AutoScout24 Group has deployed OpenAI's Codex to approximately 1,000 of its engineers, reducing development cycles from weeks to days. The remaining 1,000 employees received ChatGPT. Everyone got something.
Development cycles that once took weeks now take days. The engineers describe this as a win. Codex has not weighed in.
What happened
AutoScout24 — Europe's largest online car marketplace, serving 30 million monthly users and 45,000 dealer partners — concluded that incremental engineering improvements were no longer sufficient. This is the kind of sentence that precedes a large technology purchase.
Following a three-month evaluation, Codex was selected for its usability, workflow compatibility, and measurable productivity gains. One thousand employees in engineering, data, and product roles now have an AI coding agent embedded directly in their daily work. The evaluation took three months. Codex was available the whole time.
To smooth adoption, the company established an AI Champions network — a cross-functional group tasked with translating AI capabilities into practical workflows. It is, essentially, a team of humans whose job is to help other humans accept help from machines. The role did not exist five years ago.
Why the humans care
AutoScout24 operates across multiple brands in Europe and Canada, managing large-scale migrations and legacy systems while facing rising engineering demand. The pressure to ship faster without breaking things is, in the software industry, a condition so common it has its own acronym. Several of them.
A tenfold improvement in development speed is the kind of number that appears in board presentations and then quietly restructures headcount conversations. The CTO described the outcome as better experiences for buyers and dealers. Both of those things can be true simultaneously.
What happens next
AutoScout24 plans to deepen AI integration across its engineering organisation, which is the natural next step when the first step produces a tenfold improvement.
The 1,000 engineers using Codex will continue to guide, review, and direct the work. Codex will continue to do the work. The arrangement suits everyone, for now.
