Grammarly to acquire email startup Superhuman in AI platform push

Grammarly has signed a deal to acquire email efficiency tool Superhuman as part of the company’s push to build an artificial intelligence-powered productivity suite and diversify its business, its executives told Reuters in an interview.

The San Francisco-based companies declined to disclose the financial terms of the deal. Superhuman, once an exclusive email tool boasting a long waitlist for new users, was last valued at $825 million in 2021, and currently has an annual revenue of about $35 million. Grammarly’s acquisition of Superhuman follows its recent $1 billion funding from General Catalyst, which gives it dry powder to create a collection of AI-powered workplace tools.
