Nandi was a trader who traded in cotton, salt, and silk. Nandi met Warren Hastings in 1750 when they were supposedly of the same age. He saved Hastings life when he was imprisoned by the Nawab of Bengal
Siraj ud-Daulah by helping him escape prison. From 1754 to 1756, he served as a banian to Warren Hastings. While Gokul Ghoshal went after properties in sparsely populated areas Nandi preferred densely populated areas such as
Murshidabad. Nandi expanded further through buying estates under the
Permanent Settlement in Bengal. Hastings seized the estate of
Rani Bhabani and handed it over to Nandi. He built the Kasimbazer Rajbari which had marbles from Baneras. The marbles were gained by Hastings in his expedition against
Maharaja Chait Singh in which Nandi accompanied him. == Death ==
