## Questions

### Who runs investment decisions at One Three One Partners?

Founders Francois Drouin and Thomas Twiggs jointly oversee investment decisions, supported by a lean team drawn from institutions including Citadel, Brookfield Asset Management, Morgan Stanley, and Lone Pine Capital. The partnership structure concentrates decision rights with the founders, who have worked together across multiple market cycles and asset classes. The firm's small size gives them the flexibility to move capital quickly between public and private positions without committee delays typical of larger asset managers.

### What is the relationship between One Three One Partners and Citadel?

One Three One Partners is an independent firm founded by two former Citadel portfolio managers, Francois Drouin and Thomas Twiggs. Citadel Investment Group is not an investor in or affiliate of One Three One Partners. The founding team's Citadel pedigree is operationally relevant because it means the firm runs with the same risk-management discipline and talent-recruitment standards that characterize the broader 'Tiger Cub' and Citadel alumni network. Several team members—including Head Trader Ted Vickers—also previously worked at Citadel.

### Does One Three One Partners invest in both public and private companies?

Yes. The firm operates a hybrid mandate that includes public equities, private growth equity investments, and special situations. This cross-market capability allows the team to source opportunities in both listed and unlisted companies, often within the same sectors. The founders' backgrounds at Citadel (predominantly liquid markets) and Brookfield (private infrastructure and credit) provide the operational range needed to execute this strategy.

### How does One Three One Partners source its investment opportunities?

The firm sources opportunities through the professional networks its principals built over decades at Citadel, Brookfield, Morgan Stanley, and Lone Pine Capital. This network-based origination model—common among former hedge fund managers operating in the lower middle market—emphasizes relationship-driven access over auction processes. The firm's concentration on financial services and technology sectors further narrows the sourcing funnel to areas where the team has deep industry contacts and overlapping diligence expertise.

### What is the significance of the 160 Ted Turner Drive property?

One Three One Partners holds a commercial real estate asset located at 160 Ted Turner Drive NW in downtown Atlanta, Georgia. The property represents a direct real estate investment layered onto the firm's primary focus on corporate growth equity. This asset is held separately from the firm's fund structure and reflects the partners' willingness to deploy capital opportunistically across asset classes.
