Grammarly

Grammarly, the AI-powered writing assistant trusted by millions, has announced the acquisition of Superhuman, a leading email efficiency platform, in a move that signals its ambitions to become a comprehensive AI productivity powerhouse. The deal, confirmed on July 1, 2025, by executives from both San Francisco-based companies, marks a pivotal moment as Grammarly seeks to expand far beyond its roots in grammar correction and writing enhancement.

Superhuman: From Exclusive Email Platform to Grammarly’s AI Vision

Superhuman, founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, has become renowned for its innovative, AI-driven approach to email management. The company previously raised over $114 million from high-profile investors including Andreessen Horowitz (a16z), IVP, and Tiger Global, reaching a valuation of $825 million in 2021. Today, Superhuman generates an estimated $35 million in annual revenue and boasts a loyal user base that relies on its advanced features for faster, smarter email communication.

Strategic Rationale: Email as the Next AI Frontier

This is the future we’ve been building toward since day one: AI that works where people work, not where companies want them to work. 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 Mehrotra, CEO of Grammarly

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. These kinds of agents will free us all up to be more creative, strategic, and closer to achieving our human potential.

Leadership and Team Integration

As part of the acquisition, Rahul Vohra and more than 100 Superhuman employees will join Grammarly. Both companies have stressed that the Superhuman product, team, and brand will continue to operate, ensuring continuity for existing users while accelerating innovation under Grammarly’s umbrella.

Fueling Expansion with $1 Billion in Fresh Capital

This acquisition comes on the heels of Grammarly’s recent $1 billion funding round from General Catalyst, which provides the company with substantial resources to pursue its vision of building a suite of AI-driven workplace tools. Grammarly’s annual revenue now exceeds $700 million, and the company is reportedly considering a broader rebranding to reflect its expanding mission in the productivity space.

The Road Ahead: Competing in the AI Productivity Arena

With this deal, Grammarly is positioning itself to compete with tech giants like Google and Microsoft, both of which are rapidly integrating AI into their productivity suites. By leveraging Superhuman’s advanced email technology and its own expertise in AI-powered communication, Grammarly aims to offer a seamless, intelligent productivity experience to professionals worldwide.
