You've probably thought of this & just haven't got around to it yet, but you might want to localize the screenshots on the English & Spanish pages, not just the text. Though it's also really cool to see a French startup.

The page headline should probably be "Simplify video project management", ie drop the 's' in projects. "Projects management" sounds awkward to me.

That front page image/cartoon is awesome. It makes me want to signup regardless of what it is!
