I mentioned Crunchbase maps since that was the first site that I was aware of that did this kind of thing. It is certainly possible to do it better. >This is only for San Francisco. I just linked to the SF map (notice the URL); maps exist for other areas, too. >Crunchbase on the other hand, appears to have limited functionality and is sparsely populated. Functionality-wise, the sites are pretty similar except Crunchbase maps doesn't list jobs (location-based job search engines do exist, though) and to alter information you need to go to another part of the site. Crunchbase maps obviously looks aged and doesn't even include all data points on the same map so this site is better in that regard. However, if you include the non-SF maps Crunchbase maps has much more data than this does (at least right now and some of that data may be outdated.) They also offer a RESTful API and might (not sure) allow you lots of flexibility for using that data (worth looking into at least).
