What happened
Superhuman has acquired Fathom, a notetaker backed by Y Combinator, according to TechCrunch.
Fathom said it has more than 400,000 monthly active users.
The deal comes as productivity platforms push further into agentic work.
Why it matters
The acquisition folds a notetaking tool with a sizable reported user base into Superhuman's productivity lineup, suggesting consolidation is underway among tools that capture and organize work conversations.
The framing around agentic work indicates that productivity vendors increasingly see automated, assistant-style capabilities as the competitive ground, and buying an established notetaker could be a faster route than building one.
