Riding the unicorn - how Cazoo builds for scale and growth

This event has now ended.
21 October 2021 17:00 - 18:00

Over the past 18 months, Cazoo has gone from being a fledgling ecommerce startup with an ambition to transform the way people buy 2nd hand cars, to today being a multinational automotive retailer, listed on the New York Stock Exchange, valued at $7bn.

As one of the biggest success stories during the pandemic, how has the organisation achieved this phenomenal growth? We are thrilled to welcome Bob Gregory, Chief Architect for Cazoo to this fireside chat where we’ll delve into the technical, organisational and architectural decisions that were made, the rationale behind them, and some of the outcomes that have sustained and accelerated the business as it grows at unparalleled scale.

During the session, we’ll discuss:

  • The Cazoo architecture - why an AWS Serverless Event-Driven paradigm was chosen, the importance of a strong technical vision and how this has helped to guide architectural decisions
  • Platform as a Product - how Cazoo has established Platform teams as enablers for other teams
  • Embracing change (Evolutionary Architecture)
  • Building a successful MVP for an initial launch
  • Architecting for scalability
  • Build vs Buy
  • Using the RFC process (Request for Comments) for internal decision making
  • Building a world-class team - the importance of the right culture, skills and process to maintain velocity and motivation and avoid churn
  • Successful integrations due to acquisition of other businesses
  • Lessons learned
  • What’s next in the evolution of Cazoo
