TL;DR: Startups spend billions on tools, consultants, and development based on assumptions, while spending virtually nothing on direct customer feedback. I analyzed the math behind this backwards economy and built satirical tools to show how absurd it really is.


The $50 Billion Irony

Here's a statistic that should make every founder uncomfortable:

U.S. startups spend approximately $50 billion annually on assumption-based decision making.

That includes:

  • $15B on development of features nobody wants
  • $12B on marketing to the wrong audiences
  • $8B on analytics tools to guess user behavior
  • $7B on consultants to validate founders' hunches
  • $5B on market research about hypothetical customers
  • $3B on pivots after building the wrong thing

Meanwhile, the same founders spend less than $50 million annually on direct customer feedback.

That's a 1,000:1 ratio of assumption spending to customer insight spending.

The Real Cost of Guessing Wrong

Let's break down what this assumption economy actually costs:

Failed Features: $15 Billion Annually

The Math:

  • 70% of new product features are never used (Source: Pendo)
  • Average feature development cost: $50,000-$200,000
  • U.S. startups develop ~500,000 features annually
  • 350,000 of those features are complete waste

Real Examples:

  • Google+ ($2.5B): Built assuming people wanted Google's social network
  • Quibi ($1.75B): Assumed people wanted premium short-form content
  • Segway ($100M): Assumed everyone would want personal transportation devices
  • New Coke ($4M): Assumed people wanted sweeter cola

The Satirical Solution: OnlyFeedback's "Premium Access" tier for $99/month gives you "access to customers who switched to competitors."

Reality check: A simple survey asking "What features do you actually use?" costs $0.

Wrong Target Markets: $12 Billion Annually

The Math:

  • 42% of startups fail due to no market need (Source: CB Insights)
  • Average startup marketing spend: $200,000 first year
  • ~300,000 U.S. startups launch annually
  • 126,000 are marketing to markets that don't want their product

Real Examples:

  • Theranos: Assumed consumers wanted at-home blood testing
  • Juicero: Assumed people would pay $400 for WiFi-connected juicing
  • Google Glass: Assumed consumers wanted face-mounted computers
  • Facebook Home: Assumed Android users wanted Facebook as OS

The Satirical Solution: AssumptionMatch.com lets you swipe on target markets like "Enterprise Decision Maker" (interested in: being hard to reach, having complex procurement processes).

Reality check: Customer interviews reveal actual market needs and willingness to pay.

Analytics Without Context: $8 Billion Annually

The Math:

  • Average startup spends $2,000-10,000/month on analytics tools
  • 80% of collected data is never acted upon
  • Analytics tools tell you WHAT happened, not WHY
  • Founders use analytics to confirm assumptions, not challenge them

The Problem:

  • "Conversion rate dropped 15%" → Assumption: Design is bad
  • "Users spend less time on feature X" → Assumption: Feature needs improvement
  • "Mobile traffic increased" → Assumption: Need mobile app

The Satirical Solution: Customer Mind Reader University's "Crystal Ball Analytics" course teaches divination-based data interpretation.

Reality check: Customer feedback explains the WHY behind your analytics.

Assumption Validation Consultants: $7 Billion Annually

The Math:

  • Average consulting project: $50,000-250,000
  • Most consulting validates existing founder assumptions
  • Consultants use industry reports, not customer interviews
  • Results sound scientific but are built on other people's assumptions

Common Consultant Deliverables:

  • Market sizing based on TAM/SAM calculations (assumptions)
  • Competitive analysis of what others assume
  • User personas based on demographic data (not actual users)
  • Product roadmaps based on "best practices" (other companies' assumptions)

The Satirical Solution: Assumption Detox Spa's "Mindful Market Research" ($599) includes "Tibetan singing bowl user research" and "market opportunity vision quest."

Reality check: Direct customer conversations cost less and provide actual insights.

The Psychology of the Assumption Economy

Why do founders prefer paying for assumption validation over free customer feedback?

1. Confirmation Bias is Expensive but Comfortable

Assumption validation confirms what founders want to believe.

  • Analytics dashboard showing growth → "We're on the right track"
  • Consultant report validating strategy → "We're strategic geniuses"
  • Competitor doing similar thing → "This validates our approach"

Customer feedback challenges assumptions.

  • "I don't understand your value proposition"
  • "This feature makes my workflow harder"
  • "Your pricing is confusing"
  • "I use your competitor because..."

The Satirical Response: Assumption Rehab Center's intake assessment asks "Do you get defensive when customers give negative feedback?" Options include "Always" and "I haven't talked to customers in over a year."

2. Paying Feels More Professional

Free customer feedback feels too easy:

  • "If it's free, it can't be valuable"
  • "Real insights require sophisticated tools"
  • "We need data scientists, not customer conversations"

Expensive assumption validation feels legitimate:

  • "We spent $100k on market research"
  • "Our analytics stack costs $5k/month"
  • "We hired top consultants"

The Satirical Response: OnlyFeedback charges $299/month for "Creepy Level Access" including "1-on-1 customer confession calls" and "custom roast my product sessions."

