About Martin County Business Exchange (MCBE)

Founded in 1986, the Martin County Business Exchange is one of the Treasure Coast’s longest-standing business networks. We are a non-political, not-for-profit business club headquartered in Stuart, Florida, and our Members represent a diverse cross-section of industries.

Membership is both selective and coveted—only one Member per business category is admitted, ensuring that every referral carries the weight of trust and exclusivity. This unique structure has helped MCBE maintain a reputation for excellence, where consumers and local businesses alike know they are connecting with the best of the best on the Treasure Coast.

Our Members are not obligated to refer business, yet referrals happen naturally and consistently. Why? Because every Member holds themselves to the highest standard of ethics, quality, and service—making recommendations a matter of pride, not policy.

The MCBE Mission

Our mission is to empower each Member to achieve the highest level of business excellence. Through collaboration, peer learning, and mutual respect, MCBE cultivates a culture where experience, innovation, and trust converge to strengthen both our Members and the communities they serve.
