Edward Tian built GPTZero during his senior year winter break at Princeton, creating a tool to detect AI-generated writing. The site crashed within a week as 30,000 people rushed to use it. Less than four years later, GPTZero has over 20 million registered users and $30 million in annual recurring revenue. Superhuman, formerly known as Grammarly, acquired GPTZero in June for undisclosed terms. The deal represented at least a 10x return on the $13.5 million the company had raised. Tian, 26, and cofounder Alex Cui now lead Superhuman's authenticity team. Before GPTZero took off, Tian had accepted a fellowship with the New York Times' visual investigations team and studied under New Yorker writer John McPhee at Princeton. GPTZero's roughly 30 employees are being integrated into Superhuman's broader authenticity effort.

ZoomInfo has launched a connector for Superhuman Go, the AI assistant from Superhuman. The integration enables mutual customers to access ZoomInfo's verified GTM intelligence data directly within Superhuman Go. The connector reads from GTM.AI, ZoomInfo's headless GTM context layer, which spans 100 million companies, 500 million contacts, and billions of buying signals. Users can search for target accounts by industry size or tech stack, pull verified contacts by title and seniority, surface intent signals, and generate account or contact briefs before sales meetings. Superhuman Go joins existing GTM.AI integrations including Salesforce Agentforce, HubSpot Breeze, Microsoft Copilot Studio, Gong, Claude, ChatGPT, and Google Workspace. Authentication and governance remain tied to existing ZoomInfo and Superhuman permissions. The connector is now available to Superhuman Go customers with a ZoomInfo subscription.

Sectigo further automates security certificates with orchestration gateway. Superhuman acquires Otter AI transcription rival Fathom. 23rd September 2026 Vendor Superhuman looks set to buy an AI notetaking tool and integrate meeting data with its expanding AI-enabled productivity platform. According to Ivan Mehta, writing for IT publication TechCrunch, the move is about expanding AI-enabled automation opportunities. "With a notetaker, Superhuman can work on surfacing meeting context in real time," Mehta wrote. "Superhuman already has an email client, a docs app, a calendar, a database solution, and a newly launched AI agent builder platform." Also, it owns popular text-editing tool Grammarly. By adding a notetaker like Fathom, Superhuman can draft emails, update data entries, schedule follow-up meetings, and have AI agents work with meeting data. Generative AI tools can speed up certain types of task, such as transcription of what's said in a meeting. "Superhuman is joining the cadre of productivity platforms launching notetakers. But rather than building one internally, it is acquiring Y Combinator-backed Fathom," Mehta wrote. US-based Y Combinator funds tech start-ups. In addition, Fathom numbers Zoom Apps Fund, Telescope Partners, BoxOne Ventures, Character Capital, and Maven Ventures among its investors. Notetaker tools add meeting data to office AI. Subsequently, Mehta said Fathom has around 400,000 active users a month, potentially adding to Superhuman's 40 million customers. Shishir Mehrotra, Superhuman's CEO, told Mehta that creating its own notetaker would have been difficult. "It becomes clear how deep the products in this category are and how much you need to build. A lot of these products make the job feel really easy. It's actually quite tricky," Mehrotra was quoted as saying. Meanwhile, July saw Superhuman launch Docs, a type of AI assistant. The "collaboration surface" is an "evolution" of older team tool Coda, it said. "New capabilities move AI beyond the chat window and into the documents teams rely on, enabling them to build with AI together and create custom tools connected to their data," an announcement said. Superhuman said that Docs can read, plan, write, track, and build inside any document. ChatGPT, Claude, Cursor, and other AI clients can be connected. "Users describe what they need in plain language. Docs produces content, builds formatted tables, resolves comments, and pulls information across documents," it said. "AI views run on live data, with drag-and-drop interactivity and AI-powered actions. They automatically update as the underlying data changes." At the same time, Superhuman unveiled its Databases enterprise data management offering in private beta. The vendor said it supports up to a million rows per database. "Teams can centralise shared datasets, build trackers and operational systems," it said. "And connect that data directly to Docs so the same information is available across surfaces."
