Grammarly Acquires Superhuman in Power Move to Dominate AI Productivity Tools

Grammarly just made its boldest play yet—snagging Superhuman to turbocharge its AI ambitions. This isn’t just another acquisition; it’s a direct shot across the bow of Microsoft and Google.

Why Superhuman? Speed. The email client’s cult-like following swears by its efficiency—exactly what Grammarly needs to morph from grammar cop to full-fledged productivity overlord.

Wall Street’s already salivating. Because nothing says 'bullish' like two startups with zero profits merging to chase the same enterprise customers drowning in 37 other SaaS tools.

One thing’s clear: The AI arms race just got a new contender. And this time, it’s coming for your inbox.

TLDRs;

• Grammarly has acquired email startup Superhuman to strengthen its AI productivity tools.
• Superhuman’s team, including founder Rahul Vohra, will join Grammarly to build AI email agents.
• The move follows Grammarly’s earlier acquisition of Coda and a $1 billion investment aimed at strategic growth.
• The deal underscores the growing trend of AI consolidation across productivity platforms.

Grammarly has acquired premium email startup Superhuman in a MOVE that signals its intent to broaden its AI productivity suite and solidify its position in the evolving landscape of workplace tools.

The acquisition brings together two companies with strong reputations for elegant design, AI integration, and a focus on improving the way professionals communicate.

Superhuman, known for its fast, minimalist email client, was founded by Rahul Vohra and had raised over $114 million from top-tier investors including Andreessen Horowitz, IVP, and Tiger Global. Its last known valuation stood at $825 million. While the final purchase price remains undisclosed, Grammarly’s strategic interest clearly lies beyond valuation. Vohra and several key team members will now join Grammarly, bringing their expertise to help build advanced AI agents for email management.

Grammarly bets big on AI-enhanced email

The acquisition comes as Grammarly continues to reshape its identity from a grammar-checking assistant into a fully-fledged AI productivity platform. By acquiring Superhuman, Grammarly is doubling down on a domain that remains central to professional life, the email. While numerous alternatives have promised to disrupt or replace it, email remains the default communication tool in most businesses.

Superhuman had recently introduced AI-powered features to automate scheduling, streamline responses, and declutter inboxes. Grammarly sees an opportunity to build on this progress and integrate these features into its broader suite of offerings. According to Grammarly, email remains the number one use case for its existing customers, reinforcing the logic behind the acquisition.

A pattern of strategic acquisitions

This is not Grammarly’s first bold move in the productivity space. In late 2024, the company acquired document collaboration startup Coda, bringing in Coda CEO Shishir Mehrotra as Grammarly’s new chief executive.

That acquisition focused on expanding Grammarly’s footprint into collaborative writing and documentation, an area where Coda had carved out a strong niche. With Superhuman now joining the fold, Grammarly is assembling a multi-pronged AI productivity stack across writing, collaboration, and communication.

These acquisitions are being powered by significant financial backing. Grammarly secured a $1 billion investment from General Catalyst in May 2025, earmarked specifically for accelerating growth through strategic acquisitions and scaling go-to-market efforts. With annual revenue exceeding $700 million and a user base of more than 40 million, Grammarly appears to be executing on a long-term vision to become the dominant platform for AI-enabled workplace productivity.

AI consolidation continues across the sector

Grammarly’s move echoes a broader trend sweeping through the productivity software industry. As artificial intelligence becomes the foundation of modern work tools, major platforms are absorbing point solutions to create more comprehensive ecosystems.

Just as Microsoft acquired Intentional Software and Atlassian picked up Trello to bolster their productivity suites, Grammarly is now doing the same with Superhuman.

What makes Grammarly’s strategy notable is how it aligns its acquisitions with both customer demand and product synergy. The company isn’t just collecting startups for expansion’s sake. It is choosing assets that reinforce its Core mission: helping people communicate clearly, efficiently, and intelligently.
