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.

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.

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.

The firm focuses on growth equity opportunities in financial services, payments, and technology-enabled businesses, reflecting the domain expertise of its investment team. Former partner Bryan Paul specialized in financials and payments coverage, a function likely maintained by the current team. The firm's public portfolio may include broader sector exposure, but private investment activity is concentrated where the partners can add value through board-level involvement or operational guidance.

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.

One Three One Partners operates as an asset manager, not a single-family office, which means it likely accepts external capital from limited partners alongside the founders' own co-investment. The specific composition of its LP base—whether institutional, family office, or high-net-worth—is not publicly detailed. The firm's structure as a partnership with significant founder co-investment is designed to align interests between the internal team and any external capital providers.

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.
