Harshil Mathur, Shashank Kumar, 

Indian Institute of Technology, Roorkee alumni Mathur and Kumar have had their hands full keeping up with demand. Their troika of offerings—payments, neo-banking, and lending—have enjoyed rapid growth during the pandemic. The six-year-old startup raised $100 million in October at a $1-billion valuation. Payments volumes had tripled, the newly minted unicorn said in February, as did its valuation in April when it raised another $160 million. Funds that Mathur and Kumar, ex-engineers at Schlumberger and Microsoft, respectively, will use to add new products to their lending and neo-banking platforms.
