Spotify: AI-Generated Code Changes Streaming Giant's Tune

Word is, Spotify coders are rocking to the AI jam. 

Gustav Söderström, co-CEO of the streaming platform, revealed during the company's fourth quarter earnings call that Spotify's most experienced developers now spend their time prompting and supervising AI-generated code, rather than writing it themselves.

It is a shift that could represent a fundamental change in how software development operates at scale.

He explained that new tools and model updates released over the holiday period dramatically improved performance, noting that "we crossed the threshold where things just started working".

AI-driven development becomes competitive necessity

The transformation in engineering practices at Spotify could signal broader changes across the technology sector. Gustav emphasised that adopting AI-driven development is becoming essential for companies aiming to remain competitive.

"There is going to have to be a lot of change in these tech companies if you want to stay competitive and we are absolutely hell-bent on leading that change," he says.

"It will be painful for many companies, because engineering practices, product practices and design practices will change."

However, Gustav acknowledged the industry remains in a transitional phase: "The tricky thing is that we are in the middle of the change, so you also have to be very agile. The things you build now may be useless in a month."

Productivity gains outweigh review challenges

While some engineers at other organisations have raised concerns about reviewing large volumes of AI-generated code, Gustav focused on the potential gains in output and speed.

The approach could allow companies to dramatically increase software production, though he noted consumer appetite for change might ultimately become the limiting factor.

"That is the opportunity we see in front of us," he said. "Companies such as us are simply going to produce massively more software. Up until our limiting factor is actually the amount of change that consumers are comfortable with."

Financial results support accelerated ambition

The AI strategy discussion accompanied strong financial performance from Spotify.

According to the company's fourth quarter earnings release, Premium subscribers increased 10% year-over-year to 290 million, while Monthly Active Users rose 11% to 751 million.

Total revenue grew 13% year-over-year on a constant currency basis to €4.5bn (US$5.3bn). Gross margin improved to 33.1%, while the firm's operating income reached €701m (US$829m).

Founder and Executive Chairman Daniel Ek, who stepped back from his position as CEO last year, connected AI adoption to broader technological shifts reshaping media consumption.

"The next wave of technology shifts – AI, new interfaces, wearables, new ways of interacting with content – these will reshape how people discover and experience audio and media," he says.

One of Spotify's two co-CEOs, Alex Norström, indicated that Spotify plans to accelerate its AI integration further in 2026.

"We are framing 2026 as the Year of Raising Ambition," he said, after describing 2025 as the "Year of Accelerated Execution".

Gustav positions Spotify as a testing ground for emerging technologies in the music industry.

"We consider ourselves the R&D department for the music industry," he says.

"Our job is to understand new technologies quickly and capture their potential.

"The entire industry stands to benefit from this [AI] paradigm shift but we believe those who embrace this change and move fast, will benefit the most."
