Blume Ventures

The Mumbai-born seed and Series A firm that started in 2010 with a ~₹100 crore domestic fund when India had almost no institutional seed capital. It grew into one of the country's most consistent early-stage franchises (TaxiForSure, Unacademy, Slice, Spinny, Purplle, GreyOrange), and its unusually open writing on fund economics and the "Indus Valley" market made it a public voice on what Indian venture can actually return.
