Ask HN: Question on copyright/trademark

Hello HN -

I am in the process of building a startup and have a question regarding the name. The website I have chosen uses the .me TLD, and I intend for that to be part of the name. For example, say my site is Foo.me

Another larger company exists and has Foo.com, and There is a copyright for the Foo product - however, from what I understand names must be trademarked and are not copyrighted. My product is NOT a copy of Foo product, and I intend the product to be known as "Foo.me" . I cannot find any listing in the trademark database for "Foo". Am I safe in assuming my product name is safe from any infringement on Foo.com's name and/or product?
