YieldStack opens co-brokerage program for commercial mortgage brokers

YieldStack, an AI-driven commercial mortgage broker and financing marketplace, is taking applications for a co-brokerage program that lets approved independent brokers keep their client relationship and set their own fee. The New York-based company says the model gives brokers its lender matching and execution support without requiring upfront payment.

Why it matters: - Independent commercial mortgage brokers can now outsource lender matching and deal execution while staying in control of the client relationship. - The program is designed to give brokers an alternative to building a full back office or buying software that still leaves closing work on their desk. - YieldStack says the structure lets brokers earn fees only when a loan closes, which reduces upfront risk.

What happened: - YieldStack opened applications for a co-brokerage program on August 14, 2026. - Approved independent commercial mortgage brokers and capital advisors can use YieldStack's matching, packaging and execution support under their own name. - The program is application-only, with no self-serve signup. - YieldStack reviews each application and issues a platform invitation to approved firms. - Approved co-brokers add their own fee on top of YieldStack's fee and co-sign the brokerage agreement as an Additional Broker. - The borrower sees the stacked fee inside the engagement agreement.

The details: - YieldStack is an AI-native commercial mortgage broker and financing marketplace, not a lender. - The platform matches submitted deals against more than 5,000 loan programs. - YieldStack says the median time to a first lender offer is under an hour. - The company says it filters for a small set of lenders that are actually positioned to fund a transaction competitively. - YieldStack's Broker fee is 0.50% to 1.00% of the loan amount, paid by the borrower at closing. - The co-broker's fee is also disclosed and paid at closing. - There is $0 upfront. - Nothing is owed if the loan does not close. - Every credit decision is made by the participating lender. - Approved co-brokers operate under their own authority. - The program does not confer, extend or substitute for any license or registration. - Each participating firm remains responsible for its own licensing and compliance in the states where it does business. - Independent commercial mortgage brokers and capital advisors can apply at More information. - YieldStack was featured in Bisnow's July 2026 national capital-markets coverage of AI-driven mortgage matchmakers in the middle market.

Between the lines: - YieldStack is positioning the program as a services model, not just software. - Co-founder and CTO Rommin Adl said, "It's not software as a service. It's outcome as a service." - Co-founder and CEO Daniel Chesney said the company tries to match each deal to only the lenders built to fund it competitively. - The narrow distribution strategy aims to preserve lender attention, which YieldStack treats as the scarce resource in commercial mortgage finance. - The move also gives independent brokers a way to participate in YieldStack's process without giving up their own brand or fee control.

What's next: - YieldStack will continue reviewing applications individually. - Approved firms will be contacted with a platform invitation. - If adopted, the program could expand YieldStack's role from broker and marketplace to a back-end execution layer for other independent brokers.

The bottom line: - YieldStack is betting that brokers will trade software tools for a turnkey deal team if they can keep the client, keep control of fees and pay only when a loan closes.
