Superhuman.

Superhuman started in 2014, when Rahul Vohra and his co-founders decided that email - the thing everyone hates and no one can quit - deserved to be fast. Not incrementally faster. Twice as fast, and beautiful about it. The pitch was keyboard shortcuts, a split inbox, and an interface tuned so obsessively that the loading screen had a target time. People who tried it tended not to go back.

The economics were unusual. Superhuman charged roughly $30 a month for email in a world where email is free and has been free since roughly forever. This sounds insane until you notice that the people paying were founders, executives and salespeople whose time is worth considerably more than $30 an hour. They were not buying software. They were buying the difference between an inbox that fights you and one that doesn't.

Vohra had done a version of this before. His earlier company, Rapportive, was the first Gmail plug-in to scale to millions of users, and LinkedIn bought it in 2012. So when Superhuman raised money - Andreessen Horowitz, IVP, Tiger Global, more than $125 million across its rounds - the bet was on a founder who understood that email is a habit, and habits are the most defensible thing in software.

By 2023 the email app was reportedly past $100 million in annual recurring revenue, with one of the highest retention rates in SaaS. Which is the moment the story gets strange. In 2025, Grammarly - the AI writing assistant used by tens of millions - acquired Superhuman. Grammarly had also, months earlier, acquired Coda, the doc-and-workspace tool run by Shishir Mehrotra, who then became CEO of the combined company.

Then came October 2025. The combined company - Grammarly plus Coda plus Superhuman - announced it was renaming itself. Not to some invented portmanteau. To Superhuman. The smallest of the three brands, by revenue, became the name of all of them. Alongside the rebrand came Superhuman Go, an AI assistant designed to work across your apps and quietly line up a team of agents before you even ask.

Why give the whole company the name of the thing you just bought? Because the name did work the company's own name couldn't. “Grammarly” is grammar. “Superhuman” is an ambition. When your ambition outgrows your name, the cheapest fix in all of business is to change the name - and this time, the name was already sitting in the building.

The famous Superhuman growth tactic is a thing that does not scale: a personal onboarding call for every single new user. In an industry obsessed with self-serve funnels, this was heresy. It was also the point. The call taught people the shortcuts, and the shortcuts created the habit, and the habit created the retention that made the whole subscription math work.

Vohra also became known for a product-market-fit survey now copied across Silicon Valley - the one that asks how you'd feel if you could no longer use the product - and for a counterintuitive rule: ignore most feature requests. Not out of arrogance, but because a product built for everyone's edge case becomes fast for no one. Superhuman picked speed and defended it.

And then there is the branding twist, which is genuinely rare. Acquirers almost always keep their own name. Here, the acquirer looked at three brands it owned and decided the smallest one carried the biggest idea. “Superhuman” describes an aspiration - being more capable than you were yesterday - and that turned out to be a better flag to plant than a word about grammar.

Whether the bet pays off is the open question. Bundling Grammarly, Coda, Mail and an agent assistant into one suite is a real strategy and a real risk: suites win when the tools finally talk to each other, and lose when they feel like three apps sharing a logo. Superhuman Go is the wager that the connective tissue is what people will pay for next.
