Who We Are

Our leadership team is driven by the opportunity to re-invent mortgage for the benefit of lenders, borrowers, investors, and communities.


Buck Collins

Co-Founder, Chief Executive Officer

Buck's vision of the mortgage market was borne out of his experience working hand in glove with industry pioneer Lewis S. Ranieri, the “father” of the mortgage-backed security. Formerly Managing Partner & COO of Ranieri Solutions, Buck was the key driver behind the creation of the Single-Family Rental REIT, Hyperion Homes, now known as Home Partners of America. His creative insight into the established mortgage ecosystem stems from a deep understanding of how its various constituents think, operate, and fit together.
