The following video will give you an investor’s insight on the importance of calculating your total market size correctly… one difference between local and startups from US and Europe notably is that the latter tend to think too big (as addressed by the investor in the video) while local startups tend to think too small… find that balance: dream as big as you can, but have the data to back your ideas up…

(After 10 minutes the video becomes too much of an advertorial, but before that it should give you a great insight into the investor’s mind.)
