Meet Marc.

Marc Bui is a Co-Founder of MambaCap Financial, leading the company’s financial strategy and operational infrastructure. With a career in the mortgage industry dating back to 1999, Marc has built a track record spanning some of the industry’s largest platforms, earning his reputation as both a top producer and a trusted leader long before co-founding MambaCap.

His clientele includes first-time buyers, move-up buyers, and seasoned real estate investors, and what sets him apart is his ability to bring fresh perspectives to client scenarios and introduce mortgage solutions that most people have never considered before — solutions designed to maximize each client’s financial position, whether they are purchasing their very first home or adding a fifth investment property to their portfolio.

His approach is never about pushing a product. It is about helping people see possibilities they did not know existed — until they look back and wish someone had shown them sooner.

Marc is a producing leader in his own right, closing tens of millions in personal volume alongside running the business. Beyond the loan file, he has built a substantial following across the industry as one of mortgage’s most active voices on social media, regularly sharing insights and mentoring fellow originators on business growth and content creation.

A husband and father of two, Marc brings the same grounded and straightforward approach to everything he does: show up, do the work, and make it make sense for the person in front of you.
