Here are some examples:
Contribune provides donor analytic software that allows an organization to track the news that its potential donors read. Users enter the URL of a news story that they care about, and Contribune facilitates donations to related nonprofits, tracks those donations, and elevates the story to the "front page" depending on the actions taken by readers. This seems similar to the services offered by Good2gether.
The Contribune site and blog include a movie that explains the process, but information on who is behind this site and what the revenue model is is somewhat vague (there are photos of the founder, but no last names listed). I presume that revenue (or predicted revenue) will come from selling data (donor analytics) to fundraisers (political and nonprofit) and from news sources. I suppose there could also be a token fee taken off of donations, but my guess is this won't be significant.
Giving is part of this model - but its really just the action that triggers the ratings that trigger the revenue. Sort of the way Nielsen ratings have been used to set broadcast advertising rates.
Contribune also launched a "charity focused URL shorteners - a technology that Twitter has made requisite. This URL shorteners allow you to clip a URL of any length into a shorter one, saving space in twitter and even allowing for some "built in" advertising. This is particularly true with the Giv.to shortener, as the clip will now look like "http://giv.to/cancerprevention" or "giv.to/savethewhales." These URL shorteners are loved for the brevity and vanity - they also provide great metrics as you can track who clicked through on the URL and what actions they took. Again, great data of potentially great value.
Last year we saw the development of search engines that enabled giving. Now we've got news sites and URL shorteners. What do you think will be the next technology action to integrate charitable giving? And what should we call this kind of embedded giving?
