Many people that I meet totally underestimate the time that this will take.
The reality is that 12 to 18 months is not unusual.
Yes, you will hear stories of start-ups that got funded in a matter of days or even hours; what they don't tell you is that it takes
12 to 18 months to become an overnight success!
After 5 years in the trenches helping people to find funds through Angels Den I have seen a number of proposals cross my desk and the entrepreneurs with the attitude that says "...this is the best thing ever..." or "...we are the next Facebook...." are usually doomed to fail.
