Thanks for the constructive criticism. I'll try to tone it down a bit in the real site. I just did the teaser site quite quickly to collect emails, before a conference I was talking at.
Sure, glad if I helped. To complete my suggestion—you can also change landing page layout to make logo more prominent (something like http://docker.io/), in which case it doesn't need to be simplified.
It especially concerns the application section of Predictobot: current logo will be too distracting.
Compare a few pages with similar layout to yours, note they all use more schematic logos that draw less attention to header: https://www.getsentry.com/, http://www.fiftythree.com/paper, even http://insideintercom.io/
http://www.docker.io/ is interesting: their logo looks good in ‘hero unit’ as it has the detail, and at the same time not bad in header because of more or less simple shape and not much contrast. (For favicon they've simplified it somewhat.)
