I feel the landing page needs a minimum example of how to get value, not only how to install it. Think stripe, that to this day shows how to integrate it with a few lines of code. When looking at the tutorial, I also feel a lot of steps necessary to check it out. Why not provide basic functionality out of the box or a quick start to git clone?
On another note, having built startup search myself [1], I think the demo does not do the technology justice [2]. People will most likely judge the product based on it, but the offered startup search does not work as expected, e.g. when trying "food delivery". Feel free to get in touch, will happily provide some data :)
