Doorstep delivery has been one of the biggest disruptors of the new age economy. From getting groceries delivered to your doorstep, hailing a cab, getting meals delivery, all you need to do is swipe on an app and the item would be made available very quickly. This is the basic idea that resulted in Repos Energy, a Pune-based startup that is using tech tools to deliver diesel from pumps to office complexes and businesses directly. The two-year startup co-founded by Chetan and Aditi Walunj combines technology with logistics to offer solutions in the B2B space.
