Case Study | Online Marketplace Black Friday

Spike - Who we are

For an online marketplace Black Friday brings a critical need to protecting their brand and partners – this was vital for our client NotOnTheHighStreet ahead of their 2020 peak trading period.

Could they live up to their own high standards, even with COVID-19, lockdowns, and peak surges? In short, yes.

Spike performance insights built confidence in their systems ahead of peak trading, smash their targets and ensure they were ready for future sales surges.

Lockdowns Brought Unique Challenges

COVID-19 gave our client a real challenge – could their business model cope with the surge and adapt to the growing ‘Gifting-as-a-Service’ market?

The Risk of Failure Was Too Big to Ignore

  • Downtime would cost £250k per hour
  • Failure would shred their hard-earned reputation
  • Sustained outages would cripple their 5000 partners


  • Establish an accurate workload model
  • Create reusable performance testing assets
  • Identify any performance issues and highlight areas of concern
  • Provide confidence for their peak sales period

The Spike Performance Methodology – Rapid and Rock-Solid
