Telepathy Inc. which is owned by Nat Cohen and owns a vast amount of premium domain names, has sold one of them and this time around it is Retirement.com!
The new owner is currently unknown, but it is very likely to be an end user on the corporate level. Whois records updated January 29, 2016 to the generic Matt Serlin / DNStination Inc. which is used by corporate brand protection and domain name registrar MarkMonitor.com.
Telepathy has had its hand in many six figure domain name sales and I see this one ranking up in the mid six figures and potentially even higher! High search volumes relating to the term with over 9 million in a broad search and over 150K exact match searches monthly.
