The Uncomfortable Truth About MVP Failure Rates

Bottom line: 87% of MVPs fail to achieve their validation goals. But it's not because the ideas are bad - it's because of seven preventable mistakes made during development. We'll show you each mistake, why it kills MVPs, and exactly how to avoid it.

Why This Matters

You're about to invest £12,500-£50,000 and 2-8 weeks building your MVP. If it fails, you've lost time and money you can't get back.

But here's the thing: Most MVP failures aren't about the product idea. They're about the execution.

Common excuses founders make:

  • "The market wasn't ready"
  • "We didn't have enough funding"
  • "Our timing was off"
  • "Users didn't understand the value"

The real reasons:

  • Built the wrong features
  • Took too long to launch
  • Never actually tested with real users
  • Over-engineered the solution
  • Ignored early warning signs
  • Built for imaginary users
  • Spent money on the wrong things

Every one of these is preventable. Let's fix them.


The 7 Deadly MVP Mistakes

Mistake #1: Building Features Nobody Asked For

What it looks like:

  • "Users will definitely want dark mode"
  • "We should add social login options for 5 different platforms"
  • "Let's include an admin dashboard just in case"
  • "Advanced reporting would be nice"
  • Building based on what competitors have, not what users need

Why it kills MVPs:

  • Each unnecessary feature adds 3-10 days of development
  • More features = more bugs = more support overhead
  • Complex products confuse early users
  • You spend time on features instead of validation
  • Launch date keeps slipping

Real example of this mistake:A booking platform spent 6 weeks building:

  • Advanced calendar sync with 5 different providers
  • Automated reminders via email, SMS, and push
  • Multi-currency support
  • Team collaboration features
  • Detailed analytics dashboard

Result: Launched 12 weeks late. First user said: "I just want to book appointments easily. This is overwhelming."

How to avoid it:Use the "pain test" for every feature:

  1. What specific pain does this solve?
  2. Can we prove users have this pain?
  3. Would they pay for the solution?
  4. Is it essential for proving the core concept?

If you can't answer all four, cut it.

Our sprint process prevents this:

  • Pre-flight call focuses on core user pain
  • PRD ruthlessly prioritises P0 (must-have) vs P1/P2 (nice-to-have)
  • Only P0 features make it into Week 1
  • Everything else goes into Phase 2 backlog
  • Fixed scope means no feature creep during sprint

Week 1 sprint delivers: Core workflow that solves the main problem. Nothing more.


Mistake #2: Taking Too Long to Launch

What it looks like:

  • "We need to polish this more before showing users"
  • "Let's add just one more feature before launch"
  • "We should wait until the design is perfect"
  • "Let's do another round of revisions"
  • Month 3: Still not launched, still "almost ready"

Why it kills MVPs:

  • Market conditions change whilst you're building
  • Competitors launch whilst you're polishing
  • You run out of money before validation
  • You lose momentum and motivation
  • Early user feedback comes too late to matter

The data is brutal:

  • MVPs launched in under 8 weeks: 23% achieve validation goals
  • MVPs launched after 16+ weeks: 7% achieve validation goals

Real example:SaaS company spent 9 months building their MVP:

  • Months 1-2: Requirements and design
  • Months 3-6: Development
  • Months 7-8: Testing and polish
  • Month 9: "One more feature" before launch

By month 9:

  • Two competitors had launched
  • Initial target market had shifted to remote work
  • Funding running low
  • Team exhausted

Result: Launched to crickets. Product was well-built but no longer relevant.

How to avoid it:Set a hard launch deadline:

For simple products: 2-3 weeks maximumFor complex products: 6-8 weeks maximum

If you can't launch in that timeframe, you're building too much.

Our sprint process prevents this:

  • Pre-sprint PRD locks scope before Day 1
  • Week 1 sprint delivers working MVP in 5 days
  • No revision rounds - nightly videos keep progress on track
  • Fixed deadline: Day 5 is launch day, no exceptions
  • Optional Week 2 for polish only if Week 1 validates core assumptions

Timeline: 1-2 weeks from kickoff to working product, not 3-6 months.


Mistake #3: Never Actually Testing with Real Users

What it looks like:

  • Building in isolation for months
  • "We'll test it once it's finished"
  • Testing with friends and family (who lie to you)
  • Assuming you know what users want
  • Launching publicly without any beta testing

Why it kills MVPs:

  • Discover fundamental problems after spending all your money
  • Can't pivot because you're too invested
  • Wrong assumptions baked into the product
  • No user feedback to guide iteration
  • Don't know if anyone will actually pay

Shocking statistic: 58% of MVPs launch without any pre-launch user testing.

