DomainMarket.com owner and successful domain investor Mike Mann has confirmed another domain sale: the $22,500 sale of IndustrialHeat.com - a domain name he bought three years ago for just $60. As of publishing, the WhoIs hasn't been updated to the new buyer's details, but from some Google research, I think the buyer could be Industrial Heat LLC - a North Carolina based energy company created in 2012 with a $12m in funding round from Cherokee Investment Partners. This is an excellent 374x ROI for Mike Mann in just 3 years of ownership, and goes to show other investors that there are still opportunities to make a lot of money with domain names, it's just a question of finding the right domains. Just last week, Mike Berkens announced a $50,000 flip on a domain name he bought for $1,111 just 60 days before. Also confirmed today was another Mike Mann sale - Fun.co for $70,000.
