• Jack Sim, Founder of World Toilet Organization
(WTO), has been a successful businessman since

his life according to the motto “Live a useful life”.

journey that saw him being the voice for those
who cannot speak out and fighting for the dignity,
rights and health for the vulnerable and poor
worldwide.
3. Bill and Melinda Gates
• Guided by the belief that every life has equal value, the
Bill & Melinda Gates Foundation works to help all
people lead healthy, productive lives. In developing
countries, it focuses on improving people’s health and
giving them the chance to lift themselves out of hunger
and extreme poverty. In the United States, it seeks to
ensure that all people—especially those with the
fewest resources—have access to the opportunities
they need to succeed in school and life. Based in
Seattle, Washington, the foundation is led by CEO Dr.
Susan Desmond-Hellmann and Co-chair William H.
Gates Sr., under the direction of Bill and Melinda Gates
and Warren Buffett.

• History: In 1998, Jack established the Restroom Association of Singapore
(RAS) whose mission was to raise the standards of public toilets in
Singapore and around the world. As Jack began his work in Singapore, he
realized there were other existing toilet associations operating in other
countries. However, there were no channels available to bring these
organizations together. As a result, on 19 November 2001, Jack founded
the World Toilet Organization (WTO) to bring these organizations together
to share information resources and facilitate change.
• Impact: The World Toilet organization pioneered the creation of Sanishop-
a social enterprise that improves sanitation conditions globally by
empowering local enterprises. In India and Cambodia, farmers have access
to low-cost and affordable toilets. As a result, households reduce their
medical expenses as they do not fall sick as often and this increases their
savings. Since 2009, SaniShop Cambodia has built 11,211 household
latrines and trained over 500 Sales entrepreneurs in 7 provinces.
5. Bill and Melinda Gates
• History : It all started when Bill and Melinda read an article about millions
of children in poor countries who died from diseases eliminated long ago
in the U.S. Bill and Melinda Gates felt that they could do something about
it and flew all the way to India for the foundation administering oral polio
vaccines to kids. In 2000, the William H. Gates Foundation merges with
the Gates Learning Foundation to form the Bill and Melinda Gates
Foundation led by CEO Patty Stonesifer.
• Impact: More than 100 million children are immunized each year against
tuberculosis, polio, measles, diphtheria, tetanus, pertussis, hepatitis B,
Haemophilus influenzae type B, and, in some countries, yellow fever.
These vaccines save an estimated 2.5 million lives each year. The global
incidence of HIV has declined by nearly 40 percent since 2001, and 17
million people worldwide are receiving antiretroviral treatment.
