Back in 1997, David Kammerer registered the domain name 4001.com as a joke after saying the phrase “I have 4000 and one things to do today”. The name became a hobby site for David who used his domain as a base for guitar tabs for Irish guitarist and songwriter Rory Gallagher. This resulted in thousands of visits to his website and related videos, years before YouTube had been created. Domain investors will know that the domain 4001.com holds value as a four-number .COM domain name, but David was unaware of this until June 2016. David told me: “I discovered the value of 4001.com all by accident last June 2016 as I never checked the whois only email address.” In the email address listed on the domain’s WHOIS details were over three hundred unsolicited offers and inquiries. David chose not to sell the domain at the time but looked into why a domain name may have received such interest. After searching through Google, David found Andrew Alleman’s (@DomainNameWire) podcast and the NamePros forum, where he found out more about domain name investing and China’s interest in numeric domains. Still owning the domain, David pondered its future whilst travelling between August and December 2016. On his return, he decided to sell the name that he registered way back in 1997. For the first time, we can reveal that 4001.com sold in April 2017 for $23,000 to a Chinese domain name investor. Since then, David has started to learn more about domain name investing and has reinvested some of his earnings back into three-character, four-character and brandable domain names. We hope that after David's first ever domain sale, his subsequent investments will prove to be as successful.
