Have a look at the DressRush investor presentation, an entire pitch deck written as a web site, in the public domain. Some of my observations.
I like publicly available investor pitches. It fits in the wave of increasing transparency in the startup funding market. (Check out Angel List). Startups can dramatically increase their access to potential investors by making part of their content public. The first stage of a fund raising round does not have to be the closed meeting room of the VCs that happen to be located in the same city as you are. Obviously you would not put your core IP, financials, or other sensitive strategic content in a public presentation. Another option would be to make the sensitive part of your investor pitch on your web site pass word protected.
I like these airy web sites. Lots of white space and information that you can scroll through freely, up and down. I actually first skim the whole site in a few seconds, then go back up to start reading in more detail. This is so much better than the nervous clicking on a small button in a SlideShare window (especially when people design slides that -click- break up -click- a sentence -click- in 5 -click- slides.
It is still tricky to design from this new medium though. The DressRush example uses beautiful muted colors (interrupted here and there by images and facebook logos) and takes an infographic approach to investor pitches. On certain pages it works, on others it does not. In whatever direction the technology develops, you still will need to eye of a good designer to get your investor pitch right, also in HTML.
I will continue to follow these developments with interest.
