Diameter Capital
Diameter Capital Partners LP is a New York-based alternative asset manager focused on the global credit markets, founded in 2017 by Scott Goodwin and Jonathan Lewinsohn. The firm manages approximately $13 billion in assets across multiple credit strategies, combining fundamental research with trading expertise and rigorous risk analytics to identify attractive opportunities across the credit cycle and capital structure. Diameter is an SEC-registered investment adviser and serves a diverse institutional investor base including pension funds, endowments, foundations, family offices, and sovereign wealth funds seeking differentiated exposure to the global corporate credit markets.
Diameter's investment platform is organized across several complementary strategies. The flagship long/short credit hedge fund invests across the full spectrum of corporate credit, from investment grade to distressed, in both public and private markets. The Diameter Dislocation Fund series provides institutional investors with access to a closed-end, drawdown fund format focused on dislocated performing credit, stressed situations, and distressed investments arising from micro-cyclical or macro-driven market disruptions. The firm also manages CLOs, CDOs, and a growing private credit platform that includes directly originated senior secured loans to middle-market companies. More recently, Diameter launched Diameter Dynamic Credit, a registered interval fund that extends its institutional credit expertise to individual investors and financial advisors.
Diameter Capital has earned a strong reputation among institutional credit investors for its dynamic, research-intensive approach to global credit investing and its consistent ability to navigate complex credit situations across market cycles. The firm's Dislocation Fund II, which closed at its $2.2 billion hard cap with approximately 50% new investor participation, reflects the strength of institutional demand for Diameter's differentiated credit capabilities. Diameter's combination of hedge fund agility, institutional research depth, CLO management expertise, and growing private credit capabilities make it one of the most comprehensive and respected credit-focused alternative investment managers of its generation.
