Grammarly just acquired email client Superhuman to boost its AI productivity platform. The deal terms remain undisclosed.
Superhuman, founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, raised over $114 million from big venture names like a16z and Tiger Global. Its last valuation stood at $825 million, per Traxcn.
Grammarly’s CEO Shishir Malhotra said the move will expand their AI agent collaboration right inside email — a hub where professionals spend tons of time. 
“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 Malhotra, CEO of Grammarly
Superhuman CEO Rahul Vohra and his team are joining Grammarly as part of the deal.
“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
Superhuman recently rolled out AI scheduling, replies, and categorization features. Grammarly plans to build advanced AI agents for email using Superhuman’s tech, highlighting email’s core role for its users.
This comes after Grammarly acquired productivity software Coda last year and promoted Coda’s co-founder Malhotra to CEO.
Back in May, Grammarly raised $1 billion through a revenue share deal with General Catalyst, avoiding equity dilution.
This acquisition doubles down on Grammarly’s AI play across communication tools.
