Competition in startups!
Entrepreneurs need to remember that the risk of failure has increased dramatically in the past few years.
Competition has become much tougher because starting a company has become so much easier, and everyone wants to become a founder-CEO because this is seen as being the cool thing to do!
In today's sharing economy, you can create a digital product on a Shoestring budget, using servers from Amazon; outsourcing engineering; buying ads on Google and Facebook, and getting your customers to do your marketing for you.
The competitive moat has become increasingly shallower, and this is why the success stories of the past, such as Amazon and Google are no longer applicable to the current crop of startups!
