Case Study: Flipkart achieves 45% faster app startup with HeadSpin (NimbleDroid)

How Headspin And Nimbledroid Helped Flipkart Speed Up App Startup By 45%

Flipkart, India’s leading e‑commerce company, faced a critical performance challenge: slow mobile app startup times that risked revenue, app-store rankings, and user abandonment. HeadSpin’s NimbleDroid was engaged to diagnose and address these startup bottlenecks across Flipkart’s Android codebase.

NimbleDroid (a HeadSpin company) pinpointed costly GSON reflection during JSON parsing and guided Flipkart to eliminate reflection (using generated Type Adapters via Vimeo’s Stag and other fixes), caught two regressions before release, and removed unnecessary lazy initialization. The result: a 45% reduction in app cold startup time (to about 2.2 seconds), measurable competitive lead in benchmarks, and improved reliability for millions of users — all delivered by HeadSpin.