Real example:Fitness app spent £40,000 building:

  • Complex workout tracking
  • AI-powered recommendations
  • Social features
  • Nutrition planning
  • Progress photos with filters

Launched publicly without beta testing.

What users actually wanted: Simple way to log workouts and see progress over time. Everything else got in the way.

Result: 3% user retention after first week. £40K wasted.

How to avoid it:Test at multiple stages:

Week 1 (end of sprint):

  • Get working MVP on TestFlight or staging environment
  • Share with 10-20 target users
  • Watch them use it (don't guide them)
  • Record their reactions and frustrations

Week 2:

  • Fix obvious issues
  • Test with 20-50 more users
  • Gather quantitative data: completion rates, time to value, etc.

Week 3-4:

  • Decide: pivot, persevere, or kill based on real data
  • If persevering, plan Phase 2 features based on user feedback

Don't launch publicly until 50+ people have used it.

Our process includes testing:

  • Day 5 deliverable: Working product ready for beta users
  • Can share immediately with TestFlight, staging URLs, or private access
  • Week 1 delivers testable MVP, not beautiful designs
  • Optional Week 2 for iteration based on user feedback

Result: You're testing by Week 1, not Month 3.


Mistake #4: Over-Engineering the Solution

What it looks like:

  • "We should build this to scale to 1 million users from day one"
  • Building microservices architecture for 100 users
  • Custom authentication system instead of using Auth0/Clerk
  • Custom payment processing instead of Stripe
  • "Future-proofing" for problems you don't have

Why it kills MVPs:

  • 3-8 extra weeks of development time
  • Higher costs (£20,000-£50,000 wasted)
  • More complex = more bugs
  • Harder to pivot because architecture is rigid
  • Solving tomorrow's problems instead of today's

The paradox: Products built to "scale from day one" often never get their first users.

Real example:B2B SaaS company spent £80,000 and 16 weeks building:

  • Microservices architecture (8 separate services)
  • Custom authentication with SSO, SAML, OAuth
  • Multi-region database replication
  • Advanced caching layer
  • Custom API rate limiting
  • Extensive automated testing suite

Launched to... 12 beta users.

What they needed: Simple monolithic Next.js app with Supabase. Would have cost £12,500 and taken 1 week.

Result: Spent 12x more than necessary. Never got traction because they ran out of money before iterating.

How to avoid it:Build for your first 100-1,000 users, not your first million.

Use this decision framework:

Don't build custom:

  • Authentication → Use Clerk, Supabase Auth, or Auth0
  • Payments → Use Stripe Checkout
  • Email → Use Resend or SendGrid
  • File storage → Use Supabase Storage or S3
  • Database → PostgreSQL is fine (via Supabase)
  • Hosting → Vercel, Railway, or Render

Build custom only if:

  • Managed service doesn't exist for your use case
  • Your unique value proposition requires it
  • Compliance regulations mandate it

Architecture decisions:

  • Monolithic > Microservices (for MVP)
  • Server-side rendering > Complex frontend state management
  • Relational database > NoSQL (unless specific need)
  • Manual testing > Extensive automated testing

Can always refactor later after validation succeeds.

Our tech stack prevents over-engineering:

  • Next.js for frontend (proven, fast)
  • Supabase for backend (auth, database, storage in one)
  • React Native for mobile (one codebase for iOS/Android)
  • Vercel for hosting (zero config)
  • Stripe for payments (don't build payment processing)

Result: Production-ready in 1-2 weeks, not 3-6 months.


Mistake #5: Ignoring Early Warning Signs

What it looks like:

  • Beta users don't use the product daily (or at all)
  • Low completion rates for core workflows
  • Users asking for completely different features
  • No one wants to pay the proposed price
  • High churn in first week
  • Ignoring these signals because "they just don't understand it yet"

Why it kills MVPs:

  • Confirmation bias: only seeing what you want to see
  • Sunk cost fallacy: already invested so much
  • Keep building when you should pivot
  • Miss the opportunity to fix fundamental issues early
  • Run out of money before finding product-market fit

Critical metrics that predict failure:

Week 1 red flags:

  • Less than 30% of beta users complete core workflow
  • Users ask "what is this for?" or "how do I...?" constantly
  • Average session time under 2 minutes for productivity tools
  • Users don't come back next day/week

Week 2-4 red flags:

  • Retention drops below 20% week-over-week
  • Users say "interesting" but won't pay
  • Feature requests are completely different from your vision
  • Support questions show users don't understand value proposition

Real example:Productivity app launched with 100 beta users:

  • Week 1: 12% completed onboarding, 4% returned next day
  • Week 2: Founder added more features to "help users understand"
  • Week 3: Retention dropped to 2%
  • Week 4: Still building new features instead of investigating core problem

The actual issue: Value proposition was unclear. Users didn't know what problem it solved.

