A curator, gallerist and patron, Aparajita Jain is the founder of Terrain.art, the first blockchain-based art platform in India, and the co-director of the art gallery Nature Morte. 

She attended school in Kolkata and Mumbai before obtaining a bachelor’s degree in psychology from St. Xaviers College, Mumbai. Her grandmother was an art collector and this had an influence on her during her formative years. In 2005, Jain established Seven Art in Delhi, a gallery dedicated to showcasing new artists creating experimental works, exhibiting the works of artists such as Aakash Nihalani and Asim Waqif. 

The gallery held its first exhibition in 2006–07. Subsequently, Jain spearheaded over thirty exhibitions, including India Xianzai at the Museum of Contemporary Art (MoCA), Shanghai, in 2009, which was the first show of Indian contemporary art in China. In 2010, Jain founded the not-for-profit initiative Saat Saath Arts to encourage international collaborations and gain support for artists in India. The foundation, in collaboration with the government of Rajasthan established The Sculpture Park, at the Madhavendra Palace in the 18th-century Nahargarh Fort, Jaipur.

In 2012, Jain bought a majority stake in Nature Morte and became partner and co-director alongside founder Peter Nagy. Jain and her husband, Gaurav Jain, are also among the founding members of the South Asian Arts Council at the South Asia Institute of Harvard University. In 2020, Jain was inducted into the board of trustees of the International Sculpture Center, New Jersey. In 2021, she launched the blockchain-powered platform Terrain.art, which is premised on NFT-based ownership and patronage of artists and artworks. She is also a patron of the Kochi-Muziris Biennale. 

As of writing, she lives and works in New Delhi.
