About us
We are not a software house
A software house takes an order and builds it. We start one question earlier: what is actually costing you money, how much, and whether building something is in fact the answer. Sometimes it is not — and we say so, even when that means there is no work in it for us.
Digital transformation handled end to end, not in fragments
Established in 2021 under the legal entity PT Digi Harmony Fusion
Focused on AI, automation, Web3, and cybersecurity
Operating under Indonesia’s Personal Data Protection Law and local rules
Core values
Driving business evolution through intelligent technology
Vision
Intelligence built into how the work runs, not bolted onto one department
Most AI deployments end as an experiment in one department and are then abandoned. What we aim for is a system still in use a year later — by your own team, without depending on us.
Mission
Affordable for small businesses, strong enough for large ones
Security that is tested rather than promised. Costs calculated openly, running costs included. And systems whose code and documentation are handed over in full — we lock nothing away.
Four things that set the way we work apart
We start from your numbers
Before a line of code, we measure the hours and the money currently being lost. If the numbers do not justify the build, we say so.
We follow the rules where your data lives
Data protection obligations are treated as a requirement rather than an add-on — including Indonesia’s Personal Data Protection Law for data held there. Where your data may not leave its country, we run the system inside it.
Security tested, not promised
Whatever we build, we attack ourselves first. The findings are handed over unedited.
One team, end to end
From design to the server going live, one party is accountable. You never mediate between vendors.
Does this sound like your organisation?
What is usually costing money before anyone has counted it
If even one of these feels familiar, there is usually a number behind it — and that number can be counted before anything is built.
- 01
Staff spend hours copying and pasting
The same data retyped into several systems every day. The hours are measurable, and usually surprising.
- 02
The systems have never been tested
You do not know a gap exists until someone finds it first — and it is rarely someone friendly.
- 03
Data lives in too many places
Sales in one app, stock in another, notes in a chat group. No single screen anyone trusts.
- 04
Processes depend on somebody remembering
When one person takes leave, the process stops. That is not a process, it is a habit.
- 05
Customers wait too long
Messages pile up at peak hours. Anything unanswered for ten minutes often goes elsewhere.
- 06
The old system cannot be changed
Every small request takes weeks, or the original vendor can no longer be reached.
Our services
Four areas of work that reinforce each other
From AI agents and automation to blockchain contracts and security testing. Most engagements touch more than one area.
Custom Software
Internal applications, dashboards, inventory systems, and company sites — built to be maintained for years, not to demo once.
- Rigid legacy systems replaced without halting operations
- Data scattered across apps finally converges
- Small changes no longer take weeks
Web3 & Blockchain
On-chain contracts, decentralised applications, and token economics — built under strict testing, because mistakes here are permanent.
- Contracts tested and reviewed before they touch real funds
- Revenue-share and fee rules readable by anyone, in the open
- Wallets, payments, and bookkeeping wired into your existing systems
AI Agents & Automation
Assistants that answer customers, agents that finish multi-step work, and workflows that run on their own — with clear limits of authority and a traceable record.
- Customer questions answered in seconds, around the clock
- Multi-step work completed without supervision
- Clear limits on what the machine decides and what escalates to a person
Cybersecurity
Vulnerability assessment, penetration testing, infrastructure hardening, and certification support — reported without varnish.
- Critical gaps found before outsiders use them
- Findings ranked by real danger, not by count
- Compliance evidence ready for ISO 27001, SOC 2, or PCI-DSS
Cybersecurity
Honest findings, not reassuring reports.
Every finding arrives with a reproducible attack path and a remediation step your own team can execute.
- 01
AI System Security Testing
The assistant you deployed can be hijacked. We prove it first. - 02
Fractional CISO
Security leadership without a full-time hire. - 03
Incident Response
Once it has happened: contained, traced, then reported. - 04
Security Engineering
Defences designed, tested, then proven. - 05
Vulnerability Assessment
A complete list of weak points, ranked by real danger. - 06
Penetration Testing
We attack your systems first, before anyone else does.

How we work
You always know which step you are on
The order is the same on every engagement, and each step has an output you can see — not a progress report you have to take on trust.
01
Talk first, at no cost
Tell us what hurts. We listen, then say plainly what is worth building and what is not yet.
02
Measure and design
We produce a plan, a timeline, and a payback calculation. You decide with numbers in hand.
03
Build in the open
You see progress weekly, rather than waiting for a surprise at the end.
04
Test until it can be trusted
We run load tests and attack tests. What is not yet safe is not handed over.
05
Launch and stay reachable
The system goes live, your team is trained, and we remain reachable afterwards.

Questions we are asked most
View allWhat is Neuraltan?+
Neuraltan works across four areas: AI agents and automation, custom software, Web3 and blockchain, and cybersecurity. What is rare is not any one of them but having them in a single team — the systems we build are penetration-tested by the people who know how they were built, and the agents we deploy ship with limits of authority and are tested against instructions slipped in by outsiders.
How do we get started?+
It starts with a one-hour technical session at no cost to map the problem. Where the scope is already clear, we lock a number straight away. Where it is not, we propose a two-week paid diagnosis whose output stands on its own — the specification is yours to take to any vendor, and the fee is credited in full if you continue with us.
How long does an engagement usually take?+
Of the 54 engagements we have on record, 31 finished within two to four weeks. That is the most typical shape of our work, which is why our fixed-price packages sit in that range. Platform builds run two to six months, and ongoing support runs monthly with no fixed end.
How does payment work?+
Payment follows the milestones set out in the proposal, beginning with a deposit before work starts. Invoices fall due within 14 days. We accept bank transfer and digital asset payments in USDT or USDC. All prices exclude tax.
What happens after the work is delivered?+
Defects that depart from the specification are corrected at no charge for 90 days after handover. All source code, documentation, and control are handed over in full — we lock nothing away. If you want us to keep maintaining it, monthly support with a written response time is available; if your team wants to take it over, that was the intention all along.
