Seventeen individuals and families have joined the Giving Pledge since June 2015, bringing the current total of signatories to 154 from 16 countries.

The Giving Pledge, a multigenerational, global initiative created by Warren Buffett and Bill and Melinda Gates, encourages billionaires to give the majority of their wealth to philanthropic causes.

“This new group joining the Giving Pledge is incredibly thoughtful about their desire to give back and help solve the world’s toughest challenges through philanthropy,” Bill Gates said in a statement.

“Some have been giving for decades and others are just starting out after building successful businesses, but they all see the value of giving in a bold and effective way. Melinda, Warren and I are glad to have the opportunity to learn with them and from them.”

The new signatories include entrepreneurs and business leaders from diverse backgrounds and sectors, including technology, medicine and biotech, real estate and dairy farming. They support a range of causes, including poverty alleviation, health care, education and environmental protection.

Following are brief profiles of the individuals and families who have joined the growing list of pledgers:
