We build the software your next stage of growth runs on.
OneScale Studio designs and builds custom software, AI systems, and mobile products for startups and businesses — scoped honestly, shipped in weeks, and handed over in a state your team can actually maintain.
Why we exist
Most businesses that need custom software end up choosing between a slow enterprise vendor and a freelancer who disappears after launch. We built this studio to be the option in between.
We scope before we build
A fixed proposal with a real timeline and price, before any code is written — not an open-ended hourly clock.
We build to be maintained
Documented, ordinary code your future in-house team can read — not a clever system only we can touch.
We stay after launch
Every project ships with a support window, and most clients keep us on retainer for what comes next.
What we build
Four services. One team you brief once.
Hire us for one project or lean on us as your ongoing engineering team — the scope changes, the way we work doesn't.
Custom software & web platforms
We design and build the software your business runs on — customer-facing products, internal tools, and full SaaS platforms — with an architecture that holds up as you grow, not one you'll have to rebuild in a year.
- Product strategy and technical scoping before a line of code is written
- Web applications built on modern, maintainable stacks
- Internal tools and dashboards that replace spreadsheets and manual work
- API design and third-party integrations
Example brief
A subscription-box startup needed a customer portal to manage plans, pause deliveries, and view invoices without emailing support. We scoped, designed, and shipped it as a standalone web app connected to their existing payments provider.
AI systems & workflow automation
We build AI that does something, not just answers questions — customer-support agents, internal copilots, and automations that connect your tools together and complete tasks without a human doing them by hand.
- Custom AI agents for support, sales, and internal operations
- LLM integrations with your product or internal systems
- Workflow automation across the tools you already use
- Retrieval and knowledge-base setups so answers stay accurate
Example brief
A B2B services company was answering the same 20 questions over email every day. We built a support agent trained on their documentation that resolves routine questions and routes anything unclear straight to their team.
Mobile applications
We build mobile apps that hold up past launch day — clean architecture, a design your users understand instantly, and a release process your team can maintain without us in the room.
- Cross-platform apps for iOS and Android from a single codebase
- Interface design centred on the two or three things users do most
- Push notifications, offline support, and in-app payments where needed
- App Store and Play Store submission handled end to end
Example brief
A neighbourhood laundry service needed customers to book pickups and track order status from their phone. We built and shipped the app in eight weeks, integrated with their existing order system.
Enterprise systems & data platforms
When spreadsheets, disconnected tools, and ageing systems start slowing a business down, we untangle it — connecting what you already have, migrating what needs to move, and building the data platform underneath it.
- Legacy system audits and modernization roadmaps
- Integrations between CRMs, ERPs, and internal tools
- Data pipelines and reporting platforms
- Migration planning with minimal downtime
Example brief
A distribution business ran inventory in one system and orders in another, reconciled by hand each night. We built a sync layer between both and a dashboard that shows stock and orders in one place.
How we work
Six steps, the same order, every project.
No surprises about what happens next — you know exactly where a project stands at every stage.
See the full process- 01
Discovery call
A focused conversation about what's broken, what you're trying to achieve, and who the software is actually for. No sales pitch — we ask questions until the problem is clear.
- 02
Scope & proposal
You get a written scope of work, timeline, and fixed price before anything is signed. If something's unclear, we run a short paid discovery sprint rather than guess.
- 03
Design
Screens, flows, or architecture diagrams — whatever the project needs — reviewed with you before development starts, so changes happen on paper, not in code.
- 04
Build
Development happens in short cycles with a working preview you can check in on, not a single black-box delivery at the end.
- 05
QA & launch
Testing against real devices and real data, a staged rollout, and a launch day where we're on call in case anything needs attention.
- 06
Support & growth
Every project includes a fixed support window after launch. After that, most clients move to a monthly retainer for updates, new features, and maintenance.
Who we work with
Wherever your business is, there's a way to start.
Early-stage startups
You need an MVP that's good enough to raise on or sell with, built fast.
- Fixed-scope MVP builds
- Technical co-founder-style guidance
- Built to hand off to an in-house team later
Growing businesses
Manual processes and spreadsheets are starting to cost you real time.
- Internal tools that replace manual work
- Integrations between the tools you already use
- AI automation for repetitive tasks
Established companies
You have systems in place but need something specific built or connected.
- Legacy modernization and migrations
- Custom internal platforms
- Ongoing engineering as a monthly retainer
