Grammarly has announced the acquisition of Superhuman, a premium email startup, in a bold move to expand its AI-powered productivity ecosystem beyond writing assistance. The financial terms of the deal remain undisclosed, but Superhuman was last valued at $825 million in 2021 and currently generates about $35 million in annual revenue.
The acquisition marks another strategic step in Grammarly's evolution following its recent $1 billion funding round led by General Catalyst. With over 40 million daily users and $700 million in annual revenue, Grammarly is actively repositioning itself as a broader AI productivity platform, even planning a rebrand to reflect this shift.
Superhuman, known for its sleek, fast email interface and once-notorious waitlist, will continue operating under its own brand. CEO Rahul Vohra and over 100 team members will join Grammarly as part of the deal. Vohra said the acquisition brings access to “significantly greater resources” and opens doors to expand into new productivity areas like calendars, tasks, and collaboration.
“Email remains the world’s most-used work app,” said Shishir Mehrotra, Grammarly CEO and former Coda co-founder. “Superhuman is the obvious leading innovator in the space.”
The companies aim to integrate Grammarly’s AI agents into Superhuman, building intelligent tools for professionals and enterprises. These agents will navigate across emails, documents, and tasks to automate workflows, eliminate information silos, and reduce time spent on communication-heavy tasks.
Grammarly now joins a fierce race among AI productivity platforms, facing off against Microsoft, Google, Salesforce, and emerging startups.
