BharatPe co-founder Ashneer Grover has resigned as managing director and board director, the Indian payment startup said on Tuesday, in the wake of a public row with Kotak Mahindra Bank over his personal investments. BharatPe has come under intense investor and media scrutiny since Grover sought damages from bank boss Uday Kotak, alleging Kotak Mahindra Bank declined financing for a personal investment.
