Welcome to the Q&A Forum

You just confirmed everything I suspected. Thank you!

Thanks, Patrick! Best wishes for an excellent 2015 to you, too!

Sounds good! Keep us updated with how it goes. -Andy

Agree with the others here, two or three sites definitely are a lot harder to maintain, and a properly-structured website can cater to different types of audiences, even when they vary a lot. You'll want to be very careful with the UX and perhaps work with some conversion rate optimisation people as well to segregate the audiences and not confuse the sales process for either, but this should be possible, especially if you focus your marketing for each audience to drive traffic to pages where there is no initial cross-over (shared navigation, etc.). I am guessing since I have not seen either product or preliminary site (if there is one), but I believe that one site would be better given that there will be shared pages, such as company information. If you were to create two sites, I suggest canonicalising the duplicate content to one version of the site, most likely the one with the larger user base or higher potential return. E.g., www.site.com/company-information and www.b2bsite.com/company-information are canonicalised to www.site.com/company-information if www.site.com is the primary business interest.
