## The Short Answer

With £15K, you can build a properly designed, custom-coded MVP with 2-4 core features, user authentication, and professional deployment. The key is ruthless prioritisation — spend 70% of your budget on the core product, keep 15-20% for contingency, and don't try to build everything at once.

This allocation works:

| Category | Budget | What It Covers |
|----------|--------|---------------|
| Design | £2K-£3K | Brand, UI design, key screens |
| Core development | £8K-£10K | Auth, 2-3 core features, API, database |
| Deployment & DevOps | £500-£1K | Hosting, CI/CD, domain, SSL |
| Contingency | £2K-£3K | Post-launch fixes, iterations, surprises |

## Who This Is For

- **Pre-seed or bootstrapped founders** with £15K earmarked for their first product
- **Non-technical founders** trying to understand what their money should buy
- **Founders who've been quoted £30K+** and want to know if they can do it for less

This isn't for you if your budget is under £5K (consider no-code first) or over £30K (you have different problems to solve).

## Step 1: Define What "MVP" Actually Means for You

Before you spend a penny, write down the one thing your product does that makes it valuable. Not five things. One thing.

Every successful MVP we've built at [LiberateWeb](/solutions/startup-founders/) started with this exercise. The founder who says "it's a marketplace where people can list services, message each other, book appointments, leave reviews, and process payments" needs a £50K budget. The founder who says "it's a marketplace where service providers list their availability and customers book directly" needs £10K.

### The MVP Feature Audit

Take your feature list and sort it into three columns:

1. **Must have** — the product literally doesn't work without this
2. **Should have** — improves the experience but isn't essential for launch
3. **Nice to have** — you want it but users won't notice if it's missing

Your £15K covers everything in column 1 and probably half of column 2. Column 3 waits for post-launch funding or revenue.

**Typical must-haves:**
- User authentication (sign up, log in, password reset)
- One core workflow (the thing that delivers your value proposition)
- Basic dashboard or home screen
- Mobile-responsive design

**Typical should-haves:**
- Email notifications
- User profiles
- Search/filter functionality
- Basic analytics dashboard

**Typical nice-to-haves:**
- Social login (Google, Apple)
- In-app messaging
- Advanced admin panel
- Multi-language support

## Step 2: Choose Your Build Partner

With £15K, you have real options. Here's what each path actually looks like:

### Option A: Small MVP Agency (£5K-£15K)

This is the sweet spot for most non-technical founders. A small agency handles everything — design, development, deployment — and you get a finished product.

At LiberateWeb, our tiers work like this:
- **Founder (£5K):** Auth + one core feature + clean design, 2-4 weeks
- **Growth (£10K-£15K):** 3-4 features, more complex logic, polished UX, 4-6 weeks

With £15K, you're comfortably in Growth territory. That buys you a properly designed, multi-feature product with room for contingency.

### Option B: Senior Freelancer (£8K-£12K) + Designer (£2K-£3K)

If you're comfortable managing two contractors, this can work well. Hire a senior full-stack developer (£60-£80/hour, ~120-150 hours) and a UI designer separately.

**Risk:** You're the project manager. You coordinate timelines, resolve conflicts, and handle integration issues. Fine if you're experienced at this. Stressful if you're not.

### Option C: Technical Co-Founder + Budget for Design

If you have a technical co-founder willing to build, spend £2K-£3K on professional UI/UX design and let them code. The remaining £12K becomes runway, marketing budget, or contingency.

This is the most capital-efficient path but requires real technical capability, not "I did a coding bootcamp once."

## Step 3: Choose a Stack That Respects Your Budget

Your tech stack directly impacts what you can build for £15K. Some stacks are inherently faster (and therefore cheaper) to build with.

### Our Recommended Stack for £15K MVPs

- **Next.js** — React framework with server-side rendering, API routes, fast builds
- **Tailwind CSS** — utility-first styling, no custom CSS to maintain
- **Supabase** — database, auth, storage, real-time — replaces 3-4 separate services
- **Vercel** — deployment, hosting, CI/CD — free tier covers most MVPs

This stack is fast to develop with, cheap to host (under £20/month for most MVPs), and scales when you need it to. It's what we use at LiberateWeb because it lets us deliver more product per pound.

