I want to build a start-up in India. What idea could be the next multi-billion dollar idea by 2017 or 2018?
Taking the question at face value.. here are some of my ideas for a multi-billion dollar business potential in the next few years.. Some ideas may seem whacky or just plain stupid (due to my limited knowledge), but please feel free to add your comments.1. A money lending institution that charges lesser % interest than guideline base rate. 2. An app that would revoke an email after it is read by the recipient - removes traces of the mail being sent at all3. Mobile battery juice packs under $10 for emergency usage.. maybe you could make it last for just one or few phone calls, I don't know... just solve this problem! should be something really small that fits in your pocket4. Start your own internet that kicks ass.. charge everybody $1 one-time fee to join in5. a mobile phone with in-built cigarette lighter ;-)6. Real time tracking of all commercial planes, trains, automobiles7. Real time monitoring of all micro organisms in the world 8. A cheap way to make you forget a book or a movie so you can read or watch again with the same thrill of doing it for the first time9. Find a way to store and tap energy more efficiently10. A device that uses the pressure your shoe soles to convert it to electricity and store it in a battery.. so you can recharge your mobile device from your shoesinteresting to come up with such ideas.... will come back and add more later.
