — notably the university’s LED volume stages in Atlanta — to Southbox-backed films. Founder Jon Gosier is a SCAD alumnus, and the January 2023 partnership around *Collateral Data* marked the first feature film to use the institution's XR stage for principal photography, with students serving as crew and building digital environments.
