Superhuman

Superhuman is a productivity-oriented email application that enhances user efficiency and collaboration through AI-powered functionalities, enabling users to manage their inbox optimally and streamline communication workflows. Superhuman was founded in 2015 by Bryan Cutter, Conrad Irwin, Paul Masters, Rahul Vohra, Van Horgen, and Vivek Sodera, and is headquartered in San Francisco, US. Superhuman offers a productivity-focused email application designed to enhance user efficiency and collaboration through AI-driven functionalities. The core product delivers an AI-powered inbox assistant that organizes incoming emails, automates responses, and facilitates workflow management, ensuring users never miss critical communications.

Key features include the Split Inbox, which prioritizes emails from specific teams or tools; Snippets for automating email content; and real-time collaboration tools that allow team members to comment on emails, regardless of whether they use Superhuman. Targeted primarily at professionals and teams using Gmail or Outlook, Superhuman serves a diverse clientele, including businesses in sectors such as Sales, Marketing, Engineering, and Customer Success across various geographical markets, including North America, Europe, and Asia. In July 2025, Grammarly Inc. , a portfolio company of Institutional Venture Partners, General Catalyst Partners, Spark Capital, BlackRock, Breyer Capital, SignalFire, and Baillie Gifford, acquired Superhuman from Boldstart Ventures, Fueled, Andreessen Horowitz, Yes VC, Institutional Venture Partners, and Tiger Global Management for an undisclosed amount.

  Superhuman generates revenue primarily through subscription models tailored to individual and team usage of its email application. The platform offers various pricing plans structured to cater to both small teams and larger enterprises, with features scaling according to user needs. Transactions typically involve direct subscriptions for individuals or organizational licenses, allowing businesses to enhance their email management capabilities. The focus is on delivering premium service through its flagship product, which is designed to save users significant time and increase productivity.

The subscription model fosters recurring revenue, as clients benefit from continuous updates and enhancements to the Superhuman platform. The acquisition will enable Grammarly's transformation into an AI-driven productivity platform for applications and agents, highlighting email as a key communication channel.
