Don't Start A Startup Alone?

Don't Start A Startup Alone?

This has been said over and over again. How much it is true? They say you require shoulder to cry. You require another head to think. You require another soul to console. Etc..

I heard this again at last week's NSSCOM product conclave.
I feel "For every theory that exists, there is a equal and opposite theory”.

Is There Any Successful Product Startup Started By One Person?

I know few in US. Let me know your comments!
