Middle Market Lending Companies: A 2026 Guide
Middle market lending companies are private lenders that finance mid-sized firms. Learn what they lend, who qualifies, how deals are matched, and what to ask.
Middle market lending companies are private credit firms and specialist lenders that make loans to mid-sized businesses, usually outside the traditional bank channel. Their borrowers are typically too large for small-business loans and too small for the public bond market. This guide explains who they are, what they lend, how a deal moves, and what to check before you apply.
What is middle market lending?
Middle market lending is lending to companies in the mid-sized band of the economy, where the lender typically sizes the loan to the company's earnings. Golub Capital describes a typical core middle market firm as fairly mature, with an average age of 31 years, 50 to 500 employees, and between $10 and $100 million in annual EBITDA (Golub Capital).
Historically, smaller companies in this band sourced capital from banks. Lord Abbett notes that companies with less than $100 million in annual earnings would have turned to banks, and that direct lending now sits outside the traditional banking system (Lord Abbett).
What is a middle market loan?
A middle market loan is a loan to a middle market company, usually larger than a small-business loan and sized from a few million dollars into the hundreds of millions. Most are senior secured loans from private funds, though the structure varies by deal. Thrive Funding, which arranges these loans without being the lender, accepts requests from $1 million and up, with most of its site focused on $5 million and above.
What are examples of middle market companies?
Examples include a fifty-person manufacturer with steady revenue, a regional distributor being bought out by its management, or a services firm refinancing debt before a growth push. What links them is the size band rather than the industry. Golub Capital estimates that the U.S. category includes approximately 200,000 companies, employing up to one-third of the U.S. workforce (Golub Capital).
Which are the largest middle market lenders?
No published list can rank them on one fair measure, so treat any "top five" list with care. Assets under management, deal counts and loan types all differ. Some firms that appear in industry rankings report figures that show their scale. Golub Capital had over 1,000 employees and over $80 billion in capital under management as of July 1, 2025, a gross measure that includes leverage (GrowthCap). AllianceBernstein says over $26.2 billion of its capital is available for acquisitions, leveraged buyouts, recapitalizations, refinancings and growth investments (AllianceBernstein).
The right lender depends on your deal size, sector, state and loan type more than on a firm's size. A large fund may not write a $3 million loan, and a small fund may not fund a $80 million acquisition.
What types of middle market financing are there?
Most middle market financing falls into a few families. The table below shows the common ones.
| Type | What it funds | Typical use |
|---|---|---|
| Senior debt | Core working capital or acquisition debt, first in line for repayment | Refinancing, growth, buyouts |
| Asset-based lending (ABL) | Loans sized against receivables, inventory or equipment | Businesses with strong collateral and seasonal cash needs |
| Mezzanine | Subordinated debt, often with equity-like features | Filling the gap between senior debt and equity |
| Acquisition financing | Debt to buy another company | Buyouts, add-on acquisitions |
Thrive Funding arranges all four of these types from its lending partners.
What's the difference between a TLA and a TLB?
A Term Loan A (TLA) is usually held by banks, amortizes on a schedule, and is often shorter in tenor. A Term Loan B (TLB) is typically sold to institutional investors, repays less during the loan's life, and carries a balloon at maturity. Both are term loans, so the difference lies mainly in who holds the loan and how it is repaid. Ask any lender which structure a proposed loan uses and how repayment is scheduled.
How does a middle market financing request get matched?
A request moves in five steps. The borrower applies, and the application becomes a lead. Thrive matches the lead against each lending group's criteria, including deal size, revenue and EBITDA minimums, industries, states, loan types and pricing. Matching groups receive an anonymous deal summary and reply yes or no. Once the borrower agrees, up to three groups that said yes receive introductions, best fit first, each in its own email thread.
The lender issues any term sheet on its own letterhead. Thrive then sends the borrower a side-by-side summary, and the borrower chooses one. Thrive's success fee is owed only when the loan closes. Thrive's fee comes from its lending partners, and every borrower email says so.
What should you check before you apply?
Before sending a request, confirm the loan size you need, your last two years of revenue and EBITDA, your industry, your state, and the loan type you want. Check whether a lender will decline you without a conversation. Ask who the lender is, whether it has the authority to fund, and what fees you will pay.
Read every term carefully. Estimates from an intermediary are indicative terms. They are not a term sheet, and they are not an offer. Only a lender's own term sheet should be treated as a proposal to accept.