The irony: Real customer calls are free and infinitely more valuable.

3. Assumptions Scale, Feedback Doesn't

Founders think:

  • "I can't interview every customer"
  • "Surveys don't scale"
  • "Analytics gives me data on everyone"

The reality:

  • You need 5-10 interviews to identify patterns
  • Monthly surveys to 100 customers reveal major trends
  • Analytics without customer context leads to wrong conclusions

The Satirical Response: Customer Mind Reader University offers "Entrepreneurial Telepathy" to "develop psychic abilities to read customer minds across vast distances."

The Assumption Economy Food Chain

Here's how the $50B assumption economy perpetuates itself:

Level 1: Tool Vendors

  • Sell analytics, A/B testing, user behavior tools
  • Market based on "data-driven decision making"
  • Actually enable assumption-driven interpretation

Level 2: Consultants

  • Use Tool Vendor data to create reports
  • Apply "industry expertise" (assumptions from other clients)
  • Deliver recommendations that sound scientific

Level 3: Founders

  • Buy tools and hire consultants
  • Feel data-driven and professional
  • Make expensive decisions based on validated assumptions

Level 4: Investors

  • Fund startups with "sophisticated" approaches
  • Prefer data-heavy pitches over customer testimonials
  • Perpetuate cycle by rewarding assumption validation

Everyone profits except the customer—and ultimately, the startup.

The Simple Mathematics of Customer Feedback

Let's compare the ROI of assumption-based vs. customer-driven approaches:

Assumption-Based Feature Development

  • Analytics tools: $5,000/month × 12 = $60,000
  • Development time: 6 months × $100,000 = $600,000
  • Marketing failed feature: $50,000
  • Total cost: $710,000
  • Success rate: 30%
  • Expected ROI: -$497,000

Customer-Driven Feature Development

  • Customer interviews (20 @ 1 hour each): $0
  • Survey tools: $100/month × 12 = $1,200
  • Development time: 4 months × $100,000 = $400,000
  • Marketing validated feature: $30,000
  • Total cost: $431,200
  • Success rate: 80%
  • Expected ROI: $345,000

The difference: $842,000 per feature.

Case Study: The $1.7 Billion Assumption

Quibi raised $1.75 billion based on assumptions:

  • Assumption: People want premium short-form content
  • Assumption: Mobile-only viewing is the future
  • Assumption: Hollywood talent guarantees success
  • Assumption: Commuters need entertainment

What they never did: Ask potential customers if they wanted this.

What customers actually said (after launch):

  • "I already have TikTok and YouTube"
  • "Why can't I watch on my TV?"
  • "This content isn't worth paying for"
  • "I don't watch video during commutes"

The satirical parallel: Assumption Detox Spa's "Full Moon Assumption Release" ceremony ($899) includes "moonlight assumption burning ceremony" and "midnight market research ritual."

Quibi's $1.75B could have funded 875,000 customer interviews.

Breaking the Assumption Economy

The solution isn't complex—it's embarrassingly simple:

Replace This:

  • Monthly analytics subscriptions → Monthly customer surveys
  • Quarterly consultant reports → Quarterly customer interviews
  • Annual market research → Annual customer feedback analysis
  • Feature roadmaps based on "best practices" → Roadmaps based on customer requests

The Economics:

  • Current approach: $50,000-200,000 per major decision
  • Customer feedback approach: $500-2,000 per major decision
  • Accuracy improvement: 30% → 80% success rate
  • Speed improvement: 6-month assumptions → 2-week validation

The Tools That Made the Point

I built 5 satirical tools to show founders how their assumption-based behavior looks from the outside:

OnlyFeedback: Subscription service for customer insights ($299/month) Mind Reader University: Fake degree in assumption-making AssumptionMatch: Dating app for business assumptions
Assumption Detox Spa: Wellness retreat for assumption addiction Assumption Rehab Center: Medical facility for assumption recovery

Each tool went viral because founders recognized their own behavior in the satire.

The most common response: "This is funny but also makes me uncomfortable because it's too accurate."

The $50 Billion Opportunity

Here's the opportunity hidden in the assumption economy:

For founders: Stop paying to validate assumptions. Start paying to learn from customers.

For tool vendors: Build tools that facilitate customer feedback, not just analytics.

For consultants: Offer customer research services, not assumption validation.

For investors: Fund startups that can prove customer demand, not just market theories.

The Meta-Question

After analyzing the $50B assumption economy and building satirical tools to mock it, I have to ask myself:

Did I survey founders before writing this blog post about the importance of surveying customers?

The answer is no. I made assumptions about what founders would find interesting and compelling.

Which is either:

  1. Peak founder hypocrisy
  2. Perfect meta-commentary on how ingrained assumption-making is
  3. Both

I'm going to go with "both" and survey founders about whether they found this post useful.

Because even when you're writing about the importance of not making assumptions, it's surprisingly easy to... make assumptions.

Maybe that's the real $50 billion insight: We're all assumption addicts in recovery.

The first step is admitting we have a problem.
