Just Eat Takeaway (JET) is one of the world’s leading global on-demand delivery companies, supporting over 2,000 people (many engineers) across 300 teams and more than 3,000 services (features). Like many fast-growing tech companies, JET’s infrastructure complexity expanded rapidly through multiple acquisitions, resulting in a fragmented environment built on legacy systems and inconsistent cost management practices.
Operating primarily on AWS, with select GCP usage for analytics, JET’s FinOps journey began with a critical need: create visibility, consistency, and accountability across a decentralized and fast-moving organization.
With thousands of services running on AWS, JET faced mounting issues in attributing spend, managing cost governance, and driving collaboration across engineering teams. Due to acquisition-related fragmentation, many applications were tagged inconsistently, or not at all. Even with centralized FinOps efforts, nearly half of AWS spend remained unallocated.
Moreover, previous tools lacked usability. Dashboards were difficult to navigate, time-to-insight was long, and adoption was extremely limited. Engineers found existing platforms unintuitive, and even the FinOps team struggled to gain clarity from them.
“We weren’t facing a visibility issue. It was an ownership and consistency issue across the organisation”
Carlos Galán | Cloud FinOps Lead
JET needed a platform that could scale with its engineering culture, work across AWS, and provide an immediate path from insight to action.
Finout offered the usability and flexibility JET required. The FinOps team rolled out a standardized dashboard model, allowing teams to clone pre-built views and immediately take ownership of their cloud costs. This led to an exponential increase in adoption—from under 40 users to more than 700 engineers engaged in FinOps practices.
“Once we had confidence and mastery in Finout, it became much easier to spread the message internally”
Carlos Galán | Cloud FinOps Lead
At the core of this transformation was the Virtual Tagging API. Finout’s dynamic allocation engine allowed JET to attribute costs daily across teams and services to account for shifts in organisational structures, even without perfect tagging—a critical capability in an infrastructure shaped by legacy systems.
“Virtual Tags are the foundation of everything we do. They let us organize spending in a way that’s easy to understand, even without ideal tagging ”

Finout’s MegaBill & Data Explorer features enabled fast, self-serve exploration and storytelling. Engineers could filter spend by service or time period and understand performance, while leadership received clear visibility into what’s growing, what’s optimized, and why.
“We’re no longer fighting fires. We’re getting ahead of spend and shaping behavior before things go off course”
Kim Wilson | Senior Cloud FinOps Analyst
By implementing Finout, JET:
Crucially, the clarity provided by Finout allowed JET to scale more confidently on AWS. With greater understanding of what was driving spend, from disaster recovery investments to new services, leadership was able to support increased cloud usage without concern of hidden inefficiencies.
“It gives you confidence that the optimization you’re pushing for is actually happening—because now you can see it clearly”
Carlos Galán | Cloud FinOps Lead
Financial planning is also becoming a cornerstone of JET’s culture. With departmental forecasts now piloted using Finout, with the aim to enhance accountability through a shift-left approach.
“Finout has enabled us to present insights to leadership and engineering in a way we couldn’t before. That has had a huge impact”
Kim Wilson | Senior Cloud FinOps Analyst
JET is continuing to evolve its FinOps maturity, focusing on:
As Finout becomes embedded in day-to-day operations, JET is shifting from a reactive approach to proactive cost management. Engineers, empowered with data, are making better decisions. Leadership, supported by insight, is investing smarter.
What began as a tooling change has turned into a foundational shift in how Just Eat Takeaway.com sees, manages, and grows its cloud infrastructure.
"Leadership sees the numbers and understands the story. That gave them confidence to support our AWS growth, because the increases are backed by data, not assumptions"
