Twitter, Inc. is an American company providing social networking and microblogging service. Twitter was launched in March 2006 by its founders, Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams. The company went public in 2013, raising US$1.8 billion at US$26 per share. Twitter allows registered users to read, post, and interact with 280-character messages known as Tweets. Twitter values itself as a fast, unfiltered distribution of information. At the end of 2021, Twitter boasts 217 million registered users, almost doubling from five years earlier (110 million users). Twitter's revenue in 2021 was USD 5.08 Billion, 89% generated from advertising, with the remaining revenue primarily from licensing.

Twitter's organizational structure has undergone several changes over the past few years. The first of the big changes come about in 2018, when Jack Dorsey, then Twitter CEO, announced the creation of a functional organization structure. The functional structure grouped Twitter's employees based on their functional specializations and skill sets. At the time, Dorsey said he wanted to simplify the way the organization works. However, based on the type of business Twitter is, where there are many cross-division projects, employees often reported to managers outside of their product team. This can slow the decision-making process and make communication and knowledge sharing more difficult.

Dorsey often emphasized the need for greater discipline, which coincided with the hiring of Dantley Davis, VP of design, in early 2019, who focused on performance culture. Soon after he was hired, Dantley Davis gathered his senior staff in the room and said Twitter was too nice and was there to change it. It was reported that Twitter had long been very slow to build products, blaming Twitter's collaborative environment for making workers reluctant to criticize one another and call others out for lousy work practices. This is where Dantley Davis thought he could change the culture and see the organization produce better results.

In 2021, following the hiring of Parag Agrawal as CEO, Twitter underwent another major organizational restructuring, firing Dantley Davis, abandoning the functional structure, and adapting a divisional structure divided into the following segments: Consumer, Revenue, and Core Technology. Each division had its own General Manager and led engineering, product management, design, and research teams. The move was made to speed up decision-making and improve collaboration and innovation for fast results.
