30-Day MVP Development Sprint
From App Idea to Production Launch in 30 Days
Your Idea Deserves More Than a Slide Deck
You've got a validated concept. Maybe some wireframes, maybe just a napkin sketch. What you need is working software — deployed, functional, and ready for real users to sign up, pay, and tell you what they actually think.
Our 30-Day MVP Sprint takes your app from zero to production at a fixed scope, fixed price. No hourly billing surprises. No scope creep. No six-month timelines that burn through your runway before you've learned anything useful.
We build with Next.js, Supabase, and Vercel — the same stack powering companies at Series A and beyond. You get production-grade code, not a prototype held together with duct tape and good intentions.
Why a 30-Day Sprint Works
Most MVPs fail not because the idea is bad, but because founders spend too long building the wrong thing. A 30-day constraint forces brutal prioritisation. You launch with 2-3 core features that actually matter, get real user data, and iterate from there.
Here's what we see consistently:
- Founders who launch in 30 days get investor conversations faster because they have traction metrics, not pitch decks
- Fixed scope eliminates decision fatigue — we agree on exactly what gets built before a single line of code is written
- Fixed price eliminates financial anxiety — you know the total cost on day one, not day ninety
Traditional agencies quote £80K-£200K and 6-12 months for what we deliver in 30 days. That's not because they're building something better. It's because they're building something bigger than you need right now.
Our Approach: Week by Week
Week 1: Scope, Design, and Architecture
Before we write code, we nail the scope. Honestly, this is the most important week of the entire sprint.
- Discovery session (60-90 minutes): We map your user journey, identify the 2-3 features that prove your hypothesis, and ruthlessly cut everything else
- Wireframes in Figma: You see every screen before we build it. Non-technical founders can point at things and say "that's not right" — and we fix it before it costs real time
- Database schema and API contracts: We design the Supabase data model, define authentication flows, and map third-party integrations
- Written scope document: You sign off on exactly what gets built. This is the contract. No ambiguity.
Week 2-3: Build Sprint
This is where the stack earns its keep.
Next.js with App Router and Server Components gives us:
- Server-side rendering for SEO and performance
- TypeScript throughout for type safety and fewer bugs
- React Server Components for secure data fetching without exposing API keys
- Sub-100ms page loads on Vercel's edge network
Supabase replaces weeks of custom backend work with production-ready infrastructure:
- PostgreSQL database with row-level security — your data is locked down from day one
- Authentication (email, Google, GitHub, magic links) deployed in hours, not weeks
- File storage with CDN for user uploads
- Real-time subscriptions if your app needs live updates
- Edge Functions for server-side logic
Vercel handles deployment and scaling:
- Git-push deploys — every commit gets a preview URL you can actually click through and test
- Global edge network with automatic scaling
- Zero DevOps overhead for you, ever
We use AI-assisted development (GitHub Copilot, Cursor) to accelerate routine implementations by 40-60%, then spend that saved time on the complex business logic that actually differentiates your product.
Week 4: Test, Polish, Launch
- QA testing across devices and browsers
- 5-user testing sessions that catch 80% of UX issues
- Performance audit: Core Web Vitals optimisation, Lighthouse scores
- Production deployment on Vercel with custom domain, SSL, and monitoring
- Analytics setup: We wire in the tracking you need to measure what matters (signups, activation, retention)
- Handover documentation: README, environment variables, deployment guide
You launch on day 30 with a URL you can send to users, investors, and your mum.
What You Actually Get
Every 30-Day MVP Sprint delivers:
- Production-deployed web application on Vercel with custom domain
- Full source code — you own 100% of it, no licensing, no lock-in
- Supabase backend with authentication, database, and storage configured
- Stripe integration if your MVP needs payments (SaaS subscriptions, one-time purchases, or marketplace transactions)
- Responsive design that works on mobile, tablet, and desktop
- SEO foundations — meta tags, Open Graph, structured data, sitemap
- 30 days of post-launch support for bug fixes and minor adjustments
- Technical documentation so your next developer (or your future CTO) can pick up where we left off
Who This Is For
Our 30-Day Sprint is built specifically for:
- Non-technical founders who need a technical co-founder's output without giving up equity
- Pre-seed and seed startups who need traction metrics before their next raise
- Solo founders with a validated idea and £5K-£25K to invest in getting to market
- Corporate innovation teams testing new product concepts outside the main roadmap
We work with founders across the UK, London, and the US. Timezone overlap matters — we schedule standups and demos during your working hours, whether that's GMT or EST.
