Grammarly announced Tuesday the acquisition of email client Superhuman in a push to build out its AI for its productivity suite. Neither companies provided details about the financial terms of the deal.
Superhuman was founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin. The company raised more than $114 million in funding from backers including a16z, IVP, and Tiger Global, with its last valuation at $825 million, according to data from venture data analytics firm Traxcn.
“With Superhuman, we can deliver that future to millions more professionals while giving our existing users another surface for agent collaboration that simply doesn’t exist anywhere else. Email isn’t just another app; it’s where professionals spend significant portions of their day, and it’s the perfect staging ground for orchestrating multiple AI agents simultaneously,” Shishir Mehrotra, CEO of Grammarly, said in a statement.
With this deal, CEO Vohra and other Superhuman employees are moving over to Grammarly.
“Email is the main communication tool for billions of people worldwide and the number-one use case for Grammarly customers. By joining forces with Grammarly, we will invest even more in the core Superhuman experience, as well as create a new way of working where AI agents collaborate across the communication tools that we all use every day,” Rahul Vohra, CEO of Superhuman, said in a statement.
In the last few months, Superhuman has released AI-powered features related to scheduling, replies, and categorization. In its announcement, Grammarly said that it wants to build AI agents for emails using Superhuman’s tech. The company said that email remains one of the top use cases for Grammarly.
Last year, Grammarly acquired collaborative productivity software Coda, and as part of the deal, promoted Coda’s co-founder, Shishir Mehrotra, to CEO.
In May, Grammarly raised $1 billion from General Catalyst in a non-dilutive investment. Rather than giving up equity, the company will pay back General Catalyst the money with a capped percentage of revenue it creates using the venture firm’s money.