Result: Spent 8 more weeks building features. Never fixed core problem. Shut down at Month 4.

How to avoid it:Set success metrics before launch:

Minimum viable metrics for Week 1:

  • 60%+ of users complete core workflow
  • 40%+ return within 48 hours
  • Average session time shows engagement (10+ minutes for complex tools, 2+ minutes for simple tools)
  • Users can articulate what problem you solve

If you don't hit these, stop building. Start investigating.

Questions to ask failing beta users:

  1. What were you hoping to accomplish?
  2. What stopped you?
  3. If this didn't exist, what would you use instead?
  4. Would you pay for this? How much?

Honest answers tell you whether to pivot or persevere.

Our process includes metric tracking:

  • Analytics package (£1,500) includes PostHog setup
  • Track core workflows, completion rates, session times
  • Weekly analytics report template
  • We help interpret early data to spot warning signs

Result: You know if it's working by Week 2, not Month 6.


Mistake #6: Building for Imaginary Users

What it looks like:

  • "Our target market is everyone who..."
  • Creating personas based on assumptions, not interviews
  • "Ideal customer is 25-45, likes tech, wants to be productive"
  • Never talking to actual potential users before building
  • Building features you personally want

Why it kills MVPs:

  • Real users have different pain points than you imagine
  • Build for made-up problems, not real ones
  • Marketing messages don't resonate
  • Product solves nothing important
  • Can't find actual customers because you optimised for imaginary ones

The founder trap: You are not your user (usually).

Real example:Founders (all developers) built project management tool for "small teams":

  • Assumed teams wanted Jira-like complexity
  • Built detailed sprint planning, story points, burndown charts
  • Added Git integration, deploy tracking, code review workflows

Launched to actual small teams (design agencies, consultants, event planners).

Actual need: Simple todo list with client access. None of the dev-focused features mattered.

Result: Crickets. Built for themselves, not actual target market.

How to avoid it:Talk to 20-30 potential users before building anything.

Pre-sprint user research:

  1. Find 20-30 people who have the problem
  2. 30-minute interviews each
  3. Ask about current solutions and pain points
  4. Ask what they'd pay for a better solution
  5. Show simple mockups and gauge reaction

Don't ask: "Would you use this?" (everyone says yes)Do ask: "What do you use now? What frustrates you about it? Walk me through your process."

Listen for phrases like:

  • "I hate when..."
  • "I wish I could..."
  • "Currently I have to..."
  • "The biggest pain is..."

These reveal real problems worth solving.

Our pre-flight call prevents this:

  • 2-3 hour session with all stakeholders
  • We ask: Have you talked to potential users?
  • We review any user research or validation
  • We challenge assumptions about user needs
  • We recommend user interviews if you haven't done them

If you haven't talked to users, we recommend doing so before booking sprint.


Mistake #7: Spending Money on the Wrong Things

What it looks like:

  • £5,000 on branding before validating product
  • £10,000 on marketing website for unproven product
  • £15,000 on custom illustrations
  • £8,000 on professional photography
  • £3,000 on PR agency
  • Building payment processing before anyone wants to pay

Why it kills MVPs:

  • Money spent on polish instead of validation
  • Run out of budget before learning if product works
  • Sunk cost makes pivoting harder
  • Looks professional but doesn't solve real problems
  • Confusing "looking like a real company" with "being valuable to users"

Real example breakdown:

Company spent £45,000 before launch:

  • MVP development: £25,000 ✓ (necessary)
  • Branding package: £8,000 ✗ (too early)
  • Marketing website: £10,000 ✗ (too early)
  • Professional photography: £2,000 ✗ (unnecessary)

Result: Beautiful product nobody wanted. Ran out of money after 4 months.

