Who Owns Grammarly?

Grammarly's founders built a plagiarism detection service called MyDropbox for universities before turning to consumer writing tools. Max Lytvyn and Alex Shevchenko, working in Kyiv with engineer Dmytro Lider, launched the first Grammarly product in 2009 as a paid grammar checker aimed at students and professionals.

The company stayed self-funded and profitable for almost a decade, an anomaly in consumer software. Its first institutional round came in 2017, a $110 million raise led by General Catalyst. By then the product had evolved from a grammar checker into a real-time writing assistant delivered through browser extensions, desktop apps, and mobile keyboards, reaching tens of millions of users.

Growth compounded through the late 2010s. The free tier spread virally inside documents and emails, and paid subscriptions added tone, clarity, style, and business features. The company opened offices in San Francisco, Vancouver, and elsewhere while keeping its engineering core in Kyiv, and raised to a $13 billion valuation in November 2021.

Generative AI reset the product roadmap. GrammarlyGO launched in April 2023 with text generation and rewriting, and the product later added agents for proofreading, paraphrasing, plagiarism, and AI detection. When ChatGPT commoditized basic writing help, the company's answer was distribution: it pointed to the more than 500,000 apps and websites where its extension already lived.

The 2025 acquisition spree changed its place in the org chart. The parent bought Coda in January 2025 and the Superhuman email app later that year, then renamed the whole company Superhuman in October. Grammarly became one product inside a suite, with its writing features embedded in the new Superhuman Go assistant, though it still sells standalone under its own brand.
