The new service at www.boggleit.com offers exactly that. Set up by experienced entrepreneurs for, well, less experienced entrepreneurs, boGGle has pages and pages of advice on every step you need to take when turning your initial idea into a marketable and successful product.
For a tenner, you can run your idea through boGGle's "SNAPshot" test. This will force you to deal with the kind of questions that any serious venture capitalist will demand the answers to. Luckily though, it’s only a website. You have as much time as you want to come up with a good answer – or go away and fill in the gaping holes in your plan!
If your idea scores well enough on completion of the SNAPshot test, and you want to take it on more seriously, boGGle offers “BIGshot” – a chance to get in direct contact with the panel of real human investors and entrepreneurs behind the site. And if they agree that you’ve found a great idea for a startup business… you might just find yourself with a startup business for your great idea.
