The problem
Most app projects either cost too much, cut too many corners, or leave you dependent on the team that built them.
The bloated agency route
Layers of account management, long timelines and a bill that reflects the agency structure as much as the software.
The cheap build route
Looks finished until real users arrive. Weak architecture, rushed UX and a codebase nobody wants to inherit.
The platform-lock-in route
Fast at the start, restrictive later. The moment the product needs custom logic, deeper integrations or scale, the ceiling appears.
What we build
Web apps. Mobile apps.
SaaS platforms. Marketplaces.
Product strategy, UX/UI and engineering are handled together. The result is a production product rather than a prototype passed between disconnected suppliers.
Mobile apps
iOS and Android products built with React Native and Expo.
Web apps
Production web applications built with Next.js, React and TypeScript.
SaaS products
Accounts, subscriptions, dashboards, permissions and operational tooling.
Marketplaces
Listings, search, accounts, enquiries, payments and multi-sided workflows.
Production experience
We build software that is meant to go live and keep evolving.
Wall & Fifth works across mobile applications, web products, SaaS platforms, marketplaces and custom business software. The common thread is production: real users, real data, real integrations and software that has to keep working after launch.
We also build and operate our own software products, so decisions around scope, architecture, launch, product iteration and maintenance are things we make on our own account as well as for clients.
The first decision
Web, mobile, or both?
Start with web
When reach, discoverability, sharing and instant access matter more than installation or device-native behaviour.
Build mobile
When the product is used frequently, benefits from notifications, lives on the move or needs device capabilities.
Build both
When the same product genuinely needs the accessibility of the web and the repeat engagement of a mobile app.
Pricing
Fixed price. Clear scope. No surprises.
A defined build for a defined price. The scope is agreed before development begins.
A focused production application with the essential flows, integrations and launch-ready product experience.
Larger products with multiple user types, richer functionality, integrations, complex admin and broader platform requirements.
Process
From idea to production product.
How we work
Not an app factory.
A senior product and engineering team.
Think before building
Scope and product decisions are treated as part of the build, not paperwork before it.
Real engineering
Production software rather than a configured template or rented app-builder.
Built to continue
Architecture intended to survive launch, real users and continued development.
Ownership on delivery
The software, source code and associated IP are handed over.
Built across categories
Different products. The same production standard.
Mobile products
Apps for iOS and Android, including product design, engineering and launch.
Web platforms
Custom web applications, portals, dashboards and business-critical workflows.
SaaS products
Subscription products with accounts, billing, permissions and operational tooling.
Marketplaces
Platforms connecting multiple user groups through listings, search, enquiries and transactions.
