About Haven Mercer
What is Haven Mercer?
Haven Mercer is a New York-based financial services company that delivers differentiated financial products and solutions to our customers.
Haven Mercer was founded on the belief that there are better ways to provide financial services. We are identifying these and building them.
Today, we are standardizing a new exit pathway for internal ownership transitions of founder and family-owned businesses in the US.
With our approach, we are transforming installment sales / seller finance into an institutional-grade financial asset and the option of first resort for internal ownership transitions.

What Does Haven Mercer Do?
Through Managed Credit Ownership Transitions (MCOTs), Haven Mercer serves as the lender on behalf of sellers who use installment sales to transfer ownership internally.
Arms-length intermediation sets fair terms and durable structures built for success, with potential for liquidity or credit enhancement through a centralized platform.
We manage every stage of an installment sale, from initial underwriting through the final payment.
