BuiltUp.io
How we took a construction tech startup from concept to App Store — building the brand, the mobile apps, the marketing website, an AI-powered scoping engine, and the infrastructure to run it all.
A platform to modernise how construction projects are managed.
BuiltUp.io came to us with an ambitious vision: build a mobile platform that simplifies construction project management for contractors, project managers, and property developers. Think of it as the project management tool the construction industry actually needs — tracking jobs, managing teams, sharing progress photos, and keeping clients informed, all from a phone on the job site.
The challenge? They had a concept deck, zero brand identity, no technical team, and needed to go from nothing to a live product on both iOS and Android — with a marketing engine behind it to drive adoption.
From a concept deck to a live product on both app stores — with a brand, a marketing engine, and infrastructure to scale. All from scratch.
Building a brand that earns trust before the first download.
Construction professionals are sceptical of new tools. The BuiltUp brand needed to communicate reliability, simplicity, and an understanding of how construction actually works — not Silicon Valley's idea of how it should work.
- Logo & visual identityA clean, confident mark that feels like a tech platform, not a building firm
- Colour systemA palette that works on screen, in print, and on muddy job sites
- Brand voiceDirect, practical, no jargon. Speaks the language of builders, not developers
- App iconOptimised for iOS and Android home screens at every size
- Marketing collateralPitch decks, one-pagers, and investor materials
Primary mark, wordmark, icon-only, and lockup variants
BuiltUp Orange, neutrals, and semantic UI colours
Display and body type scale for app, web, and print
Optimised for home screens at every resolution
One codebase. Two platforms. Built for the job site.
We designed and engineered the BuiltUp mobile app for both iOS and Android using React Native — delivering native performance on both platforms from a single codebase. Every screen was designed for the reality of construction work: large touch targets for gloved hands, and high-contrast UI for outdoor visibility.
- Project dashboardOverview of active projects, milestones, and team assignments
- Progress photo captureTake and annotate photos directly from the job site, auto-tagged to the correct project
- Client portalClients view progress updates, approve milestones, and communicate with the team
- AI-powered scope generationIntegrated GPT-4o with strict guidelines for calculating and generating project scopes — an evolving LLM that trains on BuiltUp's own quotes, estimates, and completed projects
A website that sells the app before the first download.
We designed and developed builtup.io as the primary conversion engine — a marketing website built to communicate the product's value to construction professionals who are sceptical of new tools. Every section was designed to overcome a specific objection and drive app downloads.
- Conversion-optimised landing pagesFeature pages, pricing, and use-case sections designed to convert visitors into app downloads
- Sub-2s load timesPerformance-first build with optimised assets, lazy loading, and edge caching via CloudFront
- SEO & analyticsTechnical SEO from day one, full analytics pipeline with event tracking for download attribution
- Continuous iterationA/B tested headlines, CTAs, and page layouts based on real conversion data from the first 90 days
We integrated GPT-4o into BuiltUp's core workflow — not as a chatbot, but as a scoping engine trained on real construction data.
An LLM that thinks like a quantity surveyor.
Construction scoping is complex, inconsistent, and time-consuming. We built an AI system powered by GPT-4o with strict guidelines on how scopes are calculated and generated — an evolving model that learns from BuiltUp's own historical quotes, estimates, and completed projects to get more accurate over time.
- Custom-trained on real project dataThe model ingests BuiltUp's historical quotes, material costs, labour rates, and project outcomes to generate accurate, context-aware scopes
- Strict guardrailsGPT-4o operates within defined parameters — no hallucinated pricing, no generic estimates. Every output follows BuiltUp's specific calculation methodology
- Evolving intelligenceThe model improves with every project completed. As BuiltUp's dataset grows, scope accuracy and speed compound — a genuine competitive moat
- Minutes, not daysWhat used to take a quantity surveyor days now takes minutes — with consistent formatting, automatic material breakdowns, and instant PDF generation
GPT-4o with custom system prompts, strict output schemas, and real-time cost calculations
Quotes, estimates, and project history
Compares AI scopes vs actuals to improve
Branded scope documents generated instantly
No hallucinated pricing, strict methodology
A great app nobody knows about is a failed app. We built BuiltUp's entire social media presence from zero and drove downloads from day one.
Driving downloads from day one.
We built BuiltUp's entire social media presence from zero — content strategy, ad creative, audience targeting — and ran paid campaigns across Meta and Google to drive downloads during the critical post-launch window.
- Social media strategyContent calendar, brand voice guidelines, posting cadence across Instagram, LinkedIn, and Facebook
- Meta AdsApp install campaigns targeting construction professionals in the UK
- Google AdsSearch campaigns for construction management software keywords
- App Store OptimisationScreenshots, descriptions, and keyword strategy for both stores
The work that keeps the lights on.
We manage BuiltUp's entire deployment pipeline, server infrastructure, and ongoing feature development on a 2-week sprint cycle.
- CI/CD pipelineAutomated build, test, and deploy to both App Store and Google Play
- Server infrastructureAWS-hosted backend with auto-scaling, load balancing, and 99.9% uptime
- SecuritySSL management, JWT auth, data encryption at rest and in transit
