The Reality

Your MVP worked. But it's held together
with tape and good intentions.

Users love the concept but keep asking for features you don't have. The single-platform limitation is costing you users. The basic backend is creaking. It's time to build the real version.

Users Want More Features

Your MVP feedback is clear — users love the core but want payments, notifications, better search, and deeper functionality. The MVP architecture can't support it all. You need a proper rebuild with room to grow.

Single Platform Limits Growth

Half your potential users are on the other platform. An iOS-only app loses every Android user. A web-only tool misses everyone on mobile. Cross-platform means reaching your full audience.

The Backend Can't Scale

100 users was fine. 1,000 users is slow. 10,000 users will break it. Your MVP backend wasn't built for scale — and rebuilding later costs more than building right the first time.

Common Standard Builds

Validate first

Standard builds are for apps that have proven their concept and need to scale properly.

Full Booking PlatformsMulti-provider scheduling, payments, automated reminders, reviews, and admin management. The complete booking experience across both platforms.
E-Commerce & Marketplace AppsProduct catalogues, shopping carts, secure payments, order tracking, and review systems. Full transactional experiences on mobile.
SaaS PlatformsSubscription-based software with user management, billing, feature gating, and analytics dashboards. Your own software product.
Client PortalsSecure login areas where your clients track progress, view documents, make payments, and communicate with your team.
On-Demand PlatformsReal-time tracking, driver/provider matching, payment processing, and push notifications. The full on-demand experience.
Your Specific BuildEvery Standard build is scoped individually. If your app doesn't fit these examples, that's fine — we build for your exact requirements.

The Process

From validated MVP to scaled product in 8-12 weeks.

We build on what your MVP proved — adding features, platforms, and scale based on real user data.

Review & Plan

We review your MVP data, user feedback, and growth goals. Then we scope the full feature set, platform strategy, and integrations needed. Clear quote and timeline.

Design & Architecture

Refined UI/UX based on user feedback, system architecture design, API planning, and database structure. You approve everything before development begins.

Build & Integrate

Development sprints across all platforms. API integrations, payment setup, admin dashboard, and cross-platform testing. Weekly check-ins throughout.

Launch & Support

Final testing, performance optimisation, and deployment across all platforms. App store submissions, migration from MVP, and post-launch support included.

The MVP Advantage

What a properly built app delivers

Cross-platform reach, proper integrations, scalable infrastructure, and all the features your users asked for. The real product.

Cross-Platform Reach

iOS and Android. Web and mobile. Your app reaches every potential user regardless of their device. No more losing half your audience to platform limitations.

Payments Built In

Stripe, PayPal, or your preferred gateway — integrated properly with secure checkout, subscription billing, and automated receipts. Your app generates revenue from day one.

Admin Control

A proper admin dashboard lets you manage users, content, and settings without developers. You control your app without touching code or raising a support ticket.

API Integrations

Connect to CRMs, payment systems, email platforms, analytics tools, and third-party services. Your app works with your existing business systems, not in isolation.

Built for 100,000 Users

Proper database design, caching, load balancing, and infrastructure that handles growth without breaking. Scale with confidence when the users come.

8-12 Week Delivery

Complex enough to be comprehensive, fast enough to maintain momentum. Weekly sprints with regular check-ins mean you see progress and can adjust priorities as needed.

What Our Clients Say

MVPs that became real products.

From validated MVPs to fully featured, cross-platform products — hear how Standard builds scaled.

"Our MVP booking app had 300 users in the first month, but everyone kept asking for payments and an Android version. Gen6ixx rebuilt it as a Standard Build — cross-platform with Stripe payments, automated reminders, and an admin dashboard. User count tripled in two months."

Amara Kofi

Owner, Flow Yoga Studio

"The Standard build was a completely different level. API integrations with our CRM, a proper admin panel, and push notifications. Our client portal went from a basic web app to a cross-platform product our clients actually prefer over email. Retention is up 60%."

Oliver Brennan

Director, Brennan Consulting Group

"Gen6ixx built our SaaS platform from the ground up — subscription billing, user management, feature gating, and analytics. It launched on web and mobile simultaneously. We went from 0 to 500 paying subscribers in four months. The architecture handles the growth without any issues."

Sam Oduya

Founder, TaskFlow SaaS

Frequently Asked Questions

Everything you need to know about Standard builds.

Standard builds start from £5,000 and typically range up to £10,000 depending on the number of platforms, features, and integrations. A cross-platform booking app with payments might be £6,000-£8,000. A SaaS platform with subscriptions and admin dashboard might be £8,000-£10,000. Every project is scoped individually with a fixed quote.

Not necessarily — but it's recommended. An MVP validates your concept cheaply before you invest in a full build. If you already have clear validation (existing customer demand, proven manual process you're digitising), we can go straight to Standard. We'll advise on the right approach during our discovery call.

iOS (iPhone/iPad), Android, web applications, and progressive web apps (PWAs). Standard builds typically cover 2 platforms — the most common combinations are iOS + Android, or web + mobile. We'll recommend the right approach based on your users.

Yes. You own everything — the code, the design, the assets. If you ever want to take development in-house or to another agency, you take everything with you. No lock-in, no ransom fees.

The MVP build is a one-off project. After launch, you can manage the app yourself or we can provide ongoing maintenance and support on a monthly retainer — hosting, bug fixes, security updates, and minor improvements. We'll discuss this during scoping.

Standard Build (from £5,000) gives you cross-platform development with full features, API integrations, and scalable architecture. Custom Build is for enterprise-level complexity — multi-system integrations, complex business logic, large teams, or specialised technology requirements. Standard handles most apps. Custom handles the exceptional ones.

Websites are informational — they display content and capture enquiries. Apps are functional — they let users do things: book, purchase, track, communicate, manage. If your users need to interact with your platform (not just read it), you need an app. If you need an online presence to showcase your business, you need a website.
