Transforming Operations at Hypergrowth Scale

Role: Head of UX

Timeline: Apr 2021 - Jul 2023

Sector: Automotive Industry

I led UX across 11 product teams during Cazoo's scale to £1bn+ annual revenue—delivering 312% YoY growth, 50% increase in gross profit per unit, and 30% cost reduction through strategic design thinking.

THE CHALLENGE

Stabilizing Cazoo’s core operations

Cazoo was expanding rapidly, growing from a startup to a unicorn in less than two years. However, this fast expansion caused operational disorder: over ten disconnected internal tools, broken handoffs costing millions in post-sale support, and teams unable to see end-to-end workflows. The Operations, Logistics, and Financial Systems domains were the core of the business—when they failed, customers felt it immediately. We needed to unify, optimise, and scale without disrupting a business handling thousands of transactions weekly.

MY ROLE

Rapidly building a team

As Head of UX (Apr 2021 - Jul 2023), I led UX strategy across Operations & Logistics, Financial Systems, and Vehicle Preparation domains, managing eight direct reports (ICs and managers) across 11 cross-functional product teams. I co-owned product strategy with the Heads of Product and Engineering.

THE APPROACH

Strategic moves that shaped outcomes

Repositioned UX research from tactical to strategic

Research was being used to validate features after they were scoped—too late to influence the real problems. I moved the team upstream to identify systemic issues across the entire value chain. This shift uncovered that 36% of post-sale costs stemmed from poor handoffs between systems—a problem no single product team could see. By focusing on strategic research, we started solving root causes instead of symptoms.

Created a north star vision to consolidate 10+ products

Teams were optimising individual tools without understanding how they connected. I led the development of a unified platform vision, providing a framework to prioritise consolidation work and rally stakeholders around shared outcomes. This vision wasn't aspirational—it became our roadmap for phased delivery that balanced innovation with business continuity.

Established end-to-end team ownership

The org structure had teams organised around functions, creating dependency bottlenecks and finger-pointing when things broke. We restructured around complete value streams, giving teams true ownership from start to finish. This single change accelerated decision-making, revealed hidden dependencies, and fundamentally changed what teams could see and solve.

Scaled the domain from 35 to 70+ people in six months

Hypergrowth required doubling the team without losing quality or culture. I created a career framework that gave people clear progression paths, implemented structured hiring that minimized bias, and established rituals that kept culture strong even as we scaled. The result: we achieved the highest retention rate in the entire tech division while hitting aggressive delivery targets.

WHAT MADE IT WORK

Key Learnings

Strategic research justifies itself quickly

Moving research upstream—before features are spec'd—uncovered systemic issues worth millions. The 36% reduction in post-sale costs alone justified the entire research investment and proved to sceptical executives that design thinking drives bottom-line results.

Team structure shapes product outcomes

Reorganising around end-to-end ownership wasn't a process change—it fundamentally changed what teams could see and solve. Structure is strategy. When teams own complete value streams, they naturally identify inefficiencies and opportunities that functional silos miss.

Platform thinking requires patience and political capital

Consolidating 10+ tools wasn't just a design challenge—it required executive alignment, engineering buy-in, and careful sequencing to avoid disrupting live operations. I spent as much time building consensus and managing stakeholders as I did building product. This is the unglamorous work that makes transformation possible.

Culture work isn't soft—it's competitive advantage

In a market competing for the same talent, retention is a business metric. The 34% higher management scores and industry-leading retention didn't happen by accident—they came from intentional investment in career frameworks, transparent communication, and creating space for people to do their best work.
