I like the page, very clean and tells me what you're trying to solve. The video was a nice intro and looked very professional; I really like when product landing pages have a video as it really embraces the "don't make me think" paradigm. My only nitpick is with "pick & pack." Is that an industry phrase? If so, I'd capitalize it: "Inventory, Pick & Pack, and Ship without the hassle or the cost. Otherwise, I'd just say "pack" as the "pick & pack" thing made me thing there were multiple products, one for Inventory and another for Pick & Pack.

Just out of curiousity, how many guys are working on this app? It looks fairly polished for just entering alpha.
