Grammarly – About

Grammarly was founded in 2009 in Ukraine by Alex Shevchenko, Max Lytvyn, and Dmytro Lider, initially as a grammar and spelling tool for students. Over time it evolved into a full AI-powered communication and writing assistance platform, now developed by Superhuman Platform Inc. and headquartered in San Francisco, with offices in Kyiv, New York, and Vancouver.

The platform serves over 40 million daily users and 50,000 organizations, including users at 96% of Fortune 500 companies. Its product suite — Grammarly Free, Premium, Business, and for Education — operates across more than 500,000 apps and websites, available as browser extensions, a standalone app, and integrations with tools like Google Docs. In April 2023, Grammarly launched generative AI features built on GPT-3, enabling content generation and rewriting from prompts, with enterprise-level customization of terminology and writing tone.

Grammarly is valued at $13 billion following its 2021 Series C round led by Baillie Gifford and BlackRock, and Sacra estimated its ARR reached $700M in May 2025. It operates a freemium SaaS model with approximately 80% gross margins. In December 2024, Grammarly acquired AI productivity tool maker Coda, and in 2025 it acquired Superhuman, rebranding its parent company as Superhuman Platform Inc. as part of a broader push toward an AI-native productivity platform.

For any organization evaluating AI writing, productivity, or communication tools, Grammarly's scale, enterprise adoption, and ongoing AI development make it a highly relevant benchmark and potential partner or competitive reference point in the AI productivity software space.

Ideas that could help Grammarly

Academic Italian Writing Coach
A web tool that helps researchers and students write better academic Italian by suggesting vocabulary organized by communicative function (e.g., 'to introduce a hypothesis', 'to contrast findings'), drawing directly on the DIA dictionary's function-based headword structure.
Why it helps: Grammarly lacks deep academic-register support for Italian; a partnership or licensing arrangement to integrate DIA's function-organized lexicon would fill this gap and expand its non-English market.
