Why is there a log in button at the top right but not a sign up? I know with the google auth thing it's the same, but as a user you don't know it.

Perhaps make an entire "contact" page, I dislike mailto: links. It opens my company's preferred Email client called IBM Notes and it sucks.

Once you have your MVP, please add transitions/animations. The site is too instant so to say, when clicking a button you expect some small delay. Even if you pre-loaded this, it's sort of important.
