Grammarly acquired email client Superhuman on Tuesday to expand its productivity suite AI.
Neither company disclosed the deal’s finances.
Rahul Vohra, Vivek Sodera, and Conrad Irwin formed Superhuman. Traxcn data shows that the company raised $114 million from a16z, IVP, and Tiger Global, valued at $825 million.
Superhuman can provide millions more professionals for the future and give our present users a new surface for agent collaboration that doesn’t exist anywhere else.
Email isn’t just another tool; it’s where professionals spend most of their day, making it ideal for organizing several AI agents simultaneously, Grammarly CEO Shishir Malhotra said.
This acquisition brought CEO Vohra and other superhuman workers to Grammarly.
Email is the top use case for Grammarly and the key communication method for billions. We will invest even more in the core Superhuman experience and build a new way of working where AI agents cooperate across the communication tools we use daily by partnering with Grammarly, said Superhuman CEO Rahul Vohra.

Superhuman has recently added AI-powered scheduling, responses, and categorization functions. Grammarly announced it would use Superhuman’s tech to create email AI agents. Grammarly noted that email remains a key use case.
Grammarly purchased collaborative productivity company Coda last year and promoted co-founder Shishir Malhotra to CEO.
Grammarly secured $1 billion from General Catalyst in a non-dilutive investment in May. The company would repay General Catalyst with a capped proportion of revenue generated with the venture firm’s money instead of equity.
