OneZero Software House
Your dreams.
We code it.
Whatever it is you need in tech/digital.
We don't say no.
We ship.
// Who we are and who it's for
A software house that builds apps, software and digital products — from the first spec to production.
Startups and companies with a product or a development budget, an in-house team that needs reinforcement, or a product that has to move on from a previous team. Three ways to start:
- 01
Build a new product
An iOS and Android app, a web system or a SaaS product — one team for spec, design, development, QA and launch.
App developmentSoftware & systemsExample: Mystorya — an iOS, Android and web app built end to end
- 02
A team that joins your product
A development team that joins an existing product or starts it from day one, works alongside the founders and scales with the need.
Startup development teamProject or team? The guideExample: OneAI — five years as the technology partner, through to the acquisition
- 03
Continue or rescue an existing product
Code written by a previous team, a legacy system that needs gradual modernisation, or an MVP built with AI tools that has to reach production.

# OUR WORK
From a spoken idea
to a 3D model.
A SketchUp extension that turns natural language into geometry and lets you keep developing the model in conversation.
Typography
at the centre.
A Hebrew font catalogue with live preview, purchase and a typography magazine.
All the business knows.
In every employee's hands.
Organisational AI chat, tasks and procedures — on mobile and in one management system.
The service
comes to you.
On-demand mobile services by location, with customer and driver apps and real-time tracking.
A store built
around the brand.
A shopping experience in three languages,
from the collection to checkout and delivery.
And many more.
Every project in one place.
Apps, platforms and systems we built end-to-end — each linking to the live product or the full build story.
