Eighteen48 Partners

Eighteen48 Partners was established in 2019 by Julien Sevaux and Tarek AbuZayyad, both former partners at Stanhope Capital, the independent multi-family office Sevaux founded in 2004. The firm was designed to serve the principals' own families and long-standing clients, operating an independent model focused purely on compounding wealth. The ownership is distributed among partners, clients, and employees, ensuring that internal capital is invested on identical terms. The firm employs a long-term, endowment-style investment approach that emphasizes concentration over broad diversification. It builds portfolios across public equities, private equity, growth capital, and direct co-investments. Confirmed direct co-investment positions include high-growth enterprises. The investment committee is chaired by external specialists, including Mark Baumgartner, CIO of the University of Florida Investment Corporation, and Robert Durden, CEO/CIO of UVIMCO. The firm deploys capital across Europe, North America, and Asia. The team is supported by a network of senior advisors with deep institutional pedigrees. Investment committee members also include Kathleen Jacobs, CIO of RWJBarnabas Health, and Larry Kochard, CIO of Makena Capital Management. Paulo Eapen, formerly head of Europe and Asia for Blackstone Credit, sits on the firm's board. In May 2024, the firm continued to operate with its core London-based team, leveraging its network for deal sourcing and due diligence. The firm's structural differentiator is its hybrid model: it is neither a pure single-family office nor a conventional multi-family office, but an independent investment office wholly owned by its user base. This aligns the firm's own balance sheet directly with client outcomes and attracts an investment committee composed of sitting endowment and foundation CIOs, a governance feature that distinguishes it from most externally-owned wealth managers.

Frequently asked questions

How is Eighteen48 Partners structured, and who owns it?

Eighteen48 Partners is wholly owned by its partners, clients, and employees. It was designed as an independent Investment Office, not a conventional multi-family office or a fund manager. This structure aims to eliminate conflicts of interest by ensuring the firm's capital is invested on the exact same terms as its clients' capital.

Who runs investment decisions at Eighteen48 Partners?

Co-founders Julien Sevaux (CEO) and Tarek AbuZayyad lead the firm, supported by Investment Director Edward Clive. The firm convenes a high-profile Investment Committee to support its decision-making. This committee includes sitting endowment CIOs Mark Baumgartner (UFICO), Robert Durden (UVIMCO), and Kathleen Jacobs (RWJBarnabas Health), as well as Larry Kochard of Makena Capital Management.

What investment approach does Eighteen48 Partners use?

The firm employs a long-term, endowment-style investment model inspired by leading US university endowments. It rejects market timing and over-diversification. Instead, it focuses on constructing a concentrated portfolio of high-quality, growth-oriented businesses across public equities, private equity, and growth capital, with the goal of compounding capital over decades.

How does Eighteen48 Partners source its private deals?

The firm sources proprietary deal flow primarily through its extensive network of partners, clients, and senior advisors. Senior team members have direct private equity experience from firms like Apax Partners, Rhone Capital, and Greater Pacific Capital. This network facilitates direct co-investments and access to specialized fund managers that are typically difficult for most investors to reach.

Does Eighteen48 Partners manage money for a single family or is it open to others?

Although founded to serve the partners' own families and long-standing clients, the firm accepts external institutional capital. It describes itself as serving 'multi-generational family and institutional capital.' However, it operates with the focus and alignment of a private investment office, distinguishing itself from a large-scale, distributed asset manager.
