This is exactly why this product doesn't exist yet - I looked at building this exact app 18 months ago.

Yelp expressly forbids this, and without Yelp, you don't have a product. That said, I think it's stupid that Yelp disallows this and hope that OP succeeds.

I've had numerous discussions with folks about projects that all involve LinkedIn data. People always seem to assume they're the first people to have idea X. After digging in about 18 months ago, I saw how limiting the LinkedIn API was, and that basically none of the functionality people wanted to do was possible. technically possible? yes, for a while. Legally? It's outside their terms of use, and you'd either get shut down or sued.

I know of at least one other Chicago startup (no affiliation) that's been doing this exact thing for a year or two. I'll refrain from name dropping them in OP's announcement thread, but I did notice that any mentions of Yelp fell off their site a while back which leads me to believe Yelp may have come knocking.