What they should have done:

Phase 1 - Validation (£12,500):

  • Week 1 MVP sprint → Basic functional product
  • Test with 50 users
  • Validate people will pay

Phase 2 - Launch (if validation succeeds) (£10,000):

  • Branding (if needed)
  • Basic marketing website with legal pages
  • App store submission (if mobile)

Total saved until validation: £32,500

How to avoid it:Spend money in phases based on validation gates.

Pre-validation (before you know it works):✓ MVP development: £12,500-£25,000✓ Basic hosting/tools: £100-£500/month✗ Branding: Wait✗ Marketing website: Wait (unless required for app stores)✗ Content creation: Wait✗ PR/marketing: Wait

Post-validation (after 50+ users say they'll pay):✓ Branding package: £5,000✓ Marketing website: £5,000✓ App Store assets: £3,000✓ Content/marketing: £3,000-£10,000

Our pricing structure supports this:

Start minimal:

  • Week 1 MVP sprint: £12,500
  • Test with users
  • Validate or pivot

Add polish only after validation:

  • Branding Package: £5,000
  • Marketing Website: £5,000 (required for app stores)
  • App Store Assets: £3,000

Or bundle for savings:

  • Go-To-Market Package: £16,500 (save £3,200)

This approach means: You only spend on polish if the MVP validates.

The MVP Validation Framework That Actually Works

Here's the step-by-step process that gives your MVP a fighting chance:

Phase 0: Pre-Development Validation (1-2 Weeks)

Before spending any money on development:

  1. Talk to 20-30 potential users
    • 30-minute interviews
    • Understand current solutions and pain points
    • Ask about willingness to pay
  2. Create simple landing page
    • Describe the solution
    • Include "Join waitlist" button
    • Run small ads (£200-£500)
    • Target: 100+ email signups
  3. If you get 100+ signups → Build itIf you don't → Rethink the idea

Success criteria: Validated that problem exists and people want solution.


Phase 1: Build MVP (1-2 Weeks)

30-minute discovery call:

  • Assess feasibility
  • Discuss validation plan
  • Estimate timeline and cost

Pre-flight call (2-3 hours):

  • Deep dive on requirements
  • All stakeholders present
  • Challenge assumptions
  • Define success metrics

PRD and sign-off:

  • Complete requirements document
  • Clear scope (only P0 features)
  • Success metrics defined
  • Client approves before Day 1

Week 1 sprint (5 days):

  • Days 1-4: Build core functionality
  • Day 5: Test, deploy, handover
  • Nightly show-and-tell videos
  • Working MVP delivered

Cost: £12,500

Success criteria: Working product you can test with real users.


Phase 2: Beta Testing (1-2 Weeks)

Week 1 (50 users):

  • Launch to 50 beta users from waitlist
  • Watch first session recordings
  • Track completion rates
  • Survey after first use

Red flags:

  • Less than 60% complete core workflow
  • Less than 40% return within 48 hours
  • Users confused about value proposition

Green flags:

  • 60%+ complete core workflow
  • 40%+ return within 48 hours
  • Users can articulate problem it solves
  • Users asking about pricing

Week 2 (decision point):

  • If metrics hit green flags → Move to Phase 3
  • If metrics show red flags → Investigate and iterate or pivot

Success criteria: Evidence users find value.


Phase 3: Paid Validation (1-2 Weeks)

Don't just ask if they'll pay. Make them pay.

Week 1:

  • Add payment processing (if not in MVP)
  • Email beta users: "We're opening paid access. £X/month or £Y/year."
  • Target: 10%+ conversion from free to paid

Week 2:

  • Monitor payment conversion
  • Exit interviews with users who don't pay
  • Identify pricing objections

Success criteria:

  • 10%+ of beta users pay
  • Clear understanding of pricing model
  • Path to profitability visible

If less than 5% convert → Major problem with value proposition or pricing


Phase 4: Scale Preparation (2-4 Weeks)

Only if Phase 3 validates willingness to pay.

Now invest in polish:

Week 1-2:

  • Add polish from user feedback
  • Fix onboarding friction
  • Improve core workflows
  • Optional: Branding Package (£5,000)

Week 3-4:

  • Marketing Website (£5,000) - if launching on app stores
  • App Store Assets (£3,000) - if mobile
  • Content creation (£3,000)
  • Social Media Setup (£1,200)

Or use Go-To-Market Package (£16,500) for savings.

Success criteria: Ready for public launch and user acquisition.


