Grammarly bootstrapping story, organizational structure

And it was pretty much bootstrapped until 2017 when it got a venture funding for $110 million to further scale its operations. 

According to an interview for Voice of America, reported by Forum Daily Grammarly founders reported:

We saw a lot of plagiarism and wanted to help teachers and other students who honestly wrote their work to solve this problem.

Therefore, they wanted to solve a problem of plagiarism, and indeed we might argue that one of the key value propositions of Grammarly is its plagiarism checker able to check (according to the company) to billions of pages in a few seconds.

According to LinkedIn, the company has 302 employees as of October 2019, mostly distributed across the US and the Ukraine offices. According to LinkedIn, about 40% of the employees work in Engineering and IT which shows a strong focus on the product.

And around 32% of employees work in Sales and Marketing roles.

A glance at Grammarly technolgy-driven approach

As a company that automates most of the processes related to grammar and sentence structure. Grammarly has to leverage on several technologies to make this process work.

For instance, what might seem a very simple task, like splitting sentences has to have natural language capabilities. As the Grammarly engineering team explains:

At Grammarly, we use a lot of off-the-shelf core NLP technologies to help us make a little bit of sense in the mess that is natural language texts (English in particular). The issue with all these technologies is that even small errors in their output are often multiplied by the downstream algorithms. So, when a sophisticated mistake-detection algorithm is supposed to work on individual sentences, but it receives a fragment of a sentence or a couple merged together, it may find all sorts of funny things inside.

The major strength of the company is how they’ve been able to release these at a massive scale. In 2019 Grammarly reported over 20 million users, which might make also a simple NLP task quite complex.

Another key element to understand how technology-supported Grammarly growth is its ability to make its browser extension work at scale.


The browser extension reported over 10 million users as of October 2019. And it has been a key element to enable Grammarly viral growth. Indeed, the freemium is most of all a marketing tool that should enable companies to cheaply acquire leads that can be converted in paying customers.

In Grammarly’s case, a browser expension might seem a simple thing, yet as the Grammarly engineering team specified:

These extensions may look easy on the outside because they are low profile and easy to use. But it is actually a complex product supported by a full team of engineers. We have been developing and perfecting it for 6 years.

That is why the engineering team has implemented a branching model to reduce manual tasks, which as you can imagine, on a user base of 20 million might be impossible to keep up for a company with a few hundreds of employees of which only about 24 people in support, according to LinkedIn:

In these cases, technology and engineering are the most important marketers, as they enable a free product to scale, thus making the brand resonate across millions of users across the world.  

What’s a Grammarly competitive advantage? A platform-agnostic AI tool

A competitive advantage is not easy to identify and it is often related to multiple factors. In this paragraph, we’re focusing on one particular competitive advantage, but it is important to highlight this isn’t the only one that makes Grammarly tick so far.

Hoover, Grammarly’s CEO explained to TechCrunch what one of the key advantages of Grammarly is its “platform-agnostic approach.” In short, Grammarly focuses on being anywhere the user needs to be.

This is a great advantage in an era where competition for AI tools is increasing substantially and also large tech companies like Google are providing automation tools for writing. However, those are still closed platforms with their own business logic. Grammarly goes beyond that.
