Udacity originated from free computer science classes offered through Stanford University in 2011. Sebastian Thrun, then a Stanford professor, was inspired by the overwhelming response to his Stanford Introduction to Artificial Intelligence course, which enrolled 160,000 students.
The company was announced at the 2012 Digital Life Design conference, with initial funding from Charles River Ventures and $200,000 of Thrun's personal money. The first two Udacity courses started on February 20, 2012, with CS 101: Building a Search Engine being among the initial offerings.
In October 2012, Andreessen Horowitz led a $15 million investment round in Udacity, providing significant capital for expansion. The company grew rapidly, with 90,000 students enrolled in the initial two classes by March 2012.
A pivotal moment came in November 2013 when Thrun announced in a Fast Company article that Udacity had a "lousy product" and would pivot to focus more on vocational courses for professionals and "nanodegrees." This strategic shift addressed the need for job-ready technical skills rather than purely academic content.
In 2014, Udacity partnered with Georgia Institute of Technology and AT&T to launch the first "massive online open degree" in computer science, demonstrating its ability to work with academic institutions while maintaining focus on practical skills.
The company continued expanding through partnerships with major technology companies. In October 2017, Udacity launched the Learn ARKit program with Unity and partnered with Google for a scholarship initiative targeting web and Android application developers.
By 2018, Udacity was valued at over $1 billion despite not yet being profitable, having raised $163 million from noted investors including Andreessen Horowitz, Drive Capital, and GV.
The most significant development came in March 2024 when Accenture announced its acquisition of Udacity. This acquisition integrated Udacity into Accenture's LearnVantage suite, combining Udacity's educational expertise with Accenture's corporate training capabilities.
