Content and Social Media Marketer. Currently run a news/humor website with over 1 Million Pageviews a Month. New startup consultant and Fortune 500 Clients
I've consulted and worked with fortune 500 companies to brand new tech startups. I'm a graduate of The Foundry based out of the University of Utah and I have my MBA. I can show you the mistakes that many startups run into as they start growing.
I run a blog that currently receives over a million pageviews a month. I only started the blog a year and half ago. I've taught courses and spoken to numerous large groups as to how to grow your blog quickly utilizing a startup mentality.
If the mere mention of your idea/product is all it takes to rip you off, you're already screwed.
There has to be something else that differentiates your company other than simply the service/product you are offering. This can be a whole laundry list of items but ultimately, there has to be something other than simply the idea to sustain your business, otherwise you're going to lose.
In my mind, entrepreneurs are too paranoid w/ other business stealing their ideas. Don't worry about them stealing it, worry about when they stop.
