A software house that stays until the system is in use.
PT Antares Sintesa Digital was founded on 23 April 2023 and builds web applications, mobile apps, and system integrations from our office in Tebet, South Jakarta, Indonesia.
Who we are
Engineers for systems people use every day.
Our work is varied: power grid fault alerts, meeting room reservations at a government office, internet customer payments, and catering operations across several cities. What they share is that people use them every day to get their work done.
Alongside client work, we build and run Kurvas, project and business management software for contractors.

Principles
How we work
- 01
Start from the problem, not the technology
We first understand the workflow and the problem. Technology is chosen after that, to fit the project.
- 02
Something to try at every stage
Work is split into stages. You see and try the results from the start, not only at the end.
- 03
Still involved after launch
A system in use needs care. We keep handling fixes, security, and new features.
- 04
We run our own product
We build and operate Kurvas, so we know what it takes to maintain software that is used every day.
Technical experience
Things we have already built.
AI assistants built on Claude
Asisten Kurvas uses Claude by Anthropic to read company figures, draft budgets and quotes, and propose actions that only run once the user confirms them.
Systems that work without internet
Offline-first apps for PLN field teams that sync when the connection returns.
WhatsApp and Telegram integration
Power grid fault alerts, document approvals, and customer service.
Operational and sensor data
SCADA, LiDAR, and transmission dashboards for engineering decisions.
Payments and accounting
Xendit and MikroTik for ISP customers, and Jurnal Mekari for catering accounting.
How we work
Clear before we start, involved until the end.
Step 1
First consultation
A free session by phone or WhatsApp. We listen to the problem first, with no obligation.
Step 2
Estimate and contract
You receive a time and cost estimate. Scope, schedule, and price are written into the contract before work starts.
Step 3
Development in stages
Work is split into stages you can try at each step. Payments follow milestones.
Step 4
Launch and support
Once the system is live, we keep handling fixes, security patches, and new features. Monthly or on-demand plans are available.
