Mangrove Partners
Nathaniel August launched Mangrove Partners in 2010 after stints at White Eagle Partners, Brahman Capital Partners, and Goldman Sachs. The firm describes itself as a value-oriented investment manager, not a single-family office. Mangrove invests across public equities, private credit, and special situations, blending fundamental analysis with event-driven and special-situations strategies. The team of 24 professionals includes dedicated quantitative and biotech specialists — Tiffany Marchell, PhD, joined in December 2023 to cover biotechnology. The firm does not disclose holdings or external GPs it backs. Mangrove maintains a single office at 2 Sound View Drive in Greenwich, Connecticut. In May 2024, the firm hired Jawaad Mahmood as Head of Quantitative Investments, a new role focused on systematic strategies (per firm website, 2024). The team added analysts Alex Warmath in September 2024 and Jim Tse in May 2024. Unlike many long-only value funds, Mangrove operates a hybrid structure that combines fundamental research with systematic quantitative models. The firm's mandate explicitly prioritizes avoiding permanent capital loss, which shapes its concentrated portfolio and willingness to hold cash when opportunities are scarce.
