I wish you success in obtaining investor lists
But there is a point that must be taken in your mind
that you must search for customers or investors who need your service or product, because it is possible to find a list of a thousand investors, but no one is interested in your service or product
Therefore, you should research the scope of your product or service
You can contact me to explain more......

A great place to start would be angellist.com. LinkedIn would be another good resource for finding investors and VCs.
