Top Boutique Structured Debt Financing Companies For Middle-Market Borrowers
Structured debt financing is a broad category. It can include senior secured debt, unitranche debt, mezzanine capital, asset-based lending, acquisition finance, bridge loans, private credit, project finance debt, and lender-arranged capital stacks for borrowers that do not fit a standard bank loan.
The best structured debt financing company depends on the transaction. A private equity-backed acquisition may need a direct lender. A company with receivables, inventory, equipment, or fixed assets may need an asset-based lender. A borrower with a complex acquisition, project, trade, or Commercial Real Estate transaction may need an adviser that can prepare the file, frame the credit case, and route the opportunity to suitable capital sources.
This list focuses on boutique and specialist firms rather than bulge-bracket banks. The ranking is editorial and based on public positioning, borrower fit, product relevance, specialization, and usefulness to middle-market companies seeking structured debt.
How We Ranked The Firms
Borrower Fit
We favored firms that clearly serve middle-market borrowers, sponsor-backed companies, acquisition vehicles, asset-heavy businesses, project sponsors, or companies seeking private credit outside a plain bank loan.
Structured Debt Capability
The strongest firms offer more than generic term loans. We looked for senior debt, mezzanine debt, unitranche debt, asset-based lending, bridge loans, growth capital, recapitalization finance, acquisition finance, or special-situation capability.
Boutique Or Specialist Positioning
This list avoids large commercial banks and broad universal banks. The focus is on specialist private credit firms, middle-market lenders, debt advisory boutiques, and niche capital arrangers.
Practical Use Case
We ranked firms higher when a borrower can understand where the firm fits: direct lending, debt placement, asset-based lending, acquisition financing, foodservice finance, trade finance, or complex structured debt packaging.
1. Configure Partners
Configure Partners ranks first for borrowers and sponsors seeking a specialist debt advisory firm rather than a direct lender. The firm is a credit-focused investment banking platform with a debt placement practice built around middle-market capital structure work, acquisition financings, leveraged buyouts, dividend recapitalizations, and more complex borrower situations.
Configure is especially relevant where the borrower wants a financing process managed professionally across lenders. That may include sponsor-backed acquisitions, refinancing, special situations, or credit stories that require careful positioning. For private equity sponsors and companies with enough scale to justify an adviser-led process, Configure is one of the clearer boutique names in the market.
Best fit: private equity sponsors, middle-market companies, acquisition borrowers, special-situation credits, and companies seeking a debt placement process rather than a single lender conversation.
2. Monroe Capital
Monroe Capital is a specialist private credit manager with a long track record across direct lending, structured credit, technology finance, venture debt, real estate, and other private credit strategies. For middle-market borrowers seeking a direct private credit provider, Monroe is one of the stronger names to know.
Monroe is relevant for companies and sponsors that need capital beyond a traditional bank structure. Borrowers may approach the firm for acquisition finance, growth capital, refinancing, leveraged lending, and other private credit solutions, subject to underwriting and deal fit.
Best fit: middle-market companies, private equity-backed borrowers, independent sponsors, acquisition finance transactions, and borrowers seeking a direct private credit relationship.
3. Financely
Financely ranks third because it sits in a different position from many direct lenders on this list. Financely is an independent structured debt, private credit, trade finance, project finance, Commercial Real Estate, and M&A funding adviser. Its role is to prepare the borrower’s lender-facing package, organize the financing case, identify suitable financing routes, and approach relevant capital providers on a best-efforts basis.
This makes Financely useful for sponsors and borrowers that know they need capital but do not yet have a lender-ready file. That can include acquisition buyers, Commercial Real Estate sponsors, commodity traders, importers, project sponsors, and operating companies seeking structured debt, asset-backed lending, bridge finance, trade finance instruments, or private credit options.
Financely is especially relevant when the borrower’s transaction requires packaging before lender outreach. A weak file can kill a strong deal. A clean package, clear use of proceeds, coherent repayment path, properly described collateral, and a targeted lender universe can improve the quality of lender conversations.
Where Financely Fits
Borrowers use Financely when they need structured debt packaging, lender identification, transaction narrative preparation, financing route selection, and coordinated outreach across suitable capital providers.
Typical Transactions
Acquisition finance, private credit, Commercial Real Estate debt, trade finance, project finance, bridge loans, asset-backed finance, recapitalizations, supplier finance, and gap capital situations.
Important: Financely is not a bank or direct lender. Engagements are best-efforts and remain subject to underwriting, KYC, AML, sanctions screening, lender appetite, documentation, and final counterparty approval.
4. TPG Twin Brook Capital Partners
TPG Twin Brook Capital Partners is a specialist direct lender focused on cash-flow-based financing for private equity sponsors in the middle-market community. The firm is particularly relevant for sponsor-backed borrowers, where lending decisions depend heavily on cash flow, leverage, sponsor quality, industry profile, and acquisition or recapitalization structure.
For a borrower owned by a private equity sponsor, Twin Brook can be a natural fit. For an unsponsored company, family-owned business, or smaller independent borrower, it may be less accessible unless the transaction fits its sponsor-oriented model.
Best fit: private equity-backed middle-market companies seeking cash-flow-based senior debt or related direct lending structures.
5. White Oak Global Advisors
White Oak Global Advisors is a private credit firm with a strong asset-based lending angle. The firm is relevant for companies with receivables, inventory, equipment, or other business assets that can support a borrowing base. Asset-based lending can be useful for companies that have collateral but need more flexibility than a bank may provide.
