We build custom software for your agency’s clients.
Z9 Development is a small, senior, AI-assisted engineering team. We scope, architect, build, and maintain custom web applications, and the work ships in your agency’s name. You own the source code.
Custom applications, shaped around the business.
Two decades of building real systems across very different industries. Every project starts with understanding how the client actually works.
E-commerce sites
Storefronts and checkout built around how the business actually sells.
Company brand stores
Branded online stores, one per client, run from a single system.
Multi-channel order fulfillment
Order and inventory systems that sync across many sales channels.
Content management sites
Sites your clients can update themselves, with a CMS when one is needed.
Online training and compliance
Learning platforms that track training and compliance across organizations.
Event management systems
Registration, scheduling, and event operations in one place.
Marketing and sales integrations
Connecting CRMs, customer data platforms, and the tools your clients run.
Custom apps with AI
Applications with AI built in where it adds real value, not as a gimmick.
Prototypes and SaaS replacements
Working prototypes and POCs, and custom replacements for SaaS a client has outgrown.
An AI-assisted senior team, start to finish.
Senior people, AI-assisted
A small senior team uses AI to move quickly. Senior judgment makes sure what ships holds up in production.
We start with the business
You do not need a finished spec. Helping define the right thing to build is where we add the most value.
You work with the builders
No account managers and no junior hand-offs. You work directly with the people writing your software.
Most engagements start small, often a working prototype we can stand up quickly. We bill hourly, or quote a fixed price once the scope is clear, with no long-term retainer.
Built on Z9 Engine, our rapid development framework.
Z9 Engine is the rapid development framework we have been building and refining since 2004. It is why a small team can ship production software quickly and keep it running for years, and it is behind everything we build.
Faster builds
A mature framework means we are not rebuilding the basics on every project, so more of your budget goes to what makes the app unique.
Fewer surprises
The foundation has been refined since 2004 and runs in production every day, so there is less that can go wrong.
Content management when needed
A CMS we drop in when a project calls for one, so your client can manage their own content.
- Source code delivered with every build. The application we build is yours to keep.
- A perpetual Z9 Engine license is included with every build, at no recurring cost.
- No vendor lock-in. The Z9 Engine framework is standard PHP and MySQL, so you or another developer can maintain it.
Z9 Engine is our rapid development framework. Z9 Platform is the separate, optional service that hosts and operates what we build. A Z9 Engine app can run anywhere you choose. See Z9 Platform