Phase 5: Public Launch

Soft launch approach:

  • Start with Product Hunt
  • Email waitlist
  • Share in relevant communities
  • Monitor metrics closely

Key metrics:

  • Signup → Activation rate
  • Activation → Paid conversion rate
  • Customer Acquisition Cost (CAC)
  • Lifetime Value (LTV)

Target for sustainability: LTV > 3x CAC

Success criteria: Profitable unit economics visible.


Real Example: SalesLite CRM

Let's see how this framework worked in practice.

Phase 0: Pre-Development (2 weeks)

User research:

  • Interviewed 25 UK tradespeople
  • Discovered they hate desktop CRMs (too complex, always on site)
  • Use WhatsApp and paper notes currently
  • Wanted mobile-first, voice-to-text for notes
  • Willing to pay £20-30/month

Landing page validation:

  • Simple page: "Mobile CRM for tradespeople"
  • £300 in Facebook ads
  • 180 email signups in 10 days

Decision: Build it.

Phase 1: Build MVP (2 weeks)

Pre-flight call:

  • Defined core workflow: Record voice note → Auto-generate customer profile and quote → Manage pipeline
  • Decided on React Native for mobile-first
  • Chose OpenAI Whisper for voice transcription

Week 1 sprint:

  • Core CRM functionality
  • Customer database
  • Pipeline management
  • Voice recording

Week 2:

  • AI voice transcription
  • Quote generation
  • Polish and testing

Cost: £25,000 (2-week sprint)

Phase 2: Beta Testing (2 weeks)

Week 1:

  • 50 tradespeople from waitlist
  • Onboarded via TestFlight

Results:

  • 72% completed first customer entry
  • 58% returned next day to add second customer
  • 41% used it for 7+ days straight

Feedback:

  • "Finally something I'll actually use"
  • "Voice notes are game changer"
  • "PDF quotes save me hours"

Week 2:

  • Fixed minor bugs
  • Improved quote templates
  • Added 50 more beta users

Phase 3: Paid Validation (1 week)

Pricing test:

  • Offered paid access: £25/month or £250/year
  • Emailed 100 active beta users

Results:

  • 18 converted to paid (18% conversion)
  • 12 more on annual plan (12%)
  • Total: 30% willing to pay

This validated:

  • Strong willingness to pay
  • Pricing was acceptable
  • Value proposition clear

Phase 4: Scale Preparation (3 weeks)

Week 1-2:

  • Improved onboarding based on feedback
  • Added customer requested features
  • Optimised performance

Week 3:

  • Marketing Website (£5,000) with required legal pages
  • App Store Assets (£3,000) for submission
  • Submitted to Apple App Store and Google Play

Total additional investment: £8,000

Phase 5: Public Launch

Soft launch:

  • Product Hunt (featured, #3 product of day)
  • Email to 500+ waitlist
  • Posted in tradesperson Facebook groups

Month 1 results:

  • 400 signups
  • 85 paid conversions (21% conversion rate)
  • £2,125 MRR
  • Clear path to profitability

Success factors:

  1. Validated with real users before building
  2. Built fast (2 weeks)
  3. Tested with 100+ beta users
  4. Confirmed willingness to pay before scaling
  5. Only invested in polish after validation

Total investment to validation: £25,000Time to paid customers: 6 weeks

Compare to typical failed MVP:Investment: £60,000-£120,000Time to realising it doesn't work: 4-6 months


How Our Sprint Process Prevents These Mistakes

Pre-Sprint Protection

Free discovery call (30 minutes):

  • Have you talked to potential users?
  • What validation have you done?
  • Is this idea ready to build?
  • Honest assessment of feasibility

We'll tell you if you're not ready to build yet.

Pre-flight call (2-3 hours):

  • Challenge assumptions about user needs
  • Force prioritisation (P0 vs P1 vs P2)
  • Define what success looks like
  • Ensure all stakeholders aligned

PRD creation:

  • Clear scope locked before Day 1
  • Only essential features included
  • Success metrics defined
  • Client signs off

During Sprint Protection

Fixed scope:

  • No feature additions during sprint
  • PRD is locked on Day 0
  • New ideas go into Phase 2 backlog

Nightly videos:

  • See progress every day
  • Catch issues early
  • No surprises on Day 5

Stand-ups as needed:

  • Discuss blockers immediately
  • Make trade-off decisions together
  • Keep sprint on track

Modern tech stack:

  • No over-engineering
  • Managed services where possible
  • Battle-tested tools only

Result: Working MVP in 5 days, £12,500

Post-Sprint Protection

Day 5 deliverable:

  • Production-ready product
  • Ready for beta testing immediately
  • Can share via TestFlight, staging URL, or private access

Analytics included:

  • Optional Analytics Package (£1,500)
  • Track core metrics from Day 1
  • Spot warning signs early

Flexible iteration:

  • On-demand support: £200/hour
  • Monthly retainers: £1,600-£5,600/month
  • Fix issues and iterate based on user feedback

Checklist: Will Your MVP Succeed or Fail?