What We Won't Build in 30 Days
Transparency matters more than winning a sale. Here's what doesn't fit a 30-day sprint:
- Multi-sided marketplaces with complex matching algorithms (45-60 days minimum)
- Apps requiring custom ML/AI model training (we can integrate existing APIs like OpenAI, but training is a different timeline)
- Enterprise platforms with 10+ user roles and complex permission systems
- Native mobile apps — we build progressive web apps that work on mobile, but if you need App Store distribution, that's a different conversation
If your idea falls into one of these categories, we'll tell you on the discovery call and recommend a realistic timeline instead.
The Stack in Detail
| Layer | Technology | Why |
|---|---|---|
| Frontend | Next.js 15 (App Router) | Server Components, TypeScript, ISR, streaming |
| Backend/DB | Supabase | PostgreSQL, Auth, Storage, Realtime, Edge Functions |
| Hosting | Vercel | Edge network, CI/CD, preview deployments |
| Payments | Stripe | Subscriptions, one-time, marketplace splits |
| Resend or SendGrid | Transactional emails, onboarding sequences | |
| Analytics | PostHog or Plausible | Privacy-friendly, event tracking |
| Design | Tailwind CSS + shadcn/ui | Consistent, accessible, fast to build |
| Search | Algolia (if needed) | Fast, typo-tolerant search |
This isn't a toy stack. These are the same tools running SaaS products with thousands of paying users. We just configure them in days instead of months.
Pricing
Our 30-Day MVP Sprints start at £12,000 for a standard scope (auth, dashboard, 2-3 core features, payments). Complex scopes with real-time features, multiple integrations, or advanced data models go up to £25,000.
50% upfront, 50% on delivery. You know the number before we start.
What Happens After Launch
Day 31 isn't the end. After your sprint, you've got options:
- Self-maintain: Your code is clean, documented, and standard Next.js/Supabase — any competent developer can pick it up
- Ongoing retainer: We offer monthly development sprints for iteration based on user feedback
- Scale engagement: When you raise your round, we can expand scope and team to match your growth
The point of an MVP is to learn. We build it so you can learn fast, then decide what's next with real data instead of assumptions.
Common questions
How much does a 30-day MVP sprint cost?
Our sprints start at £12,000 for standard scope (authentication, dashboard, 2-3 core features, payments integration) and go up to £25,000 for complex scopes with real-time features or advanced integrations. It's 50% upfront, 50% on delivery. You know the exact number before we write a single line of code.
I'm not technical — can I still work with you?
Absolutely — most of our clients are non-technical founders. We handle all technical decisions and explain them in plain English. You'll review wireframes in Figma, click through preview deployments in your browser, and give feedback on things you can actually see rather than code you can't read. That's the whole point.
Do I own the code after the sprint?
Yes, 100%. You get full source code ownership with no licensing fees, no recurring platform costs from us, and no lock-in of any kind. The codebase follows standard Next.js and Supabase conventions, so any competent developer can maintain and extend it after handover.
What if my app idea is too complex for 30 days?
We'll tell you on the discovery call — no runaround. Marketplaces with complex matching, custom AI model training, or enterprise platforms with 10+ user roles typically need 45-60 days minimum. We'll give you a realistic timeline and help you figure out which features to ship first as a 30-day phase one.
Why Next.js and Supabase instead of other technologies?
Next.js gives us server-side rendering, TypeScript safety, and Vercel's edge network for fast global performance. Supabase handles the backend heavy lifting — a production PostgreSQL database, authentication, file storage, and real-time features out of the box. What would normally take weeks of custom backend work gets configured in hours.
Can you build a mobile app in 30 days?
We build responsive progressive web apps that work well on mobile browsers, including features like push notifications and offline support. If you specifically need App Store or Google Play distribution, that's a separate conversation — but honestly, most MVPs validate faster as web apps first anyway.
What happens after the 30 days?
You get 30 days of post-launch bug fix support included. After that, you can self-maintain with your own developer, engage us on a monthly retainer for iteration sprints, or scale up the engagement when you raise funding. Either way, your code is documented and fully portable — it doesn't disappear if we stop working together.
Do you work with founders in the US and UK?
Yes. We work with founders across the UK, London, and the US, with timezone-aligned standups and demo sessions built into the sprint. Whether you're in EST or GMT, you're never waiting overnight for a response or a decision.

Free consultation. No commitment. Just an honest conversation about your project.
