Spotify has revealed during its fourth-quarter earnings call that its best developers “have not written a single line of code since December,” relying instead on an internal system called “Honk” that leverages Claude Code for AI-assisted software development.
This stunning admission from Spotify co-CEO Gustav Söderström signals a fundamental transformation in how major tech companies approach software engineering.
Claude Code AI: 50+ Features Shipped with AI-Powered Development
The numbers tell a remarkable story. Throughout 2025, Spotify shipped over 50 new features and improvements to its streaming platform, with the development process increasingly dominated by AI assistance rather than traditional hand-coding.
Recent launches include AI-powered Prompted Playlists that create custom collections based on natural language descriptions, Page Match functionality for enhanced audiobook discovery, and About This Song feature providing contextual information about tracks—all developed with significant AI involvement.
Spotify’s “Honk” system integrates Claude Code to handle much of the actual code generation, allowing human engineers to focus on higher-level architecture decisions, feature specifications, and quality assurance.
The company reports that this approach has dramatically accelerated development cycles while maintaining code quality through rigorous testing and review processes.

AI Acceleration Reaches Tipping Point
The implications extend far beyond Spotify. If one of the world’s leading technology companies can successfully develop production software with minimal traditional coding, it validates the viability of AI-powered development at enterprise scale.
This represents a fundamental shift in software engineering—from writing code to directing AI systems that write code based on human specifications and intent.
However, Spotify’s approach hasn’t eliminated human developers; rather, it has transformed their role from code writers to code reviewers, architects, and AI prompters.
Engineers now spend more time on system design, user experience considerations, and ensuring AI-generated code meets security and performance standards.
The development community has responded with mixed reactions. Some see this as the inevitable evolution of software engineering, while others express concern about skill degradation and over-reliance on AI systems.
As more companies adopt similar approaches, the definition of “software developer” may fundamentally change.
