Grammarly to Acquire AI Email Client Superhuman

Grammarly announced on Tuesday that it is acquiring email client Superhuman as part of its effort to build AI for its suite of productivity tools. Neither company provided details about the financial terms of the deal.

Superhuman was founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin. The company has raised more than $114 million from investors including a16z, IVP, and Tiger Global, with its latest valuation standing at $825 million, according to data from venture data analytics firm Traxcn.

The Companies' Leadership Vision

"With Superhuman, we can deliver this future to millions more professionals while giving our existing users another interface for collaborating with agents that simply does not exist anywhere else. Email is not just another application; it is where professionals spend a significant portion of their day, and it is the perfect setting for coordinating multiple AI agents simultaneously," Shishir Mehrotra, CEO of Grammarly, said in a statement.

As part of the deal, CEO Vohra and other Superhuman employees are joining Grammarly.

"Email is the primary communication tool for billions of people around the world and the number one use case among Grammarly customers. By joining forces with Grammarly, we will invest even more in the core Superhuman experience, while also creating a new way of working in which AI agents collaborate across the communication tools we all use every day," Rahul Vohra, CEO of Superhuman, said in a statement.

Recent Developments in AI Features

Over the past few months, Superhuman has released AI-powered features related to scheduling, replies, and categorization. In its announcement, Grammarly said it intends to build AI agents for email using Superhuman's technology. The company said that email remains one of Grammarly's primary use cases.

Context of Previous Acquisitions and Investments

Last year, Grammarly acquired collaborative productivity software Coda and, as part of the deal, promoted Coda co-founder Shishir Mehrotra to CEO.

In May, Grammarly secured $1 billion from General Catalyst in a non-dilutive investment. Instead of giving up an ownership stake, the company will repay General Catalyst with a capped percentage of the revenue it generates using the venture firm's funds.
