Software built to stand up to scrutiny.
Apps and AI agents built in Brisbane since 2001 — designed to meet App Store requirements, security reviews, and the Australian regulations that apply to your business. Built to last. Many of our earliest clients are still running software we built for them.

Opportunity knocks
Disrupt or be disrupted.
What we do
From app development to intelligent systems
We build it, take it through review, and keep it running afterwards — the same Brisbane team on all of it, rather than a handoff at each stage. The last part is where most of the work turns out to be.

Mobile & Web Platforms
Scalable products for startups and growing businesses, built native where native matters.
- Native iOS and Android — Swift and Kotlin, not a wrapper
- Tested on real devices, not simulators
- Offline, push, deep links, in-app purchase with server-side receipt validation
- Shipped from your developer account, never ours

AI Agents & Automation
Agents that reason, act and integrate with your systems — not scripted chatbots that only reply.
- Agents that act, not chatbots that reply
- MCP servers and tool integration
- Wired into CRM, booking systems, databases and APIs
- Persistent context across sessions
- Handoff to a human when the agent should stop

Launch Gates
The three barriers a coding tool cannot get you past: store review, security audit, and Australian regulation.
- App Store review — 4.2, 2.5.2, 5.1.1, and Play's 12-tester wall
- Security audit and enterprise security questionnaires
- Australian regulation — which of TGA, Privacy Act, CDR, age assurance and WCAG 2.2 AA you are bound by
- Fixed price, five business days

Built to keep shipping
Software outlives the project that built it. We are still here when the OS changes and the compliance renews.
- Every September's iOS release, handled before it breaks anything
- Target API level bumps before Play enforces them
- Regulatory watch on the rules your app is bound by
- 25 years of it — many first clients are still running software we built


The Founders' Desk
Nathan has been shipping software since 2001; Marisol runs delivery and growth. We are engineers, designers and operators in the same room, and we have sat on both sides of a raise — so the work includes the business model, not only the build.

What clients say
How we build
We’ve built startups ourselves, not only for clients, so the first conversation is usually about your business model rather than your stack. Investor expectations are a different set of questions from user ones, and both get asked here.
We build AI in from the start rather than bolting it on later. Not because it is fashionable — because retrofitting it means rewriting the data model, and that is the expensive kind of rewrite.
What that looks like on a project
- 01
Opportunity Mapping
Sometimes software doesn't pay here. We say so before you spend anything.
- 02
Rapid Validation
A prototype in front of real users before the expensive half starts.
- 03
Build & Integrate
Native where native matters. Shipped from your developer account, never ours.
- 04
Optimise & Scale
We watch what people actually do with it, then cut the features nobody opened.
Selected work
Case studies
A smart diffuser that ended up on The Block. Palliative care education used by healthcare professionals. Strength and running platforms built around community. Fuel pricing at national scale. Cognitive performance for AI-accelerated teams. A productivity timer. And trust infrastructure for AI-built software. Eight products, eight very different problems.
Common questions
- What kind of software does Envisage Apps build?
- Mobile and web platforms, and AI agents that act inside the systems you already run. Then the part most firms leave out: getting a product through App Store review, security audit and Australian regulation, and keeping it shipping once it is out. We also take on MVPs for founders still validating an idea.
- Do you build AI agents, or just add AI features to existing apps?
- We build AI agents and automation — internal tools, customer-facing assistants, workflow automation — as standalone products, and we also embed AI into the UX and decision-making of the apps we build.
- We only have an idea, not a spec. Can you still help?
- Yes — that's MVP and startup acceleration work: validate fast, launch faster, and avoid the cost of building the wrong thing first. We've built startups ourselves, not only for clients, so opportunity mapping and rapid validation come before any code.
- Where is Envisage Apps based, and who do you work with?
- Envisage Apps is a Brisbane and Gold Coast team with 25+ years shipping products, working with founders and established businesses across Australia and globally. Many of our first clients are still using software we built for them years ago, which is the track record we point to rather than a location on a map.
- Do you build games?
- No, Envisage Apps does not develop games. We build business, startup and AI products — mobile and web platforms, AI-powered applications, AI agents and automation, and startup MVPs — so if a games project lands in our inbox, we'll say so up front rather than take the fee.
