Finding Ideas Worth Building
Most SaaS ideas are worthless. Not because they’re bad ideas—many are clever and interesting—but because they solve problems people don’t care enough about to pay for.
This lesson teaches you to find the other kind: problems so painful that people actively search for solutions and gladly pay for relief.
The Idea Spectrum
flowchart LR
A[Vitamin] --> B[Painkiller]
B --> C[Addiction]
A --> |"Nice to have"| A
B --> |"Must solve"| B
C --> |"Can't live without"| CVitamins: Nice to have. People might use them if free. They rarely pay. Example: “Track your daily water intake”
Painkillers: Solve real problems. People actively look for solutions and pay. Example: “Automatically reconcile your invoices with bank statements”
Addictions: So valuable that canceling feels impossible. Example: “The tool that runs your entire business workflow”
As a side hustler with limited time, focus on painkillers. They’re easier to sell than vitamins and easier to build than addictions.
Where Ideas Actually Come From
1. Your Own Frustrations
The best SaaS ideas often come from problems you personally experience.
Questions to ask yourself:
- What repetitive tasks annoy me at work?
- What do I do manually that could be automated?
- What spreadsheet do I maintain that could be a product?
- What tool do I wish existed?
Example: A freelance designer frustrated with invoice chasing built a payment reminder SaaS. She knew the problem deeply because she lived it.
2. Your Industry Knowledge
You have expertise. That expertise reveals problems invisible to outsiders.
Questions to ask:
- What do people in my industry complain about?
- What’s everyone doing inefficiently but accepting as normal?
- What tools does my industry use that everyone hates?
- What regulations or requirements create busywork?
Example: An accountant noticed everyone manually checking VAT numbers. Built a simple API that automated the verification. Boring problem, profitable solution.
3. Existing Tool Gaps
People already use tools. Those tools have limitations. Limitations are opportunities.
Questions to ask:
- What’s missing from tools you use daily?
- What integrations don’t exist but should?
- What do people complain about in tool reviews?
- What workarounds do people create?
Example: Zapier doesn’t handle complex conditional logic well. Someone built a tool specifically for multi-branch automation workflows.
4. B2B Over B2C
For side hustlers, B2B (business-to-business) beats B2C (business-to-consumer).
Why B2B:
- Businesses have budgets
- ROI is easier to demonstrate
- Higher prices ($50-500/month vs $5/month)
- More rational purchasing decisions
- Smaller customer base needed
B2C challenges:
- Price sensitivity (people hate paying $5/month)
- Emotional decisions
- Need massive scale
- Support expectations are high
Rule of thumb: Can you charge $50+/month? If not, reconsider the idea.
The Idea Validation Checklist
Before getting excited about an idea, check these boxes:
✅ Is it a painkiller?
- Does this solve a real, urgent problem?
- Are people actively searching for solutions?
- Is the pain recurring (not one-time)?
✅ Can you reach customers?
- Do you know where these people hang out?
- Can you access them without spending money?
- Are they already in communities you can join?
✅ Will they pay enough?
- Is this a $50+/month problem?
- Do businesses (not just individuals) have this problem?
- Can you demonstrate clear ROI?
✅ Can you build it?
- Is this within your technical abilities?
- Can you build an MVP in 4-8 weeks?
- Does it require infrastructure you can’t afford?
✅ Is the market right?
- Are there existing solutions (validation) but room for improvement?
- Is the market growing?
- Are customers accessible online?
The Idea Generation Exercise
Let’s generate some ideas right now.
Step 1: List Your Contexts
Write down:
- Your current job/industry
- Past jobs/industries
- Hobbies with communities
- Skills you have
Example:
- Current: Marketing manager at SaaS company
- Past: Freelance copywriter
- Hobby: Running a small e-commerce side business
- Skills: Data analysis, copywriting, basic coding
Step 2: List Frustrations in Each Context
For each context, write 3-5 frustrations or inefficiencies.
Example (Marketing manager):
- Creating reports from multiple tools takes hours
- Finding which content drives conversions is painful
- Coordinating with contractors is messy
- Tracking campaign ROI across channels is manual
Step 3: Filter Through the Checklist
Take each frustration and run it through the validation checklist.
Example analysis: “Creating reports from multiple tools takes hours”
- Painkiller? Yes—time waste is real and recurring
- Reach customers? Yes—marketing communities everywhere
- Pay enough? Maybe—depends on time savings
- Can build? Yes—APIs exist for major tools
- Market right? Existing solutions exist but are complex/expensive
This idea passes initial screening. Worth exploring further.
Step 4: Rank by Fit
Score each surviving idea on:
- Personal interest (you’ll work on this for months)
- Domain expertise (you understand the problem)
- Technical feasibility (you can actually build it)
- Market access (you can reach customers)
Pick the top 2-3 ideas to validate in the next lesson.
Idea Patterns That Work
Pattern 1: The Integration Bridge
Connect two tools that don’t talk to each other natively.
Example: Sync Notion databases with Google Sheets automatically.
Pattern 2: The Automation Layer
Automate a manual workflow in a specific industry.
Example: Auto-generate social media posts from blog content for marketers.
Pattern 3: The Reporting Dashboard
Aggregate data from multiple sources into one view.
Example: Single dashboard for all e-commerce metrics (Shopify + ads + email).
Pattern 4: The Compliance Tool
Help businesses meet regulatory requirements.
Example: GDPR consent management for small websites.
Pattern 5: The Niche CRM
Build a CRM for a specific profession with specific needs.
Example: CRM for real estate agents with property-specific features.
Pattern 6: The Workflow Optimizer
Take a common process and make it faster/easier.
Example: Proposal generation for freelance consultants.
Anti-Patterns: Ideas to Avoid
❌ Social Networks
Require massive network effects. Impossible as a side project.
❌ Marketplaces
Need both supply and demand. Chicken-and-egg problem.
❌ Hardware + Software
Hardware has long lead times, high costs, physical logistics.
❌ AI-First Products
Unless AI is your expertise, you’re competing with well-funded companies.
❌ Developer Tools (Usually)
Developers are hard customers—they’ll build it themselves or use free alternatives.
❌ “Uber for X”
If it requires physical logistics or local presence, skip it.
