When Is It Worth Building Another App in a Saturated Market?
The Problem
“Don’t build another to-do app. The market is saturated.”
I heard this advice everywhere when I started my project. Product Hunt has thousands of to-do apps. The App Store is flooded. Every developer has built one. Everyone said I was wasting my time.
But I built it anyway. And it taught me something counterintuitive: saturated markets are often the best places to build.
Here’s the truth that most advice ignores:
Market Saturation Myths vs Reality
MYTH: "Saturated market = No opportunity"REALITY: "Saturated market = Validated demand + Hidden gaps"
MYTH: "Too many competitors = No room for you"REALITY: "Many competitors = Many underserved users"
MYTH: "Build something unique and new"REALITY: "Build something better for a specific group"Let me explain why conventional wisdom about saturated markets is wrong, and when building in a crowded space actually makes perfect sense.
Why Saturated Markets Attract Competitors
First, I needed to understand why markets become saturated in the first place. Saturation isn’t random—it’s a signal.
Market Saturation Lifecycle
┌──────────────────────────────────────────┐ │ │ │ HIGH DEMAND DETECTED │ │ (Early adopters find success) │ │ │ └─────────────────┬────────────────────────┘ │ ▼ ┌──────────────────────────────────────────┐ │ │ │ COMPETITORS ENTER │ │ (Everyone wants a piece) │ │ │ └─────────────────┬────────────────────────┘ │ ▼ ┌──────────────────────────────────────────┐ │ │ │ MARKET "SATURATION" │ │ (Many options, many gaps) │ │ │ └──────────────────────────────────────────┘
KEY INSIGHT: Saturation proves demand exists.A saturated market tells you three things:
- People want this solution - Real users are paying for existing products
- The problem is worth solving - Competitors wouldn’t stay if there was no money
- Opportunities exist - Every solution has unhappy users
When I analyzed the to-do app market, I found something surprising: despite thousands of apps, users were still complaining. That meant opportunities.
The Gap Discovery Framework
I developed a framework to find opportunities in saturated markets. Here’s what I learned from analyzing successful entrants in crowded spaces.
Step 1: Listen to the Complaints
The most valuable signal in a saturated market is user dissatisfaction. I spent weeks reading reviews of popular to-do apps:
Common User Complaints in Saturated Markets
┌─────────────────────┬─────────────────────────────────────┐│ Complaint Type │ What It Signals │├─────────────────────┼─────────────────────────────────────┤│ "Too complicated" │ Gap for simple, focused tools │├─────────────────────┼─────────────────────────────────────┤│ "Missing feature X" │ Underserved segment with specific ││ │ needs │├─────────────────────┼─────────────────────────────────────┤│ "Too expensive" │ Budget-conscious segment │├─────────────────────┼─────────────────────────────────────┤│ "Doesn't sync well" │ Technical execution gap │├─────────────────────┼─────────────────────────────────────┤│ "Ugly interface" │ Design-focused opportunity │└─────────────────────┴─────────────────────────────────────┘One review stood out: “I just want to type tasks and be done. No projects, no tags, no syncing, no notifications. Just a list.”
That’s when I realized: competitors were over-serving users who wanted simplicity.
Step 2: Identify the Overserved Segment
In saturated markets, most competitors optimize for power users. They add features, integrations, and complexity. But this leaves a gap:
Feature Creep Creates Opportunities
Power User Focus (Most Competitors):┌────────────────────────────────────────────┐│ ████████████████████████████████████████ ││ ││ Features: Projects, Tags, Labels, Due ││ Dates, Reminders, Recurring, Integrations, ││ Collaboration, Themes, API, Webhooks... │└────────────────────────────────────────────┘
Underserved Segment (The Gap):┌────────────────────────────────────────────┐│ ██ ││ ││ Features: Just tasks. That's it. │└────────────────────────────────────────────┘When I examined the to-do market, I found:
- 90% of apps targeted power users with complex features
- 10% of apps offered simplicity, but most were abandoned projects
- Users seeking simplicity had almost no good options
This insight came from a Reddit discussion where JoelSchmidt12 pointed out: “None of them fit what I personally want… there is a MASSIVE gap in that market that almost nobody is trying to fill.”
The gap wasn’t hidden. It was obvious in user complaints. But competitors ignored it because power users pay more.
Three Valid Reasons to Build in Saturated Markets
Through my research and experience, I identified three legitimate reasons to enter a crowded market.
Reason 1: You’ve Identified a Specific Gap
When you find an underserved segment, saturation becomes an advantage. The market is validated. Users exist. Revenue models are proven.
Gap-Based Entry Strategy
┌─────────────────────────────────────────────────────────┐│ ││ SATURATED MARKET ││ ││ ┌─────────┐ ┌─────────┐ ┌─────────┐ ││ │ Comp A │ │ Comp B │ │ Comp C │ ││ │ Complex │ │ Complex │ │ Complex │ ││ └─────────┘ └─────────┘ └─────────┘ ││ ││ ┌─────────────┐ ││ │ YOURS │ ← Gap ││ │ Simple │ ││ └─────────────┘ ││ │└─────────────────────────────────────────────────────────┘Key Question: Can you name the specific gap you’re filling?
If you can articulate exactly who is underserved and why, you have a real opportunity. If your answer is “I’ll be better,” keep digging.
Reason 2: You’re Building for Yourself First
This changed everything for me. As nam37 put it: “Build them to use them for themselves.”
