Ideation: Generating Business Ideas

How to systematically generate, filter, and select business ideas worth validating.

The Mindset Shift

Most people wait for the "perfect idea" to strike like lightning. This is backwards.

The truth: Good ideas come from systematic observation, not divine inspiration.

  • Edison didn't wait for inspiration, he ran experiments
  • Great founders see problems everywhere
  • Ideas are abundant; execution is rare
  • Your first idea is rarely your best

Strategy: Generate many ideas, filter ruthlessly, validate cheaply.

Where Good Ideas Come From

1. Problems You've Experienced

The best starting point: Your own frustrations.

Examples:

  • Airbnb: Founders couldn't afford rent in SF
  • Dropbox: Founder kept forgetting his USB drive
  • Spanx: Sara Blakely wanted better undergarments
  • DoorDash: Founders noticed restaurants had no delivery

Exercise: Write 10 problems you've faced in the last month that made you think "there has to be a better way."

2. Industry Experience

Your professional expertise is valuable:

  • You understand the problems
  • You know the customers
  • You speak the language
  • You have networks

Examples:

  • ServiceTitan (plumbing software): Founder's parents owned plumbing business
  • Gusto (payroll): Founder worked in payroll industry
  • Toast (restaurant POS): Founders worked in restaurant tech

Exercise: List 5 major pain points in your industry that everyone complains about.

3. Observing Others' Problems

Watch people work. Where do they struggle?

Observation techniques:

  • Shadow someone for a day
  • Watch how people use existing tools
  • Notice workarounds and hacks
  • Listen to complaints in forums/Reddit

Example: The Knot (wedding planning) came from watching how chaotic wedding planning was.

Exercise: Spend 2 hours watching someone work in a different field. Note every frustration.

Spot the wave before it crests:

  • New technologies (AI, blockchain, VR)
  • Regulatory changes (GDPR, cannabis legalization)
  • Demographic shifts (aging population, remote work)
  • Cultural movements (sustainability, wellness)

The pattern: When platform X emerges, all the tools from platform Y need to be rebuilt for X.

Examples:

  • Mobile apps after iPhone launch
  • Cloud tools after AWS
  • AI wrappers after GPT-3/4
  • No-code tools after Webflow/Bubble

Exercise: Pick an emerging trend. What tools will people need?

5. Combining Existing Ideas

Most "new" ideas are combinations:

  • Instagram = Photo filters + Social sharing
  • Uber = GPS + Taxi dispatch + Mobile payments
  • Twitch = YouTube + Live streaming + Gaming
  • Shopify = E-commerce + Easy website builder

Exercise: Take two successful products and combine them. What would "Uber for X" or "Airbnb for Y" look like? (But be more creative than that cliché.)

Ideation Frameworks

The "I Wish" Exercise

Complete these sentences 20 times:

  • "I wish there was a way to..."
  • "I wish someone would make..."
  • "I wish it was easier to..."

Example outputs:

  • "I wish there was a way to find reliable contractors"
  • "I wish someone would make parking easier in cities"
  • "I wish it was easier to learn languages"

The Jobs-to-Be-Done Approach

People don't want products, they want to make progress in their lives.

Framework: "When I [situation], I want to [motivation], so I can [outcome]."

Examples:

  • When I'm hungry at work, I want quick healthy food, so I can stay productive
  • When I'm traveling, I want to stay connected, so I can work remotely
  • When I'm learning, I want immediate feedback, so I can improve faster

Exercise: List 10 "jobs" people are trying to do in your target market.

The Problem Mining Method

Sources of problems:

  1. Reddit complaint threads
  2. Amazon 1-star reviews
  3. Industry forums
  4. Customer support tickets (if you have access)
  5. Twitter searches for "I hate when..."

Process:

  • Spend 2 hours reading complaints
  • Categorize by theme
  • Note frequency and intensity
  • Identify patterns

Example: Search "I hate booking" on Twitter → common frustrations → potential solutions.

The Multiplication Method

Formula: [Target Customer] + [Problem Type] = Idea

Examples:

CustomerProblemIdea
DentistsSchedulingAutomated appointment system
ParentsMeal planningWeekly family meal subscriptions
FreelancersInvoicingSimple invoice software
Dog ownersWalkingDog walking marketplace
StudentsNote-takingAI-powered study assistant

Exercise: Pick 5 customer types you understand. List their top 3 problems.

