I wouldn't say this is too much work actually. It's beautifully designed and coded but a decent designer/coder duo can probably finish this in a week, iterations can happen after.

I believe they must have some sort of a Keynote presentation that is evolving constantly, to show in meetings or so. This thing is for showing off maybe.

My personal opinion is heck yeah it's worth it! I mean, even if it turns out to be not such a good idea for startups to consider, it's innovative if they have some good plans for growing -I believe they do considering that the founder is already in this field (vizualize.me)- it would be like creating some sort of a startups meme.
