This feels like an overly strong assertion based on one piece of anecdotal data. Saying that you played with this and got good results in one case is different than saying you've done experiments for multiple different startup marketing pages and consistently those pages without a logo at the top perform better.

Google is one of the most intensive A/B testers in the technology space, and on every logged out page of Gmail and Google Drive and Google Calendar, guess where the logo is?

Edit: I would add though that the argument around communicating the "Why" is more important off the bat than the "who". That said, having a minimalistic logo in the top right or left won't likely distract them for very long - unless there's evidence of that?