### Stacks to Avoid on a Budget

- **Ruby on Rails** — great framework, but Rails developers are expensive in the UK
- **Microservices** — you don't need Kubernetes for 100 users
- **Custom auth** — use Supabase Auth or Auth0, don't build login from scratch
- **Native mobile apps** — web-first, always, until you've proven demand

## Step 4: Allocate the Budget

A realistic breakdown for a £15K MVP with 3 core features:

### Design Phase (£2K-£3K, Week 1-2)

- Brand identity (logo, colours, typography): £500-£1K
- UI design for 5-8 key screens: £1K-£1.5K
- Mobile responsive layouts: included
- Design system/component library: £500

Don't skip design. A well-designed MVP with two features outperforms an ugly MVP with five features — both with users and investors.

### Development Phase (£8K-£10K, Week 2-6)

- Project setup, auth, database schema: £1K-£1.5K
- Core feature 1 (primary value prop): £2K-£3K
- Core feature 2: £2K-£2.5K
- Core feature 3: £1.5K-£2K
- Testing, bug fixes, polish: £1K-£1.5K

### Deployment Phase (£500-£1K, Week 6-7)

- Domain registration and DNS: £20-£50
- Vercel deployment setup: £0 (free tier)
- Supabase production setup: £25/month
- Email service (Resend, Postmark): £0-£20/month
- Basic monitoring (Sentry free tier): £0

### Contingency (£2K-£3K)

Keep this untouched until after launch. You will need it. Every MVP has post-launch surprises — a flow that doesn't work on Safari, a database query that's slow with real data, user feedback that requires a quick pivot.

## Step 5: Timelines That Actually Work

| Phase | Duration | Key Deliverables |
|-------|----------|-----------------|
| Scoping & design | 1-2 weeks | Finalised feature list, UI designs, database schema |
| Sprint 1 | 2 weeks | Auth, core feature 1, basic layout |
| Sprint 2 | 2 weeks | Features 2-3, integrations, responsive design |
| Polish & launch | 1 week | Testing, bug fixes, deployment, analytics |
| **Total** | **5-7 weeks** | |

## Common Mistakes That Waste Budget

**1. Building an admin panel too early.** You don't need a custom admin dashboard for 50 users. Use Supabase's built-in dashboard or a simple tool like Retool.

**2. Over-engineering authentication.** Social login, MFA, role-based access — these are nice, but email/password with Supabase Auth takes an hour. Start there.

**3. Custom email templates.** Use a transactional email service with their default templates. Pretty emails can wait.

**4. Premature optimisation.** Don't spend £2K on caching, CDN configuration, and load balancing. Your MVP won't have enough traffic to need it.

**5. Scope creep.** The most expensive word in MVP development is "also." Every "can we also add..." costs £500-£2K and pushes your launch back a week.

## What £15K Won't Buy You

Be realistic about limitations:

- **A complete platform** — you're building version 0.1, not version 1.0
- **Native mobile apps** — web only, responsive design for mobile
- **Complex integrations** — one or two third-party APIs, not ten
- **A marketing site AND a product** — focus on the product, use a simple landing page
- **Ongoing development** — this budget covers the build, not 6 months of iteration

## Making the Most of £15K

£15K is a solid MVP budget. It sits in the sweet spot — enough to build something real, not so much that you're tempted to over-build. The founders who get the most from this budget are the ones who stay focused: one core value proposition, 2-3 features, clean design, fast launch.

Spend 70% on the build, keep 20% for contingency, and launch something you can put in front of real users within 6 weeks. Everything else is iteration.

## Frequently asked questions

### Is £15K enough for an MVP?

Yes — £15K is a solid MVP budget. It's enough for a well-designed, custom-coded product with 2-4 core features, authentication, and proper deployment. You won't build a feature-complete platform, but you'll build enough to validate with real users and impress investors.

### Should I spend my entire budget on the MVP build?

No. Keep 15-20% (£2K-£3K) as contingency for post-launch fixes, user feedback iterations, and unexpected costs. Spending every penny on the build and having nothing left for iteration is a common startup mistake.

### Can I build an MVP for less than £15K?

Absolutely. A focused MVP with one core feature can be built for £5K with the right agency. LiberateWeb's Founder tier starts at £5K. The extra budget lets you add more features, more polish, or save some for iteration.

### What's the biggest budget mistake founders make?

Building too many features. A £15K budget spread across 8 features gives you 8 half-finished things. The same budget focused on 2-3 features gives you something polished, tested, and investor-ready.

### How long does a £15K MVP take to build?

With a focused agency, 4-8 weeks. With a freelancer, 6-12 weeks. The timeline depends more on scope discipline than budget — the fastest builds are the most focused ones.
