A digital studio focused on outcomes
We believe the best digital products are the ones people actually use. Not the ones with the most features.
Jostar grew out of years of freelance work on Fastwork since December 2020 — becoming a top freelancer for mobile app development with 256 completed orders, a 4,8 rating, and a 100% completion rate.
From there, we decided to form our own digital studio with two missions: helping clients build custom products and providing an ecosystem of SaaS tools that serve professionals and small businesses in Indonesia.
Today Jostar builds mobile apps, web apps, and digital tools for clients ranging from startups and SMEs to internal enterprise teams. Jostar's sub-apps (like the Receipt Generator) are already used by many freelancers across Indonesia.
