Superhuman Acquisition
Superhuman was acquired by Grammarly for an undisclosed price on 1 July 2025.
Before the acquisition Superhuman had raised $108M across 2 funding rounds.
Superhuman Labs Inc. develops an AI-native email client compatible with Gmail and Outlook, offering shortcuts for efficient navigation, CRM integrations for salespeople, and recent AI features for message categorization, archiving low-priority emails, scheduling, replies, and text generation. The company, founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, raised over $114 million from investors including a16z, IVP, and Tiger Global, achieving an $825-850 million valuation in 2021 and generating $35 million in annual revenue. Grammarly Inc., a San Francisco-based AI writing assistant founded in 2009 with 40 million daily users across 500,000 organizations, acquired Superhuman on July 1, 2025, for an undisclosed amount to accelerate its evolution into an AI productivity platform centered on email as a hub for multi-agent collaboration. The strategic rationale positions email—where professionals spend over three hours daily and Grammarly's top use case—as the ideal surface for AI agents to automate tasks like rewriting emails, interacting with third-party systems, and orchestrating workflows, building on Grammarly's prior December 2024 acquisition of Coda for an AI workspace. Superhuman CEO Rahul Vohra and team joined Grammarly, whose CEO Shishir Mehrotra (from Coda) emphasized delivering AI where people work. Grammarly secured $1 billion in non-dilutive financing from General Catalyst in May 2025 to fund such deals. By October 29, 2025, Grammarly rebranded to Superhuman (formerly Grammarly), unifying assets under the Superhuman identity to amplify human potential amid AI commoditizing writing tools, enabling further acquisitions like AI startup Rows in 2026. Deal terms remain undisclosed across official announcements, with one speculative source claiming a $13 billion valuation unconfirmed by primary reports; the acquisition supports Grammarly's shift to a multi-product company with task-specific agents across communication tools.
