What O'Brien-Staley Partners does

O'Brien-Staley Partners (OSP) is a privately held, SEC-registered investment advisor founded in 2010 by Jerry O'Brien and Warren Staley, headquartered in Edina, Minnesota. The firm operates across four discrete financial business strategies: (1) alternative asset management focused on value investing in complex commercial and industrial credits, small and medium-sized enterprise loans, and commercial real estate, managing over $1 billion in assets under management for domestic institutional investors including university endowments, religious and hospital systems, and corporate and public pension plans; (2) market-rate impact investing launched in 2015, targeting fixed income credits in low- and moderate-income areas, energy efficiency projects, and affordable housing; (3) nationwide loan servicing through independent affiliate AmeriNat, LLC (founded 1975), which manages over $11 billion in loans and related deposits for approximately 300 government, quasi-governmental, financial institution, and non-profit clients across 47 states plus DC and Puerto Rico; and (4) deposit management through independent affiliate American Deposit Management Company (ADM, founded 2009), which manages over 1,100 accounts totaling $5.8 billion in FDIC-insured deposits for more than 300 treasury clients.

OSP monetizes primarily through alternative asset management fees earned as an SEC-registered investment advisor — with management fees and likely performance fees across its OSP Value Fund series — supplemented by fee revenue from AmeriNat's loan servicing platform and ADM's deposit management services. The firm has raised multiple funds including a $600 million vehicle in 2017 and OSP Value Fund IV in 2023. OSP is differentiated by the deep Cargill and CarVal Investors pedigree of its founders and senior team, providing 25+ years of specialized C&I credit underwriting experience and proprietary counterparty relationships with CFOs and CEOs at approximately 100 US banks.

The firm does not publicly disclose pricing or revenue figures, and operates as a small boutique (11-50 employees) with no proprietary technology platforms or AI/ML capabilities described in source materials. Distribution is relationship-driven: OSP sources institutional capital through direct relationships, quarterly check-ins with bank counterparties, and recurring investor events; AmeriNat and ADM operate as direct B2B service providers. In 2022, OSP expanded its impact platform via the acquisition of American Church Mortgage Company assets, and in 2024 completed a $61 million refinancing of Excelsior Crossings with Dry Creek Capital Partners, signaling continued cross-strategy deal activity.

Direct peers

• CarVal Investors: Cargill-affiliated alternative credit and loan portfolio manager and the firm where OSP's founders and most senior partners previously worked. It pursues the same 'unloved' C&I and CRE credit thesis and is the most direct strategic comparable to OSP's Value Investing business.
• Wayzata Investment Partners: Minnesota-based alternative credit manager focused on C&I, structured credit and special situations. OSP Managing Directors Derek Pitt and Christian Lundsgaard previously worked at Wayzata, making it a direct talent and strategy comparable.
• Whitebox Advisors: Minneapolis-based alternative asset manager with active credit, special situations and loan portfolio strategies. OSP's Director of Operations previously worked at Whitebox, and the firm is a direct regional comparable in distressed and event-driven credit.
• Castlelake LP: Alternative asset manager with real estate and specialty finance businesses including loan portfolio acquisitions and servicing. OSP's Head of Business Development (Etienne Laubignat) was previously Director at Castlelake, and the firm pursues overlapping special situations credit.
• Varde Partners: Global alternative investment firm with deep credit, distressed and loan portfolio mandates. OSP's Associate Director of Accounting came from Varde and the strategies (special situations, asset-based lending) materially overlap with OSP's value investing thesis.
• Chatham Asset Management: Special situations and high-yield credit manager with deep loan portfolio expertise. OSP's Managing Director Kevin Becker previously worked at Chatham and the firm is a direct comparable in opportunistic and loan-portfolio credit.
• Northern Pacific Group: Minneapolis-based private equity firm that invests alongside OSP in deals like the Excelsior Crossings refinancing. While primarily buyout-focused, it shares the regional base, institutional LP relationships and operating overlap with OSP's CRE credit strategies.

Broad incumbents

• Black River Asset Management: Cargill spin-off alternative investment manager with global credit and trading strategies. Multiple OSP professionals (Investor Relations, Operations) came from Black River, and the firms share the Cargill heritage and alternative credit DNA.
• Hamilton Lane: Large-scale private markets investment manager and advisor to institutional LPs (endowments, pensions, sovereigns). Comparable to OSP in serving the same institutional LP base, but at vastly greater scale and brand recognition, illustrating the headroom and competitive pressure on OSP.

Emerging players

• Corrib Capital Management: Special situations and event-driven credit manager. OSP's Managing Director Kevin Becker previously held roles at Corrib, and the firm represents an overlapping niche credit strategy though with smaller scale.
