“Selling a business should be exciting, rewarding, and straightforward—not exhausting. I help business owners nationwide connect with qualified international investors, protect their legacy, and achieve the exit they genuinely deserve.” — David Mayfair, Business Sales Advisor

For founders and business owners across the country, a company isn’t just a financial asset—it’s a lifetime of hard work, long hours, and personal sacrifice. Yet nationally, only about 12% of listed small-to-medium businesses actually sell.

To David, that statistic isn’t acceptable. As an active Business Sales Advisor in California, David represents a rare 1-in-87,000 specialization across the state’s nearly 39 million residents—giving sellers access to an exceptional level of dealcraft, focus, and precision.

To ensure his clients receive unmatched representation, David aligned his practice with SD Business Advisors—recognized nationally as a premier advisory office for transaction success rates and radical ethical standards. Operating seamlessly via remote advisory across all 50 states, David pairs high-touch care with an international network of 35,000+ buyers, family offices, and international investors to generate maximum competitive tension for your exit.

A Lifelong Passion For Business & Connections

David’s passion for enterprise started early and runs deep through his family roots—from ancestors settling in California during the 1850s expansion to a father who built successful restaurant chains, ran an airline charter, and served on corporate boards.

  • 1993 (Age 14): Launched his first catalog mail-order business, hiring friends on commission and quickly growing to need six team members just to keep up with order fulfillment.

  • 2000 (Buyer-Side Roots): Started working on the buyer’s side of acquisitions. Learning firsthand how global and domestic acquirers evaluate risk and calculate value gave David a rare “buyer’s eye” advantage that he uses as a Business Sales Advisor for sellers today.

  • Present Day: Serving as a Business Sales Advisor headquartered in Palo Alto, representing seller clients nationwide while leveraging an elite global investor network affiliated with SD Business Advisors.

Based in Palo Alto, California, and San Diego, California, serving business owners nationwide with our global buyer reach.
