The Rise of Grammarly

Founded in 2009 by Ukrainian entrepreneurs Alex Shevchenko and Max Lytvyn, Grammarly began with a focus on helping students improve their writing skills by detecting plagiarism and correcting grammatical errors. Initially, it was marketed to educational institutions, but soon, the founders realized the potential of expanding it to a broader audience. They introduced Grammarly as a free Chrome extension, which allowed anyone to use it across multiple platforms.

The free extension became an instant hit, leading to rapid user adoption. By offering essential services for free, Grammarly built a massive user base, which laid the foundation for its future growth. Today, Grammarly has over 30 million daily active users, making it one of the most popular writing tools available​.

Business Model and Revenue Growth

Grammarly operates on a freemium business model. While the basic services are free, users can upgrade to premium plans that offer advanced features such as tone detection, vocabulary enhancement, and plagiarism checks. This model has proven to be highly effective, allowing Grammarly to generate substantial revenue while maintaining a large user base.

In 2021, Grammarly raised its valuation to $13 billion after a funding round that secured over $200 million. This impressive valuation is supported by the company’s strong financial performance. In 2023, Grammarly’s revenue was estimated to be between $100 million and $200 million annually. This growth is a testament to the company’s ability to monetize its services while continuing to expand its user base​.
