Online grocer BigBasket is on an expansion spree. With the acquisition of Morning Cart and RainCan, it has got into new segments — microdelivery and physical/omnichannel commerce. The e-grocer has also acquired a controlling stake in kwik24, which operates cloud connected, unmanned vending machines.
