Grammarly nearly died as a paid product. Then it gave the product away for free, and became a $13 billion company with 40 million daily users. This is how the turn happened.

**The background.** Grammarly started in 2009 in Kyiv. Three Ukrainian founders: Max Lytvyn, Alex Shevchenko, and Dmytro Lider. They had just sold their previous startup, a plagiarism checker called MyDropBox, to Blackboard, and they put almost all of it, under $1 million, into the new company. As non-native English speakers, they knew the problem personally: writing without mistakes takes time, effort, and what Lytvyn calls psychological pressure. They wanted to make it easier.

When they described the idea, people split into two camps. The first said nobody needs this, everyone already has a spell-checker. The second, the people who understood the ambition, said it could not be done. The second group was closer to the truth. The founders wanted real-time feedback on writing, and that was not technically practical in 2009. Lytvyn's view was that the underlying technology had to progress on its own to make the vision possible, so they built what they could and waited for it to catch up.

**Six years of survival.** The first version was slow. You uploaded a document, pressed a button, and waited five to ten minutes for the result. The founders took no salaries until 2011 and nearly ran out of money several times.

Before spending everything, they tested demand with two "painted door" tests. First, they put up a consumer website advertising the product, but the checkout showed an error and asked people to come back later. The first purchase attempts came within hours. Second, they went to an education conference in San Francisco and pitched universities directly. Several showed purchase intent. That was enough proof to finish building.

So Grammarly launched as a paid subscription, sold mostly to students, and it had revenue from day one. The founders used it to fund development. "Our users paid for building the rest of Grammarly," Lytvyn says. By 2011 the company had 300,000 paying subscribers. Brad Hoover, an investor at General Catalyst who had come across the company, joined as CEO that year. Grammarly was cash-flow positive. It was also small: a niche tool for people patient enough to wait ten minutes for a grammar check.

**The layup.** Two things changed by the middle of the decade. The technology caught up: checking could finally happen in real time, as you typed. And the users had already shown the way. People were using Grammarly for everything, personal emails, professional writing, social posts, not just student essays. The market was not students who could pay. The market was everyone who writes.

**The turn.** In 2015, Grammarly made two moves at once. It went freemium: the core product became free, with paid plans on top. And it released a free browser extension, first for Chrome, then for Safari, Firefox, and Edge.

The extension was the distribution genius. Instead of asking people to visit a website and paste in text, Grammarly went to where people were already writing: email, LinkedIn, Google Docs, social media. Every time you wrote anything online, Grammarly sat there underlining your mistakes. The product demonstrated itself constantly, for free, inside the tools people used every day.

**The results.** Growth took off immediately. One million daily users in 2015, the year of the switch. 6.9 million daily users by 2017, most of them free. Thirty million by 2020.

The free tier was not charity. Free users get spelling and basic grammar. Paid plans, around $12 a month, add style, tone, fluency, vocabulary, and plagiarism checks. A heavy user hits the ceiling of the free tier alone, and the upgrade sells itself at that point. Grammarly took its first venture round, $110 million, only in 2017, eight years after founding, and it was already profitable. "Growing faster than anything we normally see in San Francisco," one of its new investors said at the time. By 2019 the company was valued at over $1 billion. In November 2021 it raised more than $200 million at a $13 billion valuation.

The same bottom-up motion worked inside companies. Individuals brought Grammarly to work, and teams followed. The company launched Grammarly Business, and by 2021 it served 30,000 professional teams, with enterprise customers including Zoom, Cisco, and Expedia. Distribution kept widening: an add-in for Microsoft Office, desktop apps for Windows and Mac, a mobile keyboard for iOS and Android, and a deal with Samsung that put Grammarly's suggestions inside the phone keyboard itself, no app install needed.

**What came beyond.** As of May 2025: over 40 million daily users, more than $700 million in annual revenue, still profitable. General Catalyst put in $1 billion of non-dilutive financing, essentially a bet on the customer-acquisition machine the freemium model built. The company acquired the document platform Coda in 2024 and the email app Superhuman in 2025, brought in a new CEO, and in October 2025 renamed the company Superhuman. The writing product is still called Grammarly. Management says it plans to go public eventually.

**Why free worked.** Grammarly checks three boxes that make freemium powerful. First, it is a daily-use product. You write every day, so the product becomes a habit, and habits spread by visibility. Second, the free version is genuinely useful, not a crippled trial, so people recommend it without being asked. Third, the extension turned every text box on the internet into a demo. The product was the marketing.

There is also a quieter point. Grammarly spent six years as a paid product before going freemium, and those years were not wasted. Selling to students taught the founders who needed the product most, and it kept the company alive on revenue instead of venture money. Freemium worked because there was a working business underneath it.

**The lesson for builders.** Prove people will pay first, then remove the paywall. Grammarly sold to everyone for six years and nearly died. Then it gave the product away and grew from one million to thirty million daily users in six years. A free tier works when you already know the product is worth paying for.
