Dear Student ,

As you are asking about startups, so I would suggest you first to gain knowledge in this field more deeply. in IT field , always B.Tech degree is not mandatory , all you just need to explore your preferred zone by job experience , some hands on experience .

For now. I will suggest you to focus on your study and choose any UG degree apart from B,TECH as you've told, you don't like that degree .

In startup case, Skill and knowledge on there required domain is most necessary than any specific degree .

you can refer to this article below to know more about Entrepreneurship :
