Mike Mann has a long and successful history within the domain name industry. As the founder of BuyDomains.com, Mike created the second largest market for domain names at the time and successfully exited the company in 2005. Now, @Mike Mann heads up DomainMarket.com and boasts a portfolio of several hundred thousand domain names. Mike regularly posts sales data via his Twitter account and has amassed some impressive five and six-figure sales. Here, we take a look at Mike's top ten sales of all time from his DomainMarket.com portfolio, according to data from NameBio. 1. CryptoWorld.com The largest publicly disclosed sale from DomainMarket.com is that of CryptoWorld.com. The sale closed in January 2018 for $195,000 and the buyer was revealed as Binance, a cryptocurrency asset exchange. Six months after the sale was announced, Binance has failed to do anything with the name, with CryptoWorld.com currently displaying an error page. 2. Favorites.com Our second sale on the list is Favorites.com for $165,000. This deal took place in mid-2011 and was quickly developed by an Oklahoma based company called MyResource. The site is still running, although the traffic looks to have declined significantly, according to Alexa. Interestingly, the company also purchased Favourites.com. According to NameBio, the sales price was just $5,100. 3. Business.co The eighth highest .CO sale of all time, according to NameBio, is Mike's sale of Business.co in 2011. The name looks to have been acquired by a European domain investor based on the last available WHOIS records. Various archival copies of the domain indicate that the name has been parked at Sedo since the $80,000 purchase in 2011. 4. RiseUp.org In March 2017, Mike announced the sale of RiseUp.org via his Twitter account. According to Mike, he purchased the domain for $350 in 2005 before selling it twelve years later for $75,000. Although the name sold in March 2017, the WHOIS data still showed Mike's company as the owner in September 2017. By early 2018, the name was put under privacy protection and the domain currently doesn't resolve, so it's difficult to ascertain who the owner is. 5. BroadSpectrum.com BroadSpectrum.com is a domain that is certainly being used. Australian infrastructure company Transfield Services rebranded to "Broadspectrum" in October 2015, buying the BroadSpectrum.com domain name for $75,000 in the process. The domain was quickly developed and still holds the company's homepage. 6. BetterFuture.com One of Mike's most recent sales is that of BetterFuture.com for $65,000, which closed in April 2018. This two-word name was acquired by a company called Better Future who offer free background checks. The company upgraded from GetBetterFuture.com and currently hosts the company's homepage. 7. TotalDesign.com Another sale that occurred in April 2018 was another two-word .COM, TotalDesign.com. Mike's company acquired this name in 2007 for $5,200 with the sale coming eleven years later for $60,000. The buyer was a Dutch design agency that rebranded from Total Identity to Total Design. The domain now hosts the company's homepage. 8. SkyBoard.com Another $60,000 sale from Mike Mann occurred in 2012 when his company sold SkyBoard.com. The original acquisition price was less than $2,500 in 2007, representing an impressive return on investment within five years. The domain is now home to a French service called Skyboard who offer unique meeting venues for company executives and their clients. 9. UpperPeninsula.com The penultimate sale on our list sees a fourteen-character name sell for $55,000. The name, which sold in 2012, looks to have been acquired by a Michigan-based individual. The name is forwarding to theUP.com, but the site no longer responds. According to archival copies of theUP.com, the website offered products and gifts from Michigan's Upper Peninsula. 10. Offset.com The Offset.com domain is another name from DomainMarket that sold in 2012. This name was acquired by stock photography giant Shutterstock's Offset brand for a price of $50,000. Offset launched in 2013 and was designed to offer royalty-free photography for commercial and editorial use. Five years later, the service looks to still be a popular destination for premium stock photography.