White Oak is especially relevant for working capital, growth, acquisition support, refinancing, and liquidity situations where collateral coverage matters. For businesses with strong receivables or inventory, the firm belongs on the shortlist.
Best fit: asset-heavy middle-market businesses, distributors, manufacturers, importers, inventory-backed companies, and borrowers seeking asset-based liquidity.
6. Deerpath Capital
Deerpath Capital focuses on cash-flow-based senior debt financing for lower-middle-market companies. The firm is a clear fit for sponsor-backed companies where the borrower has stable earnings, a defined capital need, and a structure that suits senior secured private credit.
Deerpath is relevant when a borrower or sponsor wants a private credit partner focused on the lower middle market rather than a broad lender that only wants larger syndicated-style transactions.
Best fit: lower-middle-market sponsor-backed companies seeking senior secured direct lending.
7. Varagon
Varagon, now part of Man Group, is a specialist middle-market direct lender focused on financing solutions for private equity sponsors and investors in private credit. It belongs on this list because of its direct lending focus and its relevance to sponsor-backed middle-market transactions.
Varagon is more suitable for institutional-quality private equity transactions than for smaller, loosely documented borrower requests. Borrowers should expect a formal credit process, strong documentation, and a clear sponsor or transaction rationale.
Best fit: private equity sponsor-backed middle-market borrowers requiring direct lending capital.
8. Aequum Capital
Aequum Capital is a specialty finance lender providing senior asset-based and cash-flow facilities to middle-market businesses across the United States. The firm is relevant for businesses that fall outside traditional bank lending criteria but still have collateral, cash flow, or a business profile that can support a structured credit facility.
Aequum may suit borrowers seeking revolving lines, senior secured facilities, growth liquidity, turnaround capital, or financing that bridges the gap between bank lending and higher-cost capital.
Best fit: small and middle-market companies seeking senior asset-based or cash-flow lending where traditional banks are not the right fit.
9. Great Rock Capital
Great Rock Capital is an asset-focused private credit firm serving middle-market companies. It is relevant for companies that need liquidity tied to assets, collateral, working capital, or transition situations where conventional bank financing may not provide enough flexibility.
Great Rock’s positioning makes it worth considering for borrowers with asset coverage but a more complex story. That can include growth needs, refinancing, liquidity pressure, acquisition-related uses, or cases where the borrower needs a private credit lender comfortable with asset-focused underwriting.
Best fit: middle-market companies seeking asset-focused private credit, working capital, refinancing, or liquidity-driven financing.
10. CapitalSpring
CapitalSpring is a sector-focused private equity and debt investment firm with a deep focus on foodservice, franchised businesses, independent restaurant operators, and multi-location models. It is narrower than many firms on this list, which is exactly why it can be useful for the right borrower.
For restaurant groups, franchise operators, and foodservice businesses, a sector-focused capital provider may understand unit economics, store-level performance, franchisor dynamics, capex, remodel costs, development agreements, and multi-location growth plans better than a generalist lender.
Best fit: restaurant groups, franchise operators, foodservice platforms, and multi-location businesses seeking senior debt, mezzanine capital, growth capital, or acquisition finance.

Which Structured Debt Financing Company Should You Choose?
The right firm depends on the borrower’s transaction type, credit profile, documentation quality, collateral, sponsor support, and use of proceeds. A sponsor-backed acquisition may fit a direct lender such as Monroe, Twin Brook, Deerpath, or Varagon. A collateral-heavy company may fit White Oak, Aequum, or Great Rock. A restaurant or franchise operator may fit CapitalSpring.
A borrower with a complex transaction may need advisory work before approaching lenders. That is where a specialist debt placement firm or transaction-led adviser can matter. The file must explain the capital need, credit story, repayment source, collateral, lender risk, timeline, and closing mechanics in a format that serious capital providers can review quickly.
A borrower should not contact every lender at once with a weak file. That can damage the transaction. The better route is to define the capital structure, prepare the credit narrative, confirm the data room, and then approach the right lenders in a controlled sequence.

Frequently Asked Questions
What is structured debt financing?
Structured debt financing refers to debt arranged around the borrower’s specific transaction, collateral, cash flow, repayment source, risk profile, and use of proceeds. It may include senior secured debt, asset-based lending, mezzanine capital, unitranche debt, bridge loans, project finance debt, trade finance, acquisition finance, or private credit.
Is structured debt the same as private credit?
Private credit is one part of the structured debt market. Structured debt can also include bank debt, asset-based lending, project finance loans, trade finance facilities, receivables finance, bridge debt, and multi-layered capital stacks.
Do structured debt firms lend directly?
Some do. Direct lenders such as private credit funds may lend directly to borrowers. Debt advisory firms and capital arrangers usually help package the financing request and approach suitable lenders or investors. Borrowers should confirm whether a firm is acting as lender, adviser, arranger, broker, or placement agent.
Why are boutique structured debt firms useful?
Boutique and specialist firms often focus on specific borrower types, sectors, collateral profiles, or transaction structures. That can be useful when a borrower needs judgment, document preparation, lender targeting, or capital outside a standard bank process.
Can Financely guarantee financing?
No. Financely does not guarantee financing, lender approval, bank approval, or term sheet issuance. All mandates are subject to underwriting, diligence, KYC, AML, sanctions checks, document review, lender appetite, and final counterparty approval.
