Grammarly has announced the acquisition of email startup Superhuman as it looks to expand its AI-powered productivity tools. While the financial terms were not disclosed, the deal marks a significant step in Grammarly’s strategy to integrate more AI into everyday workflows. Superhuman, which was founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, had raised over $114 million and was last valued at $825 million. With this acquisition, Vohra and the rest of the Superhuman team will join Grammarly to focus on developing new AI-driven experiences within email.
The decision underscores the continued importance of email in modern work. Grammarly’s CEO, Shishir Mehrotra, said that email is a natural fit for AI agents because it’s where professionals spend a large part of their day. He believes combining Grammarly’s existing tools with Superhuman’s fast, AI-enhanced email platform will unlock new ways for users to collaborate with intelligent agents across different communication tasks. This includes drafting, organising, and managing emails more efficiently.
Superhuman has been steadily introducing AI features, including smart scheduling, suggested replies, and email sorting. Now, with Grammarly’s backing, the team plans to improve these tools while also contributing to broader AI goals across the Grammarly ecosystem. Vohra said the partnership will allow both companies to invest more into the core email experience while also shaping a new way of working, one where multiple AI agents assist users across different platforms.
This is not Grammarly’s first major acquisition. Last year, it acquired Coda, a collaborative document platform, and appointed Coda’s co-founder, Shishir Mehrotra, as its new CEO. The move strengthened Grammarly’s focus on becoming more than just a writing assistant by evolving into a full productivity platform powered by artificial intelligence.
In May, Grammarly raised $1 billion from General Catalyst through a non-dilutive investment. This means the company avoided giving up ownership and will instead repay the investment through a portion of the revenue generated from its AI products. The Superhuman deal aligns with that growth strategy, bringing Grammarly closer to becoming a central hub for AI-driven communication and work tools.
