Case study

Problem

Marketplace growth usually breaks systems in predictable places: search, listings, checkout, and operational tooling. As volume increases, small inefficiencies compound into user churn and support burden.

Curtsy needed engineering capacity to keep the marketplace running smoothly while continuing to ship improvements, without slowing down growth initiatives.

Solution

Horizon Labs embedded product-minded engineering support to address stability and iteration velocity. We prioritized work that reduced friction in core user journeys and lowered operational overhead for the team.

Outcome

  • Improved reliability across high-traffic flows
  • Faster iteration cycles for product changes
  • Reduced operational burden through targeted tooling and fixes

Features & Tech Stack

  • Marketplace flow stabilization
  • Performance improvements
  • Bug backlog reduction
  • Instrumentation to identify drop-off points
