The colored infinity symbol is not new actually and is used a lot.

Kayako, indeed a very respectable company is using it in their way, another one is the old MDSN logo, and I'm sure there's a fair bit of others.

Anyway, ours has a few special attributes which makes it unique - first, it resembles a group of people holding hands; second it is the OO part of the BOONEX company name; and it's very dynamic.

Anyway, the logo has been developed from ground up by a professional (and well-known) see more logo-designer using our ideas and suggestions. It has nothing to do with other logos and all similarities are accidental.
