Twitter operated out of a Boulder office on Walnut St. for years, mostly housing the employees of Gnip, a company that sold Twitter data to enterprise customers which Twitter had acquired.
The Walnut office consisted of the top two floors, 3 and 4.
Slowly the office morphed from being "Gnip" to being a genuine Twitter office, with folks from all kinds of teams working out of the office including Timelines, DMs, Trust&Safety, and Tweets. Most of the teams were geo-distributed.
It grew fast.
