Twitter Now Has 300 Employees

"Agreed. Pretty small team compared to their online footprint and buzz.

I assume that outsource some of their work to outside firms. Anyone know how much? I recall Pivotal Labs and East Agile did some dev work for them. "

lwsinclaireastagile.com should just work. Why do we need to use http:// prefixes in tweets? Ending in .com is enough.#assumeHTTP

After several weeks of initial development by Pivotal Labs in San Francisco, East Agile has provided some additional support and helped Laura Fitton's oneforty application during the transition to its own development team.

This is an example of how our client, Twitter, is changing the way news is reported around the world. Read about it on CNN.

Twitter became a client of ours this month.

Naturally, I am extremely proud of this association. I believe our quality and transparency oriented agile development process, and our reasonable rates were important factors in their choice. I think it also helps that we are quite compatible with the methodologies of Pivotal Labs, which has also worked very successfully with Twitter.
