Few more thoughts on the same lane<p>Advantage for such a platform:
1) Atleast for restaurent business, this model makes sense as nobody goes to the same restaurent every day. Buy keeping him in a closed partner network, you are enhancing the chance to get him back again.<p>2) This will also encourage customers to go out and try new places<p>3) This will work out great for new business<p>4) some extra revenue for more established players.<p>Challenges : Identifying complementing business is going to be a big pain. Also the revenue sharing is going to be a pain too.<p>Other thoughts: We could manage all the coupons and deals online so no business will feel the extra pain. We could make the consumer scans the bill using a app and that could be used to get deals/coupons. Soo many ways we could implement it to make it painless.<p>Another thing is that, it will change the way we look at a business. Rather than one single entity, over a period of time, we will have a partner group of business we trust. So having a good partner will help your business and a wrong one can impact in a bad way too.
