Case Study: Speedway Motors boosts conversions and accelerates experimentation with Harness

Speedway Motors Accelerates Innovation and Customer Conversion with Harness Feature Management & Experimentation

Speedway Motors, a tech-enabled retail and e-commerce company serving automotive enthusiasts, was struggling with risky two-week release cycles, late-night deployments, long feedback loops, and limited visibility into production issues. To reduce release risk and support faster innovation, Speedway turned to Harness Feature Management & Experimentation.

With Harness, Speedway Motors moved to safe progressive delivery and controlled experimentation, rolling out features gradually, monitoring performance, and quickly turning off flags if needed. Harness helped the team increase deployment frequency to multiple times per day, cut rollback time to about 20 seconds, run 5–10 experiments per sprint, and achieve measurable business gains including a 30% increase in mobile conversion, a 5.5% lift in purchase attribution from search, and a 4% increase in total orders placed.
