The only management names I found were
Felix Arburola who has been a minion in the Costa Rica sportsbook sector for years and the "co-founder and general manager" James Hampelton, who sounds pretty Brit.
I have found cointelegraph's article dated in 2014. but couldn't find any info about him.
There are 3 accounts in nitrogen's linkedin
https://www.linkedin.com/company/nitrogen-sports/about/ but I don't see important position - chat moderator, support and one is some kind of security dude who seems work for one consulting or security company in U.S, but website is not online so probably it is not worth mention it.
Someone in this thread mentioned Ideal Media Inc and there are many affiliate sites mentioning that company, for example this one
https://www.bitcoinsportsbooks.com/reviews/nitrogen-sports/The company is located in San Juan, Costa Rica and is owned by Ideal Media Incorporated.
Linking to this website:
https://idealmedia.com but according to linkedin that company is in Manhattan
https://www.linkedin.com/company/ideal-media-inc/about/Maybe wrong link on affiliate site.
Company is also mentioned in this site
https://www.vip-bet.com/bitcoin-betting-sites/nitrogen-sports-review/ The company behind Nitrogen Sports is located in San Pedro, Costa Rica and all of their support staff and servers are situated in Costa Rica as well. The parent company is Ideal Media Inc, which is also located in Costa Rica.
And there is link to linkedin:
https://www.linkedin.com/company-beta/3293788/?pathWildcard=3293788 but it is broken.
This also didn't give anything:
Huh. Should this be in investigation? I mean, all this info is from shill sites except picture which doesn't reveal anything except some random companies.
