Disclaimer : I have been a founder of a failed startup Patterbuzz. And this blog of mine used to be a full fledge company about 9 months ago. Now, I head the Product Management of a well funded startup.
Why the Disclaimer first ? for a simple reason that I have been through the journey of a startup, running it successfully for more than 2 years, raising seed money, getting traction and then, shutting down for inability to raise next larger round of funding.
