I've worked before with my two startups with teams from India, and this was a disaster, but I think the reasons why were:
#1 Lack of my experience in dev area - how to work with dev teams (mainly external)
#2 Pricing - I was price sensitive, and in the long term, it caused that the code was not usable while scaling the business.
I hated it so much that after those two startups I've built my own software dev company focused on one technology and a quite small team of tech-savvy colleagues.
