Superhuman is a workplace AI company built from three well-known productivity brands. It began in 2014 as a fast, keyboard-driven email client founded by Rahul Vohra. In 2025 the app was acquired by Grammarly, and that October the combined company - which also owns the writing assistant Grammarly and the workspace tool Coda - renamed itself Superhuman and launched an AI assistant called Superhuman Go. The company, led by CEO Shishir Mehrotra, now positions Superhuman as a suite of AI agents that work across email, documents and writing to amplify how people get work done.

Shishir Mehrotra is the CEO of Grammarly and co-founder of Coda, the all-in-one work OS that reinvented the document. A veteran of YouTube (as VP of Product, Engineering & UX), Microsoft, and MIT, he spent a decade rebuilding how teams work before Grammarly acquired Coda in December 2024, handing him the keys to a platform with 40 million daily active users. His intellectual fingerprints are all over Silicon Valley's obsession with meeting design, team rituals, and AI-native productivity.
