...because all of them carry several copies of your business cards around with them. When they meet someone who could use your products or services, they hand out your card and recommend you.*  It's as simple as that!  It's simple because it's based on a proven concept by BNI Founder, Dr Ivan Misner, called "givers gain."  If I give you business you'll give me business and we'll both benefit as a result.

It does so by providing an environment in which you develop personal relationships with dozens of other qualified business professionals. By establishing this "formal" relationship with other people, you will have the opportunity to substantially increase your business.

 
(*) Note, some professions, specifically attorneys and certain health care professionals, may not be permitted to seek direct referrals through in-person solicitation through the use of business cards pursuant to their ethical code.  Members of BNI that belong to these professions are directed to follow their profession's own ethical guidelines.