Go through this honestly:

Pre-Development:

  • Talked to 20+ potential users about their problems
  • Can articulate specific pain you're solving
  • Validated people will pay (landing page, interviews, etc.)
  • Know your target user intimately (not imaginary persona)

During Development:

  • Building only essential features (P0 only)
  • Launch timeline under 8 weeks
  • Using managed services instead of custom building
  • Not trying to scale to 1M users from day one
  • Fixed scope (no feature additions mid-sprint)

Post-Development:

  • Testing with 50+ real users before public launch
  • Tracking completion rates and retention metrics
  • Willing to pivot if metrics show problems
  • Validating payment before scaling
  • Spending on polish only after validation

If you checked fewer than 12 boxes, your MVP is at high risk.


The Validation-First Approach

Traditional approach (high failure rate):

  1. Have idea
  2. Spend 3-6 months building
  3. Launch publicly
  4. Discover if it works
  5. Often fails

Validation-first approach (higher success rate):

  1. Have idea
  2. Talk to 20-30 potential users
  3. Create landing page, get signups
  4. Build minimal version in 1-2 weeks
  5. Test with 50-100 beta users
  6. Validate willingness to pay
  7. Scale only if validated

Cost difference:

  • Traditional: £60,000-£120,000 before knowing if it works
  • Validation-first: £12,500-£25,000 before knowing if it works

Time difference:

  • Traditional: 4-6 months to validation
  • Validation-first: 4-6 weeks to validation

Common Questions

"But what if someone copies my idea whilst I'm testing?"

They won't. Ideas are worthless. Execution is everything. And if someone does copy you, you'll have 6 weeks of user feedback and iteration they don't have.

"Don't I need perfect designs before launching?"

No. You need working functionality. Design polish comes after validation. Most successful products started ugly.

"What if users don't understand the value in Week 1?"

That's the point of Week 1 testing. If they don't get it immediately, either:

  • Value proposition is unclear (fix messaging)
  • Onboarding is confusing (fix onboarding)
  • You're solving wrong problem (pivot)

Better to learn this in Week 2, not Month 6.

"Can't we just launch publicly and see what happens?"

You can, but 87% failure rate suggests this doesn't work. Beta testing first means you fix obvious problems before burning your launch opportunity.

"How do I know if I should pivot or persevere?"

Look at Week 2 metrics:

  • Less than 40% retention → Major problem, investigate
  • 40-60% retention → Some issues, iterate
  • 60%+ retention → Green light, persevere

And ask beta users: "Would you pay for this? How much?"

If less than 10% say yes → Pivot or killIf 10-30% say yes → Iterate and test pricingIf 30%+ say yes → You're onto something

"What if my product is too complex for 1-week sprint?"

Then build it in phases:

  • Week 1: Absolute minimum viable (core workflow only)
  • Test with users
  • Week 2: Add essential features based on feedback
  • Test again
  • Week 3-4: Polish and scale features

Never spend more than 2 weeks before user testing.

Bottom Line

Why most MVPs fail:

  1. Building features nobody asked for
  2. Taking too long to launch
  3. Never testing with real users
  4. Over-engineering the solution
  5. Ignoring early warning signs
  6. Building for imaginary users
  7. Spending money on the wrong things

How to avoid failure:

  • Validate before building (20+ user interviews)
  • Build minimum version fast (1-2 weeks)
  • Test with 50+ beta users immediately
  • Use simple tech stack and managed services
  • Track metrics and act on warning signs
  • Build for real users with real problems
  • Spend on polish only after validation

Our sprint process:

  • Pre-sprint: Discovery + pre-flight + PRD
  • Week 1: Core MVP in 5 days (£12,500)
  • Week 2: Test with users, iterate based on feedback
  • Phase 2: Scale only if validated

Timeline: 2-4 weeks to validation, not 4-6 monthsCost: £12,500-£25,000 to validation, not £60,000-£120,000

The difference between 87% failure rate and success? Building fast, testing early, and listening to users.
