Why Spotify Senior Engineers are Handing the Keyboard to AI

Spotify's senior engineers aren't coding, as they step away from the keyboard for AI.

Spotify’s Co-CEO Gustav Söderström says the company’s most senior developers have largely stepped away from manual coding, shifting instead to guiding AI systems that generate and refine code instead.

Speaking on Spotify’s fourth-quarter earnings call, Gustav framed the change not as a drop in performance, but as a new peak in productivity.

“When I speak to my most senior engineers, the best developers we have, they actually say that they haven’t written a single line of code since December,” he said.

“They actually only generate code and supervise it.” 

Gustav described the recent holiday period as an inflection point for AI-assisted development, a moment when model upgrades and new tools “crossed the threshold where things just started working”.

The result: engineers moving from typing line-by-line to prompting, reviewing and steering high-quality AI output.

AI at the centre of strategy

Spotify's Co-CEO positioned AI-driven development as core to Spotify’s competitive strategy and a catalyst for industry-wide change.

“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,” Gustav said.

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

An inevitable transition for companies

Gustav cautioned that the transition is ongoing and fast-moving.

“The tricky thing is that we’re 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.”

While some engineers worry about reviewing large volumes of AI-generated code, Spotify sees the upside in speed and volume.

“Companies such as us are simply going to produce massively more software,” Gustav said.

“Up until our limiting factor is actually the amount of change that consumers are comfortable with.”

Co-CEO Alex Norström signalled the company will accelerate further in 2026, calling it “the Year of Raising Ambition” following 2025’s “Year of Accelerated Execution”.

Strong Q4 performance

The AI discussion accompanied solid quarterly results. In Q4 2025, Spotify reported Premium subscribers up 10% year over year to 290 million, Monthly Active Users up 11% to 751 million and total revenue up 13% year over year on a constant-currency basis to €4.5bn (US$5.3bn).

Gross margin improved to 33.1%, and operating income reached €701m (US$829m).

Founder and Executive Chairman Daniel Ek tied the company’s AI push to broader shifts in media and interfaces.

“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 said.

Research and development for the music industry

Gustav Söderström cast Spotify as a fast-moving test bed for the sector.

“We consider ourselves the R&D department for the music industry. Our job is to understand new technologies quickly and capture their potential,” he said.

“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.”