When you build for yourself:
- You are your own guaranteed user
- You understand the problem deeply
- You can iterate without pressure
- Success doesn’t depend on market timing
Self-First Development Benefits
Traditional Approach:┌───────────────────────────────────────────────────┐│ Market Research → Build → Launch → PRAY users ││ come ││ ││ Risk: High (what if nobody wants it?) │└───────────────────────────────────────────────────┘
Self-First Approach:┌───────────────────────────────────────────────────┐│ Personal Need → Build → Use → Improve → Share ││ ││ Risk: Low (you already want it) │└───────────────────────────────────────────────────┘MyMonkeyCircus added another perspective: “Build it if you want to, just don’t try to sell it.” This is liberating. If you’re building for yourself, market size doesn’t matter.
Reason 3: You Can Execute Significantly Better
Sometimes the gap isn’t in features—it’s in execution. Poor UX, bad performance, terrible support, or slow development can create openings.
Execution Advantages That Matter
┌──────────────────────┬──────────────────────────────────┐│ Execution Area │ What "Better" Looks Like │├──────────────────────┼──────────────────────────────────┤│ Performance │ 10x faster load times │├──────────────────────┼──────────────────────────────────┤│ User Experience │ Intuitive without tutorials │├──────────────────────┼──────────────────────────────────┤│ Customer Support │ Human responses in hours, not ││ │ days │├──────────────────────┼──────────────────────────────────┤│ Development Speed │ Ship meaningful updates weekly │├──────────────────────┼──────────────────────────────────┤│ Pricing │ Fair, transparent, no dark ││ │ patterns │├──────────────────────┼──────────────────────────────────┤│ Platform Choice │ Native where competitors are ││ │ web-wrappers │└──────────────────────┴──────────────────────────────────┘But here’s the catch: “Better” is subjective. You need objective measures:
- Can you be 10x faster?
- Can you reduce clicks by 50%?
- Can you respond to support in half the time?
- Can you ship features 3x faster?
Vague “better” isn’t a strategy. Specific, measurable improvements are.
When You Should NOT Build in Saturated Markets
Just as important as knowing when to build is knowing when not to.
Red Flags: Don't Build If...
❌ "I'll just add more features" → Feature competition is a losing battle
❌ "I'll make it cheaper" → Race to the bottom destroys margins
❌ "Everyone needs this" → "Everyone" means no specific target
❌ "I'll figure out differentiation later" → You're building without a strategy
❌ "This market has so much money" → Revenue follows value, not market size
❌ "It'll be easy to stand out" → If it's easy, why hasn't it been done?I learned this lesson the hard way. My first attempt at a to-do app failed because I was just adding features to compete. No real differentiation, no specific user in mind, just “I’ll be better.”
A Decision Framework
I developed this framework to evaluate whether a saturated market is worth entering:
Saturated Market Decision Matrix
│ Gap Identified? │ │ YES │ NO │────────────────────┼──────────────────┼──────────────────┤ Building for Self? │ │ │ YES │ ✅ BUILD IT │ ⚠️ CONSIDER │ │ Low risk, │ Personal value │ │ high potential │ is enough │────────────────────┼──────────────────┼──────────────────┤ NO │ ✅ BUILD IT │ ❌ DON'T BUILD │ │ Clear strategy │ No advantage │ │ for execution │ = no chance │────────────────────┴──────────────────┴──────────────────┘
Second Check: Execution Advantage? │ ▼ ┌─────────────────────────┐ │ Can you be 10x better │ │ at something specific? │ └───────────┬─────────────┘ │ ┌───────────┼───────────┐ │ │ │ ▼ ▼ ▼ YES MAYBE NO │ │ │ ▼ ▼ ▼ ✅ BUILD ⚠️ RESEARCH ❌ DON'TWhat I Did Differently
Armed with this framework, I approached my to-do app differently:
Before (Failed Approach):
- Tried to compete on features
- Targeted “everyone”
- No specific differentiation
- Built what I thought people wanted
After (Successful Approach):
- Identified the “too simple” gap
- Built for my own minimalist needs first
- Differentiated by subtraction (removing features)
- Targeted users who hated complexity
The result? A small but loyal user base of people who felt ignored by every other to-do app.
The Validation Checklist
Before building in any saturated market, I now run through this checklist:
Market Entry Validation Checklist
□ Can I name the specific gap? (Not "better," but specific)□ Can I describe the underserved user in detail?□ Have I read their complaints in reviews/forums?□ Am I building for myself first, or a hypothetical user?□ Can I measure "better" objectively?□ Do I have an execution advantage I can articulate?□ Am I entering for the right reasons? (Not just market size)□ Can I start without external funding?□ Do I have a unique angle competitors will struggle to copy?
8+ Yes: Strong signal to build5-7 Yes: Proceed with caution, refine strategy<5 Yes: Rethink your approachSummary
In this post, I challenged the conventional wisdom that saturated markets should be avoided. The key insight is that market saturation validates demand—it proves users want solutions in that space.
Build in a saturated market when:
- You’ve identified a specific gap competitors ignore
- You’re building for yourself first
- You can execute significantly better in measurable ways
Don’t build when your only strategy is “more features,” “cheaper,” or “I’ll figure it out later.” Those approaches lead to failure in crowded markets.
The next time someone tells you “that market is saturated,” ask yourself: are they seeing competition, or are they missing opportunity?
