Jay Westerdal (born 1978) is a domainer and entrepreneur, best known for his work creating DomainTools.com, a web service that looks up historical ownership of a website. The whois service was integrated into Google's onebox in May 2008.[1] He later sold the company in 2008 for a reported $16–$18 million.[citation needed] He is a technology blogger.[2]


Westerdal started Name Intelligence/DomainTools in 2002 in his parent's garage. In May 2005, Jay started the domain conference "Domain RoundTable".[3] He later sold DomainTools in 2008 to Thought Convergence, Inc. The following year, after being acquired, he left TCI.
