From New York Times:
Many venture capital firms are loath to finance mash-ups, in part because they are not readily “defensible,” meaning they might be replicated by others.
“The current things people are doing with Google Maps are cute but they don’t add value,” said Peter Rip, managing director of Leapfrog Ventures in Menlo Park, Calif.
Web mash-ups, which have proliferated in recent months, can be made up of two or more sets of data. They are often based on Google Maps or Google Earth, then overlaid, or tagged, with information on the location of just about anything.
I don’t know the first thing about venture capital, but I do know enough about business to refute Mr. Rip’s commentary. If I visit a mashup like Platial to find a list of taco stands in San Diego, or a place to refuel my biodiesel car, that is indeed valuable in the marketplace sense.
