In 1998, Ramji left his commercial career in banking and finance to create
Agastya International Foundation, to provide science, math, art and design thinking education to over 30 million underprivileged children and 250,000 government school teachers across India. During his tenure, Agastya has pioneered many educational innovations at scale, including mobile science labs, lab-on-a-bike and peer-to-peer learning via mega science fairs for
underprivileged children. Agastya's 172-acre campus creativity lab houses over fifteen experiential science, art and innovation centers, including the
Ramanujan Math Park. In the late 1980s, Ramji met
Janaki Ammal, wife of the mathematician,
Srinivasa Ramanujan in
Triplicane, Madras. In a blog appearing in a TIFR journal, Ramji mentions Mrs. Ramanujan telling him, "no one remembers my husband anymore". More than a decade later, a bust of Ramanujan was installed in the Agastya campus creativity lab. Agastya gifted identical busts to the Institute of Mathematical Sciences,
Cambridge University, the
Indian Institute of Science, Bangalore,
TIFR’s Institute of Applicable Mathematics, Bangalore, the
Indian Institute of Technology, Madras,
MIT, and Stanford, USA. His daughter, Jeena Raghavan's painting of math genius Ramanujan, was purchased by Devesh Mody of Texas and gifted to Stanford. With support from the government of Andhra Pradesh, Ramji and his colleagues established a 172-acre campus creativity lab near Bangalore. In 2007 Agastya signed a MoU with stock market investor
Rakesh Jhunjhunwala, which helped Agastya to scale its outreach activity and build its creative campus. In 2010 the Government of Karnataka signed a MoU with Agastya International Foundation to establish an ecosystem for hands-on science education in the state. Wisdom of Agastya, an illustrated book authored by Vasant Nayak and Shay Taylor of the MurthyNayak Foundation in Baltimore, USA, chronicles Ramji and his team's journey between 1999 and 2014 in building Agastya International Foundation. In March 2021 Agastya announced the creation of Navam Innovation Foundation in partnership with the Pravaha Foundation of
Hyderabad. ==Recognitions==