Filtering Ideas: The Quick Test

You'll generate dozens of ideas. Most are bad. That's fine.

Filter #1: Personal Fit

  • [ ] Do I care about this problem?
  • [ ] Would I work on this for 5 years?
  • [ ] Do I have relevant expertise or access?
  • [ ] Am I willing to become an expert in this domain?

Filter #2: Market Basics

  • [ ] Is the market growing or stable?
  • [ ] Are there at least 10,000 potential customers?
  • [ ] Can customers afford my solution?
  • [ ] Can I reach these customers?

Filter #3: Problem Quality

  • [ ] Is this problem frequent (weekly or more)?
  • [ ] Is it painful (people actively seek solutions)?
  • [ ] Do people currently pay to solve it?
  • [ ] Are current solutions inadequate?

Filter #4: Feasibility

  • [ ] Can I build an MVP in 3 months?
  • [ ] Can I validate in 2 months?
  • [ ] Do I need less than $50,000 to start?
  • [ ] Is the path to first revenue clear?

Scoring: Each "yes" = 1 point. Need 12+ to proceed.

Instructions:

  1. List your top 5 ideas
  2. Score each on 1-10 for each criteria
  3. Multiply by weight
  4. Sum the weighted scores
  5. Pick the top 2 for validation

Validating Your Validation Approach

Before validating an idea, validate that you can validate it:

Can you reach 50 potential customers in 2 weeks?

  • No → Pick a different customer segment
  • Yes → Continue

Can you test your core assumption for under $500?

  • No → Simplify your test
  • Yes → Continue

Can you build an MVP in 12 weeks?

  • No → Reduce scope or pick different idea
  • Yes → Continue

Do you know what metrics would prove/disprove your hypothesis?

  • No → Define success criteria first
  • Yes → Continue

Common Ideation Mistakes

MistakeBetter Approach
"No one else is doing this"Usually means no market demand
"This market is huge"TAM doesn't matter if you can't reach customers
"I have a unique solution"Start with the problem, not the solution
"I'll figure it out later"Validate monetization from day one
"Building features no one asked for"Let customers guide your roadmap
"Chasing trends without expertise"Build where you have unfair advantages
"Solving small, rare problems"Focus on frequent, painful problems

The Unfair Advantage Framework

Best ideas build on your unfair advantages:

Types of unfair advantages:

  1. Insider information - You understand the customer deeply
  2. Network - You have access to customers/partners
  3. Expertise - You're 10x better at something relevant
  4. Resources - You have capital, time, or tools others don't
  5. Status - You have credibility in the space

Exercise: List your unfair advantages. Which ideas build on them?

Red Flags: Bad Ideas

Avoid these patterns:

"It's Like Uber for X"

  • Usually means no deep thinking
  • Just copying someone else's model
  • Ignoring what makes Uber actually work (network effects, high frequency)

"We'll Get Users First, Monetize Later"

  • Only works for social networks with strong network effects
  • Usually means no clear value proposition
  • Customers who won't pay won't stay either

"We Just Need 1% of a Huge Market"

  • Markets don't work this way
  • 1% of a market is still incredibly hard to get
  • Shows lack of understanding of customer acquisition

"Our Competition Is Doing It Wrong"

  • Maybe, but probably you don't understand their constraints
  • Successful companies aren't stupid
  • What do they know that you don't?

"We'll Build a Platform"

  • Platforms are incredibly hard (chicken-and-egg problem)
  • Start with a single-player use case
  • Build platform features after proving core value

Moving from Idea to Validation

Once you've selected your idea:

Step 1: Write your hypothesis "I believe [target customer] has [problem] and would [behavior] if I built [solution]."

Example: "I believe busy professionals have trouble eating healthy at lunch and would pay $15/day for delivered healthy meals at their desk."

Step 2: Identify assumptions List everything that must be true for this to work:

  • People eat lunch at their desk
  • They care about eating healthy
  • Current options are inadequate
  • They'll pay $15/day
  • We can deliver profitably at that price

Step 3: Rank by risk Which assumption, if wrong, kills the idea?

Step 4: Design tests For each critical assumption, design a cheap test.

Step 5: Set success criteria What evidence would prove/disprove each assumption?

Now you're ready to validate. Move to Chapter 2: Problem Validation.
