Superhuman
A fast, keyboard-driven email app for high performers, now with AI features and team collaboration.
Superhuman acquired GPTZero, which had scaled past $30M ARR, gaining distribution through its Chrome extension with 40M+ users and 14+ years of growth and seasonality experience. The CEO called it a reverse acquisition, and the combined team is named SAGE. For app builders: reuse user content as paid ads, give acquired teams a shared identity fast, and build the AI filter users ask for, even years later.

From Edward Tian on GPTZero and Superhuman
What was said about Superhuman
GPTZero built its AI filter only once users wanted it. The seed coverage of GPTZero described an AI filter for browsing, but the team built it two or three years later, when demand appeared. The Chrome extension now tags AI content on LinkedIn, Twitter and Gmail.
Edward Tian sees a tipping point where people want to filter slop from what they consume. The extension distribution is supported by Superhuman's Chrome extension, which has 40M+ users and 14+ years of seasonality and growth experience. Quote: "we are at a tipping point where people want to talk more about this"
GPTZero will rerun its best creator content as paid ads. With Superhuman's paid and PLG experts, GPTZero plans to take its best-performing user-generated content and run it as paid ads.
Content already proven with creators gets scaled with budget, which creates a cycle between organic and paid. Quote: "you have UGC content you can rerun it as paid ads as well you kind of like create that virtuous cycle"
Superhuman gave the acquired GPTZero team a shared identity within a week. On day one the Superhuman CEO said he wanted one team wearing the same sweater. Within a week the combined team picked a name by vote, SAGE (student authenticity, GPTZero and education), made sweatshirts and held a retreat.
The Superhuman CEO called the deal a reverse acquisition. Edward keeps the culture alive by repeating the team rhythm and giving shoutouts when others follow it. Quote: "you just have to like put your foot in the ground and say like, Hey, we're consistently doing the rhythm."
