Ask HN: List of great web development shops

I'm interested in compiling a list of web development shops that tend to

* build high-quality medium-complexity websites using the best open-source frameworks and tools

* have at most a couple dozen employees, and most of them are technical

* have egalitarian decision-making structures

* probably have a physical presence

I started a spreadsheet with four that I happen to know of: http://exoweb.net (Beijing), http://hashrocket.com (Jacksonville, FL/Chicago), http://bocoup.com (Boston), and http://unspace.ca (Toronto).
