hello aspirant,

Hope you are doing great. To start a business in the field of software, firstly select a technical course to which you are interested into like CSE, i.e., Computer Science and Engineering, ECE Electronics Computers and Engineering, etc., Later, enlighten yourself, and be confident about yourself. Prepare a project in the area, to which you are interested in setting up the business. Show your plan to the startup funding companies and after all the process, if they are interested in your business, they are going to fund, or else, if you had enough money, you yourself, can start the business, and shine yourself in the field.

Hope it helps !

Good luck, Thank you :)
