Slice: 85 Percent Faster App Launch and 25 Percent Order Lift with Cold-Start Optimization
Challenge
Slice - Order Local Pizza faced 6.4-second cold app launches, UI stalls on menu load, and sub-benchmark conversion rates, driving high drop-off and $120k annual support costs.
Solution
Softaims architected a cold-start launch and main-thread decoupling solution for Slice, leveraging pre-compiled modules, Rust-powered bridges, and skeleton UI shells to deliver a seamless, sub-second user experience. The phased 16-week delivery achieved a dramatic speedup, cost savings, and improved user retention.
Result
Cold start latency reduced from 6.4s to 950ms (85% improvement)
