Coursera - a hundred thousand students in a lifetime, delivered in a few weeks
Two Stanford professors put three courses online in 2011 and each drew more students in weeks than either could teach in a career; in 2026 the company they founded absorbed Udemy and became the largest learning platform there is.
Coursera is an American online learning platform founded in 2012 by Stanford professors Andrew Ng and Daphne Koller, offering university and industry courses, certificates and degrees; it completed its combination with Udemy in 2026.
On 16 August 2011 a few Stanford professors announced that three of their computer-science courses would be offered free online. Within weeks each had more than a hundred thousand people enrolled - more, as the company's own account puts it, than any of the professors could hope to teach in an entire lifetime. There had been no marketing. Daphne Koller called it a wake-up call about demand, and in 2012 she and Andrew Ng left to build the platform, signing Princeton, Penn and Michigan within months, with no plan for making money and investors who joined anyway.
The model that emerged is the university's: institutional partners supply courses and their names, learners may study free and pay for the verified credential, and the certificate carries the partner's authority rather than the platform's. The company listed in 2021, passed a hundred million registered learners in 2022, and by late 2025 had over 190 million. Its revenue, though, comes less from those learners than from their employers, and the platform fee it began charging its university partners in 2026 - fifteen per cent - marked the moment the platform's interests and its content suppliers' visibly diverged.
Then it bought the other model. On 17 December 2025 Coursera and Udemy announced an all-stock combination; the prospectus later showed Coursera had approached three times over two years and that a rival, the owner of Pluralsight, had bid cash. Stockholders approved on 9 April 2026 and the transaction closed in May: 290 million learners, eighteen thousand enterprise customers, ninety-five thousand instructors, under the Coursera name. The two companies had paid their instructors and university partners an estimated 440 million dollars in 2025.
For anyone whose living is teaching, that last number is the one to watch, because the combination puts the credentialed model and the open-marketplace model under one owner with one set of margins to protect. The vendor training centres elsewhere in this list sell scarce, certified instruction of specific products; a platform of this size sells abundance. Both exist because a course's value depends on who is on the other side of it, and the industry has not settled which side that is.
- Coursera's own tenth-anniversary account: on 16 August 2011 a group of Stanford professors announced three massive open online courses, and within weeks more than 100,000 learners had enrolled in each - more students than any of the professors could hope to teach in a lifetime; Daphne Koller and Andrew Ng launched Coursera in 2012
- Daphne Koller, founder profile: the classes used short video lectures, forums, quizzes and peer-graded homework; with no marketing each had more than 100,000 learners, which she called a wake-up call about demand; within months Princeton, Penn and Michigan signed on; the company had no monetisation plan and investors joined anyway
