What One William Street Capital does
One William Street Capital Management, L.P. (OWS) is a New York-based, 100% employee-owned registered investment adviser founded in 2008 by David Sherr. The firm manages more than $8.5 billion in assets under management across multiple strategies focused primarily on asset-based and structured credit opportunities in North America and Europe, organized into four broad categories: fundamental credit, relative value, event-driven, and loan opportunities. OWS serves a global, primarily institutional investor base that includes pension funds and sovereign wealth funds, distributing its strategies through direct institutional sales, customized investment solutions, and a wholly-owned direct lending subsidiary (OWS Real Estate Finance, LLC) that originates, underwrites, and services commercial mortgages as a standalone business.
OWS's investment platform is anchored by proprietary credit and risk models and analytics infrastructure used to evaluate trade opportunities and capture portfolio risk measures across a wide range of fundamental and market scenarios. Operational risk is managed through internal controls audited annually under SOC I Type II, covering valuation, liquidity, counterparty relationships, and trade allocations. The investment approach combines a fundamental value framework with quantitative risk and return metrics, supported by a 130+ person team (70+ investment professionals and 60+ in operations, accounting, legal, compliance, tax, and technology). The firm has expanded into consumer and embedded-finance credit, including capital partnerships with Affirm (cumulative ~$4 billion of Affirm-originated assets since 2021) and Parafin (a 2026 credit facility co-led with Goldman Sachs).
The firm earns recurring investment management fees on AUM across commingled and custom strategies, plus fees from asset management, advisory, and direct lending services. As a private, employee-owned adviser, OWS does not publish a fee schedule; terms are disclosed privately via offering memoranda to permitted investors. OWS has been SEC-registered since June 2009, CFTC-registered as a Commodity Pool Operator since January 2013, and has been a signatory to the UN Principles for Responsible Investment since September 2017.

One William Street Capital competitors and assessment
Company assessmentDirect peers
- Octagon Credit Investors: Specialized CLO and structured credit manager with a long-tenured institutional LP base. Directly comparable on the structured-credit/leveraged-finance axis, with similar sub-$10B AUM profile and pension/sovereign wealth client mix.
- Waterfall Asset Management: Structured credit and ABS-focused manager with significant exposure to residential and commercial mortgage-backed securities, CLOs, and consumer credit. Same primary asset class (structured/asset-based credit) and similar institutional LP base as OWS.
- Crayhill Capital Management: Alternative credit manager focused on asset-based finance, ABS, and structured credit opportunities with an institutional investor base. Highly comparable in mandate, AUM tier, and strategy mix to OWS.
- Marathon Asset Management: Alternative credit manager with credit, asset-based, and structured product strategies serving institutional investors. Overlapping product set (structured credit, securitized products, asset-based lending) and similar institutional GTM motion as OWS.
- Sound Point Capital Management: Direct peer in structured credit and alternative credit strategies, with comparable CLO/asset-based credit focus and similar mid-sized AUM. OWS's CFO Crystal Frumberg previously served as Deputy CFO at Sound Point, underscoring direct talent and product overlap.
- Marblegate Asset Management: Direct peer focused on asset-based lending and special-situations credit to middle-market and specialty finance borrowers. Comparable mandate scope, investor base (institutional pensions, insurers), and direct-lending orientation to OWS's structured credit and OWS Real Estate Finance subsidiary.
- Pretium Partners: Specialty finance and asset-based credit manager with deep residential and commercial mortgage exposure, including forward-flow purchases from non-bank originators. Directly comparable to OWS Real Estate Finance and OWS's broader asset-based credit mandate.
Broad incumbents
- Angelo Gordon (TPG Angelo Gordon): Large multi-strategy alternative credit and structured products platform now part of TPG. Competes for the same institutional structured credit and asset-based mandates as OWS, with broader product breadth and post-TPG capital backing.
- Cerberus Capital Management: Larger multi-strategy alternative manager with significant asset-based, structured credit, and mortgage exposure (including the former Springleaf/OneMain platform). Multiple OWS team members previously at Cerberus (Frumberg, Epes-era alumni connections), and Cerberus competes for many of the same institutional mandates.
- PIMCO: One of the world's largest fixed income and structured credit managers, with deep ABS, CLO, and asset-based strategies. Competes with OWS for pension and sovereign wealth mandates in structured credit, though at much greater AUM scale and breadth.
