In this episode of This Week in Startups, Jason Calacanis welcomes Shishir Mehrotra, CEO of Superhuman, to discuss the company's acquisition strategy and AI integration. Shishir details three recent acquisitions: Rose (a Portuguese spreadsheet company), GPTZero (the leading AI detector), and Fathom (a note-taking tool). The conversation explores the tension between AI assistance and human capability, particularly in education and the workplace, where writing proficiency has become a critical concern. Jason shares frustration that new college graduates cannot write coherent sentences, prompting discussion about how tools like Grammarly can both augment and replace human skill. The episode also covers product strategy, the distinction between "assist," "chat," and "do" AI paradigms, and introduces a new tactical newsletter focused on actionable startup advice. Finally, Jason discusses Tesla's flying Roadster demonstration, corporate espionage at OpenAI, and legal action against OpenAI over child safety concerns, highlighting tensions between innovation and responsibility in AI development.

Today’s show:
Today’s college grads are showing up to work at Jason’s company unable to write three sentences. He’s asking what Shishir Mehrotra of Superhuman, the company behind Grammarly, can do to fix that.
Shishir delves into Superhuman’s reasons for acquiring GPTZero, the most popular AI detector, and the AI notetaker Fathom, and the spreadsheet startup Rows. Plus, how Shishir responds to accusations that Grammarly helps students cheat in the classroom, why writers should disclose when they’re collaborating with an LLM, and Jason's CEO wish list for fresh Grammarly features.
In the news, Tesla demoed its long-awaited Roadster, which used SpaceX thrusters to do some flips and propel itself over five other Teslas… And OpenAI warned staffers that spies may be trying to seduce them in order to steal company secrets… And the shutdown of Character AI prompts Jason to declare: “AI relationships are evil.”
