Don't just pick the easiest path — it's worth thinking about your long-term goals first. Generally, choose a Private Limited company if you want investors, or an LLP if you prefer lower compliance and fewer headaches.
Once you decide, you'll need to get your documents (like DIN and DSC) in order and file with the MCA. It’s a bit of a process, so I suggest you grab a CA to help you handle the MOA/AOA or LLP agreement. It's better to get the foundation right now than to have to change it all later.
