I am thinking of establishing software development team in Nepal as the investment is relatively inexpensive than other countries. But i don't know, how can i get such company who invests for my engineering team who will deliver the products for the company?
You can speak to local communities and business hubs
Your question seem unclear here. You need someone to invest some funds into your company? Or you need someone to help take your products to the market? Like a marketing pro?
Your team need to deliver a few simple products to show what they are able to do. You could represent it as product samples.
Investors like to see MVPs, so show them
