Zero One is a software house based in Surabaya. We design and build custom business systems, web and mobile applications, ERP, and private AI around the way your organization actually operates — then hand over the full source code on a server you own.
Custom software fails when the people building it never see the work it is meant to support. Being in the same city makes that far less likely.
Warehouses, clinics, factory lines, and back offices are easier to model when you can stand in them. Being in Surabaya means workshops and walkthroughs happen in person, in the same week, not over a scheduling gap.
Questions get answered the same working day. We run projects in English or Indonesian, so the people who know the process best can describe it in their own words instead of through a translation layer.
A system is not finished at launch. The team that built yours keeps maintaining and extending it, and remains reachable long after the project closes rather than rotating off to the next account.
Local, not limited to local. Zero One delivers software and AI across Indonesia and South East Asia, and clients outside Surabaya run entirely on remote collaboration.
One team handles discovery, architecture, build, deployment, and support — so nothing is lost in a handover between vendors.
Accounting and finance, CRM, document management, HR, property management, production and MES, warehouse and inventory — built from the ground up around your process instead of forcing the process into a template.
Browse the full system listBrowser-based systems your team can reach from any office or site, with role-based access, reporting, and dashboards that turn operational data into decisions rather than another export to reconcile.
Native Android and iOS applications for field teams, drivers, sales, and care staff — connected straight to your core systems so what happens outside the office is visible inside it.
Finance, inventory, production, and people management joined into one system, with the approvals and handoffs that currently live in chat threads and spreadsheets moved into the workflow itself.
Customized AI assistants trained on your own documents and records, running on your server or private cloud. Nothing is sent away to train a third-party model — the privacy is structural, not a policy promise.
How private AI worksConnecting storefronts, mobile apps, and back-office systems so data flows once instead of being re-keyed, plus continuous maintenance and enhancement as the business changes.
Your code, your serverMost projects start from the same place: the business changed, and the software did not follow.
Zero One has delivered systems and AI for clients across these sectors:
Organizations handling confidential records — legal, healthcare, finance, HR, and government — are also where our private, on-premise AI work is concentrated.
Four stages, one team, no handover to a party that was not in the room.
We map the operation as it is: who does what, where the exceptions live, and what the system has to get right to be worth using.
Architecture, data model, and interfaces are designed against that map, so scope is agreed on something concrete before the build starts.
Development proceeds in reviewable increments. Your team sees working software and corrects course while corrections are still cheap.
We deploy to your dedicated server, train the people who will use it, hand over the source code, and stay on for maintenance and enhancements.
Zero One has been building custom software since long before the current wave of AI tooling. That history is what the AI work is built on.
A selection of the organizations we have partnered with.
A software house designs, builds, and maintains software for other organizations instead of selling a fixed off-the-shelf product. Zero One covers the full cycle from one team in Surabaya: mapping your business process, designing and building the system around it, deploying it to your own dedicated server, and supporting it long term.
Custom business systems and web applications such as accounting and finance, business intelligence, CRM, document management, ecommerce, asset and fleet tracking, home care systems, human resource, property management, production and MES, and warehouse and inventory. Zero One also builds native Android and iOS applications connected to those systems, and private AI assistants that run on your own infrastructure.
Yes. Zero One is based in Surabaya, East Java, and delivers software and AI across Indonesia and South East Asia. Projects run in English or Indonesian, and remote collaboration is standard practice for clients outside the city.
It begins with discovery. We map how your business actually works, including the workflows, the edge cases, and the goals behind the request. That produces a shared picture of scope and architecture before any code is written, so what gets built matches the operation rather than a generic template.
Yes. Systems are built to connect rather than to stand alone. Typical work includes wiring storefronts and order pipelines into the back office, connecting mobile applications to core business systems, and bringing separate tools into one flow of data so a number only has to be entered once.
Yes. The same team that builds your system stays on it, providing continuous maintenance and enhancements as the business changes. Long term support and enhancement is part of how Zero One works, not a separate handover to another vendor.
Cost follows scope, and scope comes out of discovery. Because every system is built around a specific business process, there is no fixed price list. Tell us the outcome you are after and we will come back with a scope and a figure for that scope.
Describe the operation and the outcome you are after. We will come back with how we would build it, what it would take, and whether we are the right team for it.
Thanks — we'll be in touch shortly to talk through your project.
