The people who built United States's companies · November 2026

AI productivity software: email client (Superhuman Mail), writing assistant (Grammarly), docs (Coda)

Superhuman

Superhuman built a $30-a-month email app for people who wanted speed, with heavy keyboard shortcuts, and claimed regular users could save up to three hours a week.

In October 2025 a company did something rare. Grammarly, one of the best-known writing tools in the world, dropped its own name. Its parent became Superhuman Platform Inc. Three months earlier it had announced it would buy Superhuman, a paid email app, for an undisclosed sum.

The name came from a small product. Rahul Vohra founded Superhuman in 2014 and aimed it at people who live in their inbox. It charged $30 a month, and $10 for students. It leaned on keyboard shortcuts, and its pitch was that a regular user could save up to three hours a week. It worked only with Gmail at first; Outlook arrived in May 2022. Over the years it raised more than $100 million, including from Andreessen Horowitz. Vohra's birthplace and schooling did not turn up in the sources read for this profile, so the story starts with the product.

It leaned on keyboard shortcuts, and its pitch was that a regular user could save up to three hours a week.

The buyer had a different origin. Grammarly was founded in 2009 in Ukraine by Max Lytvyn, Alex Shevchenko and Dmytro Lider. It grew into a household name, raised $200 million in 2021 at a $13 billion valuation, and kept that number as its last public mark. It also lived through a scare: in 2018 a browser-extension flaw exposed authentication tokens, and the company patched it within hours. The same year it offered $100,000 to anyone who could reach one specific document on its server.

War tested it more. After Russia invaded Ukraine in 2022, Grammarly stopped operating in Russia and Belarus, and it kept paying staff who joined the Ukrainian army.

Then the deals came fast. Coda in December 2024, with its founder Shishir Mehrotra taking over as chief executive. A $1 billion non-dilutive financing from General Catalyst in May 2025. Superhuman in July. The rebrand in October, with an AI suite built around the new name. Rows, an AI spreadsheet startup, followed in February 2026.

The price of speed showed in March 2026. A feature called Expert Review appeared to offer feedback from famous writers, among them Stephen King and Kara Swisher, without their permission. A class action followed and the feature was dropped.

The numbers are still hazy. No revenue figure was found, and the $13 billion mark dates from 2021. What is clear is the bet: that an email client and a writing assistant belong in one AI work suite, under one name.

For founders, the lesson is about what a brand is worth. A 16-year-old name chose to retire itself in favor of a product people loved to use fast. Sometimes the small thing you built carefully carries more weight than the large thing you built first.
