Case Study · Ride-Hailing

SIDASafe is a women-first ride-hailing ecosystem we designed and built.

SIDASafe is a ride-hailing ecosystem we built for PT Sida Berjaya Energi, focused on safety and comfort for women: a rider app (SIDAsafe), a companion app (SIDAbestie) and a driver app (SIDAroyal) for a female-driver fleet, live on both iOS and Android.

Is it live on the App Store and Google Play?

Yes. The SIDA apps are published on both the App Store and Google Play, with 20,000+ downloads across the ecosystem.
