There have been a bunch of attempts. I think that one might eventually succeed. The problem is the difficulty in actually figuring out who's advice is worth what & where. But, in many cases 30 minutes with the right person could be incredibly valuable. Technical/scientific/engineering expertise is one are, industry knowledge is another one. I think the second might be the most important. Say you have some sort of awesome technology that you want to market to the hotel industry. You need to understand how that industry works. What software they use & how. What they pay for various things. The right person could get you months ahead in 30 minutes.
