Vinted sees 58% increase in PR throughput with DX
Vinted, Europe’s leading secondhand fashion marketplace, has always treated engineering productivity as a strategic advantage to remain ahead of its competitors. However, as the company’s engineering organization grew, it became more difficult to identify sources of friction across the developer workflow. “When you have a smaller team, you can fix problems very organically by discussing what they are as a group,” explains Mindaugas Mozūras, CTO. “When we grew, staying close to the problems impacting teams became a challenge. We realized we needed more comprehensive data to understand the situation better and to make informed decisions on where to invest.”
A DevEx team was formed with a stated goal to find better ways to measure productivity and to make well-informed improvements that reduce friction across the software development lifecycle. The DevEx team was already familiar with DX—and by partnering with DX early in their journey, they gained access to a deep stream of qualitative developer insights, cross-referenced with engineering metrics in DX’s developer insights platform to clearly identify where improvements should be made. That early integration shaped how DX is used, not only as a reporting layer, but as a foundation for how leaders and teams reason about engineering productivity, investment, and impact.
Today, DX is used at all levels of Vinted, from senior executives to platform engineers to engineering managers, each viewing the data through a different lens. “I use DX to get a better understanding of what’s going on,” Mozūras says. “What engineers are happy with, unhappy with, what’s working, what’s not working, where they are productive, where they are unproductive. That informs my decisions on what to invest in, what kind of tools to build, how much time to invest into tackling tech debt versus building features.”
That understanding becomes especially valuable in leadership forums. Mozūras recently used DX data in a quarterly group leadership meeting to evaluate the impact of a major internal initiative. “One investment we’re doing is a program called modularization,” he explains. “Because of the data I have from DX, I can show in both quantitative and qualitative ways that our initiative improved the productivity of our engineers, and I can explain why that investment made sense to my very senior stakeholders,” Mozūras adds. “As a CTO, that is incredibly valuable.”
At the platform engineering level, DX helps make the impact of the platform team visible to leadership. “Our Engineering Experience group builds for developers, which makes the impact of our work harder to quantify,” says Paulius Raškevičius, a manager on the Engineering Experience domain. “DX enables us to show our impact. It also helps us show that the problems we’re solving for aren’t something we imagined—engineers are telling us where time and impact are being lost.”
Another aspect in which DX helps Vinted is evaluating the impact of AI on software development, where DX has become the system of record for both usage and outcomes. Engineers use Cursor, Claude Code, and GitHub Copilot, and DX tracks how that adoption translates into productivity gains. “We’re careful to separate correlation from causation,” Mozūras says. Raškevičius adds: “A roughly 10 percent throughput gap shows up between non-users of AI, and heavy users, but there’s a valley in between. One insight for us was that light adopters can be less productive than non-users, but daily use drives gains.” The focus has shifted from whether to adopt AI to how best to support teams through the learning curve.
Since using DX, Vinted’s average PR throughput has increased from 1.4 PRs/eng per week to 2.4 PRs/eng per week, but for Mozūras, the most meaningful signal comes from how engineers describe their own experience. “When we look at our qualitative delivery metrics, one signal stands out. We regularly ask engineers how fast they feel the team is shipping, with options ranging from slow to very fast. That data shows a clear shift. Engineers consistently feel we are delivering faster today than we were two years ago.”
As Vinted enters its next phase of growth, DX has become the central source of truth for engineering performance and improvement. Mozūras states, “DX is how we measure whether we are making progress toward our goals. As we invest in productivity, modernization, and new tools, DX helps us see what is working through both quantitative and qualitative signals. That informs our decisions, guides where we adjust, and gives us confidence that we are moving in the direction we expect.”
