Ok the idea is fine/promising but you'll need to provide more information if you have any hope of raising 5M or anything even close to that.
Your Facebook/Twitter/Blog all look like ghost towns with no user interaction/responses whatsoever. A little weird.
Hi! I'm Aliya Salakhova - one of Doft founders. You can check me on LinkedIn, I really exist.

Please, ask any questions you want. What is the exact information you'd like to get?
Concerning social network pages, they basically play the role of informative sources about our company highlights and freight news. The market we deal with is quite conservative - there are old-school brokers, shippers and truckers who spend countless hours on the phone or just drive long distances. It's not usual for them to be involved into discussions and comments in social networks like us. You can always google Doft and read publications on major blogs.
