I disagree with everyone else!

The silos are good, you just need to make it much more obvious that the user needs to select one of the silos in order to get at more information. It's not particularly obvious that your buttons are buttons. I would also recommend that the content be full height / width so that on desktop at least the user doesn't scroll at all. The stock photo is probably unnecessary for the main page. Also you don't really need left/right margins since there isn't really text on the page, and that's what large margins are good for (but I'm assuming you know that since you made this app!)
