I think I get the idea of the product, but with the information you have provided - I can never be 100% sure.

First, I would suggest adding a demo video on the front page. If you like your page to have as little content as possible - that's fine, but unless you add something small that tells a lot (like a video), I suggest many people will just give up very early on.

Second, the "used by" section. I think that if you manage to get testimonials from individuals, it will look better and feel more personal.

"SYNCED PRESENTATIONS TO ALL DEVICES" - I don't get why this is formatted this way? I'd put it in the center with another smaller sentence underneath that briefly summarises the product.

I think what you offer is pretty neat (if I have managed to understand it correctly) but I feel you should do a bit more work re: selling it better.
