Competitor Analysts for night clubs/bars promotion services

We need market research performed to find all the possible competitors to the following idea: Any website or mobile app that is used to help promote night clubs and bars. Kinda like Groupon for night clubs and bars. From the user perspective, I install mobile app and could see is there some nice promotion in clubs/bars near me. What is the perfect competitor's use case? Clubs/bars can register on the website, pay a little fee and announce their promotion (50% of the bottle, free admission for 2, free drink, etc.), regular user can check via mobile app (or via website) what clubs/bars have promoting (of course in their neighborhood). What is expected from you? 1. You will be given google form link where you would enter details about each competitor 2. Each competitor is divided into three types; first - the ones that are helping clubs/bars promotion in any way. second - the others who perfectly match the use case mentioned above; third - only the ones with mobile app that promote clubs/bars events 3. We need at least 10 of each competitor type. 4. All competitors should come from US primarily but any competitor from English speaking country is valid one.
