The AY Foundation, Inc. (AYF) traces its roots to the Bayanihan Foundation set up in 1970 by Amb. Alfonso T. Yuchengco to administer an educational fund for the children of Grepalife employees
and sales associates.  But the foundation’s scholarship program later expanded to include street children and members of the indigenous groups.  Likewise, grants for professorial chairs
and school building assistance were also extended by the foundation to selected educational institutions.

In 1983, the Bayanihan Foundation was renamed A Wise Foundation.  In the
same year, a partnership with the Manila Jaycees was launched to co-sponsor the Blessed Teresa of Calcutta Award (formerly known as the Mother Teresa Award).

In 1986, the foundation started to support health related projects. It provides financial assistance to support the conduct of out-of-town surgical/medical missions. It was in 1999 when the foundation took a more aggressive role in medical and surgical missions by actually organizing them as it expands its network of partners to include the University of Perpetual Help Rizal Medical Center of Las Piñas and Biñan.  At present, the foundation has a various network of volunteer medical specialists from respectable hospitals/organizations, which include the Our Lady of Lourdes Hospital, East Avenue Medical Center, The Medical City, Makati Medical Center, Muntinlupa Medical Center, Ospital ng Sampaloc, University of Sto. Tomas Hospital, St. Louis Hospital in Baguio, Sta. Ana Hospital, St. Luke’s Hospital, and the Philippine College of Surgeons.

In 1988, the foundation changed its name again, this time to AY Foundation, Inc.  Two years later, the AYF National Discipline Awards was launched.  The awards are conferred to outstanding high school graduates who best exemplify the virtues of discipline, integrity, self-sacrifice and courage.

In 2001, the CYCLE (Championing the Youth for Community LEadership) training program is launched to instill social responsibility among the National Discipline awardees.

Through the years, the foundation’s health promotion and advocacy programs continue to expand.  The foundation provided financial support for twelve years for the operation of a clinic for the urban poor situated along the Manila-Cavite Coastal Road, which later on became a hospital.  The foundation also built a health clinic in Paglat, Maguindanao in 2006 to provide quality medical services for the indigent patients in Mindanao.  And in 2010, the foundation started to work with the Philippine Christian Foundation to provide assistance for the operation of a clinic in Tondo, Manila.
