What is Grammarly?
Grammarly is an AI-powered writing and communications platform that helps 40 million daily users write with greater clarity, correctness, and confidence across more than 500,000 applications — from Gmail and Slack to Microsoft Word and enterprise knowledge bases.
Founded in Kyiv, Ukraine in 2009 by Max Lytvyn, Alex Shevchenko, and Dmytro Lider, Grammarly grew from a browser extension fixing grammar errors for students and non-native English speakers into one of the most widely adopted AI productivity tools in the world. The platform covers the full writing workflow: real-time grammar and spelling correction, tone adjustment, clarity rewrites, plagiarism detection, and — since its March 2023 announcement and April 2023 rollout — generative AI co-writing via GrammarlyGO. It integrates across the web via browser extensions, a desktop app for Mac and Windows, iOS and Android mobile keyboards, and a Microsoft Office add-in.
Grammarly reached approximately $700M+ in annual recurring revenue (ARR) by 2025, up from $500M in 2022, with gross margins around 80%. The company serves more than 50,000 organizations on its business and enterprise tiers alongside tens of millions of individual subscribers. In December 2024, Grammarly acquired collaborative workspace startup Coda, bringing on Coda co-founder Shishir Mehrotra as CEO. In June 2025, it acquired email productivity tool Superhuman (last valued at $825M), and in October 2025 rebranded the parent company as Superhuman while keeping the Grammarly product identity intact. In February 2026, the parent company acquired Portuguese spreadsheet-AI startup Rows to strengthen Coda's data workspace capabilities.
Grammarly competes directly with Microsoft Editor, ProWritingAid, Writer.com, and newer generative AI entrants such as Wordtune and Jasper AI. Its defensible position rests on deep OS-level integrations, a large proprietary writing-quality dataset built over 15+ years, and a freemium model that funnels tens of millions of free users into paid seats over time.
What does Grammarly offer?
Grammarly's product portfolio spans AI writing assistance, generative co-writing, enterprise communication governance, plagiarism detection, and — post-acquisitions — collaborative documents, intelligent email, and AI-powered spreadsheets.

How does Grammarly make money?
Grammarly generates revenue through a freemium SaaS model with Free, Pro, and Enterprise tiers, and an expanding enterprise motion driven by seat-based expansion across its growing product suite.
The Free tier offers basic grammar and spelling corrections plus 100 AI prompts per month, serving as the top-of-funnel acquisition engine for tens of millions of users globally. Grammarly Pro costs $12 per member per month (billed annually) or $30 month-to-month, unlocking 2,000 AI prompts, full-sentence rewrites, plagiarism detection, tone suggestions, and team features such as style guides and custom brand tones — supporting up to 149 seats. Enterprise is custom-priced for 150+ users and adds unlimited AI usage, SAML SSO, advanced admin controls, dedicated support, and compliance features (SOC 2 Type II, ISO 27001). A quarterly billing option is also available for standalone Pro at $60 per quarter.
With ~80% gross margins and a user base skewed toward non-native English speakers in India, the Philippines, and other high-growth markets, Grammarly's unit economics are structurally strong. Revenue grew over 40% year-over-year in 2024 before moderating, with ARR exceeding $700M by mid-2025. The $1B non-dilutive financing raised in May 2025 from General Catalyst's Customer Value Fund is designed to accelerate enterprise sales, agentic AI product development, and the integration of Coda, Superhuman Mail, and Rows into a unified Superhuman productivity suite.
Revenue diversification is expanding rapidly: Coda monetizes via per-Doc-maker seats ($10–$30/user/month), Superhuman Mail at $30/user/month, and Rows brings no-code spreadsheet-AI capabilities that will be absorbed into Coda. This gives the Superhuman parent three distinct SaaS revenue streams — writing governance, collaborative documents, and email productivity — cross-sold to overlapping B2B buyers. Enterprise deals increasingly bundle multiple products, raising average contract values.
Who leads Grammarly?
Grammarly (operating under the Superhuman parent brand since October 2025) is led by CEO Shishir Mehrotra, three Ukrainian co-founders, and a C-suite of IPO-experienced operators hired in 2024.
- Shishir MehrotraCEO, Superhuman (parent of Grammarly)January 2025–presentCo-founder and former CEO of Coda; previously CPO/CTO of YouTube (2008–2015); joined as CEO following Grammarly's acquisition of Coda in December 2024.

john.doe@grammarly.comHow much funding has Grammarly raised?
Grammarly has raised over $1.55 billion in total capital — $545M in equity across three disclosed rounds and a $1B non-dilutive financing facility closed in May 2025. The equity valuation has been held at $13 billion since the November 2021 Series C.
Grammarly operated entirely bootstrapped from 2009 to 2017, funded by proceeds from the co-founders' earlier plagiarism-detection service, MyDropBox. The first outside capital arrived in May 2017: a $110M Series A led by General Catalyst, at a time when Grammarly already had 7 million daily users and was profitable. A $90M Series B followed in October 2019, also led by General Catalyst, formally pushing the company's valuation past the $1 billion unicorn threshold. Notable co-investors across both rounds include IVP, Spark Capital, Breyer Capital, and SignalFire.
In November 2021, Grammarly raised $200M in a Series C led by Baillie Gifford and BlackRock, valuing the company at $13 billion — roughly a 33× multiple on estimated ARR of approximately $350–400M at the time. No equity down-round has occurred since; in May 2025, General Catalyst's Customer Value Fund provided $1B in non-dilutive revenue-based financing, deliberately structured to avoid issuing new equity at a potentially lower valuation than the 2021 peak. Total disclosed capital stands at over $1.55B.
Grammarly remains private as of June 2026. The CFO hire (Navam Welihinda, HashiCorp IPO veteran) and CTO hire (Mark Schaaf, Instacart IPO veteran) in September 2024 are widely read as IPO preparation signals. CEO Shishir Mehrotra has stated publicly that an IPO will happen "when we feel ready," though no filing timeline has been confirmed. With ARR now exceeding $700M, ~80% gross margins, and institutional investors (Baillie Gifford, BlackRock) on the cap table, Grammarly is well-positioned for a public offering in the 2026–2027 window.
How did Grammarly get here?

Who are Grammarly's competitors?
Grammarly competes across consumer AI writing tools, enterprise communication governance, and collaborative productivity suites.

- Jasper AIGenerative AI content creation for marketing teams; competes on long-form content generation and brand voice but lacks Grammarly's real-time correction and cross-app ubiquity.
- Hemingway EditorLightweight readability tool focused on reducing passive voice and complexity; free/low-cost for individual writers but has no generative AI or enterprise features.
