What type of business do i start?

Hello so iam thinking of buying a SaaS script but not sure what type of script do i buy like a ai image generator or what?

What are you interested in? Haven't you read Acres of Diamonds? Basically, instead of leaving your farm to look for the biggest diamond in the world, you farm the fertile soil under your feet for diamonds. There is plenty, I bet. How old are you, and how many subjects have you had an interest in? Don't just make another samey, samey SAAS. Build something with a unique angle that once people arrive on will definitely be back for more and share with their friends.
