When one of its founders, Vivek Sudera, urged him to travel to Hawaii for a business conference in 2017, Rahul Vohra hesitated. Superhuman, the AI-powered email company, was still in its early days, and the trip seemed like a distraction he couldn’t afford. But on his first afternoon by the pool, he met Shishir Mehrotra, an engineer who had worked at Microsoft and Google and who shared Vohra’s obsession with email productivity.
Vohra gave Mehrotra a demo, took his credit card, and recorded it on the spot. Mehrotra went on to invest in Superhuman and later co-founded the collaborative document platform Coda (originally called Krypton). When Grammarly acquired Coda in late 2024, Mehrotra became CEO of the combined company. In July 2025, Grammarly acquired Superhuman and rebranded the combined suite as Superhuman.
Vohra founded Superhuman in 2014 to address a familiar professional frustration: the elusive goal of “inbox zero.” Managing the constant flow of newsletters, promotions, and business messages can feel like a second job. Research by McKinsey and Microsoft shows that the average office worker receives what they receive Approximately 120 emails daily and spends about three hours — roughly 28 percent of the work week — managing them.
“That’s 3 billion hours every day spent reading and writing email, or over a trillion hours a year that go into that — and I couldn’t find a bigger problem to solve,” Vohra told Observer at Web Summit Vancouver earlier this month.
Vohra grew up in the UK and studied computer science at Cambridge. Before Superhuman, he founded Rapportive, a Gmail plugin that displays social profiles alongside emails, which was acquired by LinkedIn in 2012. This experience reinforced his view on the shortcomings of key communication tools for energy users. This gap was underscored when a Gmail product manager told him that the average user only manages two important emails per day. “I really realized how painful that experience was and how bad it was, and how these products Outlook and Gmail were designed for everyone, and therefore no one,” Vohra said.
Superhuman sits on top of Gmail or Microsoft 365, replacing the standard interface with a faster, keyboard-based experience. It uses artificial intelligence to sort messages before users see them, craft responses in their voice, and trigger follow-ups when recipients don’t respond.
Backed by Andreessen Horowitz, First Round Capital, and IVP, Superhuman has become one of the few venture-backed email companies to reach significant scale, reaching a valuation of $825 million and annual revenue of $35 million by 2021.
For most of its early history, Superhuman Mail operated without generative AI, prioritizing speed and efficiency. Unlike Gmail or Outlook, which fetches data on demand, Superhuman downloads everything locally to reduce loading times. Its simple, keyboard-based design and specialized features — like smart follow-up reminders and reading notifications by default — delivered a powerful user experience that larger platforms ignored. The emergence of generative AI in 2022 and 2023 has fundamentally reshaped the product, Vohra said.
Internal data shows that users who use Superhuman’s AI features handle 34 percent more email and save more than four hours per week. Clients including Spotify, Notion, OpenAI and Deel stress its appeal for high-performing teams. By contrast, Microsoft said Outlook Copilot users save about 30 minutes per week. Vohra added that one major consulting firm identified Superhuman and ChatGPT as the only AI products being widely purchased.
An autonomous productivity app in the era of Big Tech AI and “bio-coding”
Since its launch in 2014, Superhuman has built a loyal following among professionals willing to pay $30 to $40 a month for email despite free alternatives like Gmail and Outlook. This trade-off is becoming more controversial as AI tools make it easier to create custom software.
Vohra has been asking the same question for a decade: Why do we pay for email? His answer is straightforward. “I think there’s a big difference between free products, where you’re really the product… versus products where you’re actually paying to do good work.”
The debate has intensified with the emergence of the term “vibe coding,” or the use of artificial intelligence to create programs through plain English prompts — the top word of 2025 in Collins’ dictionary. In a Reddit thread titled “Rebuild Superhuman in 2 hours and save $40 per month“,” One developer described building a stripped-down alternative using Claude Code. “I think we are completely done with monthly fees for most programs,” the post read. He was ultimately outvoted more than he was voted on.
More experienced engineers are skeptical. One 15-year veteran of building email software using AI put it this way: “AI can power your email client in a weekend. What it can’t do is handle the thousands of instances that actually make email work. This includes keeping Gmail connections stable when credentials expire, preventing the execution of malicious code embedded in emails, and creating filters that reliably detect phishing attempts.
At the same time, competition is intensifying. Microsoft’s Copilot in Outlook and Google’s Gemini in Gmail have narrowed the gap in AI formulation and summarization, and have been integrated into existing workplace ecosystems. Corporate IT policies often restrict third-party tools, pushing users to return to virtual clients regardless of their preference.
For those committed to superhumanism, attractiveness is less about features and more about cognitive load. As one Reddit user put it, paying $30 a month beats “trying to make the square pegs of free apps fit into the round holes of my information ecosystem.”
Today, the rebranded Superhuman suite costs $33 per month and includes four products: Superhuman Mail, Grammarly’s writing AI, Coda’s collaborative workspace, and Superhuman Go, a cross-platform AI assistant. Whether that price is justified ultimately depends on how much users value their time and whether they trust a specialized tool rather than general-purpose AI for the hours they spend in their inbox.
