Grammarly

Grammarly develops AI-powered writing assistance software that helps users improve their written communication across digital platforms. The company was founded in 2009 by Alex Shevchenko, Max Lytvyn, and Dmytro Lider, and is headquartered in San Francisco, California.

The company's primary product is a digital writing assistant that provides real-time grammar, spelling, punctuation, and style suggestions. Grammarly operates through browser extensions, desktop applications, mobile keyboards, and integrations with Microsoft Office and Google Workspace. The platform serves over 30 million daily active users, including individual consumers, educational institutions, and enterprise customers such as Cisco, Databricks, and Zoom.

Grammarly has raised approximately $400 million in funding, including a $200 million Series C round in November 2021 led by Baillie Gifford and BlackRock that valued the company at $13 billion. The company employs over 700 people across offices in San Francisco, New York, Vancouver, and Kyiv. In 2019, Grammarly acquired Koko, a company focused on emotional intelligence technology.
