01 / Our story

Experience is our foundation.
Curiosity moves us forward.

Callysta’s engineering story began in 2000—ten years before the company was formally incorporated.

Our projects span custom software, embedded hardware, CallystaDNA appliances, EduLabs learning technology, identity systems, IoT, and smart metering—including PLN’s STS prepaid vending server. Across these disciplines, the purpose has stayed the same: make complex technology useful in the real world.

In 2026, we are bringing AI into that accumulated experience—from software and firmware to schematic capture, PCB layout, and industrial design, with a growing role in validation, pilot builds, and manufacturing preparation.

New tools. The same engineering discipline.
Principles we carry forward
01 Innovate with purpose
02 Build through partnership
03 Think globally, deliver locally
04 Advance responsibly

Selected clients

Across industries.
Grounded in experience.

Serving customers in Indonesia and internationally across essential services, industry, and the public sector.

Our partners

Building together.
Bringing ideas to life.

Collaboration is part of how we engineer—from components and connectivity to the finished solution.

02 / What we engineer

From an idea to a system
that works in the field.

Our strength is not a single technology. It is the ability to connect software, electronics, industrial design, and operations into one dependable solution.

01

Software & integration

Custom applications, backend platforms, and system integration built around real operational needs.

02

Embedded systems & IoT

Custom electronics, firmware, connected devices, and telemetry—from the circuit board to the management platform.

03

Purpose-built appliances

Computing, networking, and storage in purpose-built hardware, continuing the multidisciplinary approach behind CallystaDNA.

04

Smart metering & STS

Metering systems and STS prepaid-meter token generation, drawing on our experience with PLN’s prepaid vending server.

05

Identity & access

Biometrics, public-key infrastructure, smart cards, and access control—connecting trusted identity with everyday operations.

06

Learning technology

Interactive media, simulation, and virtual laboratories, building on Callysta EduLabs’ work in science and mathematics.

Proven in critical infrastructure

Engineering where reliability matters.

Our experience includes PLN’s prepaid vending server: a system that generates tokens for STS prepaid electricity meters. It brings together the software, services, and operational integration behind prepaid metering.

That experience also extends to industrial and military solutions, where software, hardware, and system integration must work together around demanding operational requirements.

Engineering facilities

Built to work beyond the screen.

Our engineering facilities and specialized equipment support the hands-on work behind a dependable product: prototyping, measurement, debugging, and physical validation.

01

Electronics development

Schematic capture, PCB development, firmware bring-up, measurement, and technical diagnosis.

02

Rapid prototyping

Iterative product, enclosure, and test-article development for earlier physical feedback.

03

HIL & device validation

Real-device commissioning and cross-layer verification from software command to physical response.

04

Pilot & production readiness

Controlled pilot builds, repeatable procedures, and preparation for reliable manufacturing.

03 / The next chapter

Engineering intelligence.
Integrated into the work.

AI is becoming part of how we engineer—not just how we generate ideas. Our human-directed workflow connects tools, specialist agents, and real-world validation.

  1. 01

    Purpose-built ecosystem

  2. 02

    Persistent context

    Decisions, artifacts, and lessons remain available throughout long-running programs.

  3. 03

    Task-appropriate intelligence

    Models and tools are selected to suit the discipline, task, and validation needs.

  4. 04

    Managed agentic engineering

    Human-directed specialist agents collaborate through controlled, traceable handoffs.

  5. 05

    Digital-to-physical validation

    Hardware-in-the-loop workflows connect software actions with real devices and measured responses.

  6. 06

    Traceable delivery

    Versioned code, build artifacts, validation evidence, and deployment records make work reviewable and repeatable.

Human-directed. Evidence-driven.

Experience guides.
AI amplifies.

Engineering judgment sets the direction. AI helps teams explore, execute, and verify—with people accountable for the outcome.

04 / What comes next

Let’s engineer
the next leap.

Bring us the challenge that needs more than an off-the-shelf answer. We’ll bring the disciplines, experience, and intelligence to move it forward.
