Underestimating Market Size: How Entrepreneurs and Investors Misjudge Opportunities

The Challenge of Estimating Market Size

Entrepreneurs and investors often face a common challenge: accurately estimating the potential market size for new products and services. This difficulty can lead to missed opportunities and undervaluation of promising ventures. A prime example of this phenomenon is the story of Shopify, as revealed in a memo from Bessemer Venture Partners.

The Shopify Example

In 2010, Shopify was raising $5 million at a $20 million valuation. The company was generating $5 million in revenue and had a Gross Merchandise Value (GMV) of $132 million. At the time, Bessemer Venture Partners made the following observations:

• Shopify had 10,000 customers total
• The $132 million GMV would put Shopify in the top 50 online retailers
• Bessemer's best-case scenario projected an exit value of $400 million in 4-6 years

Fast forward to today, and the reality is strikingly different:

• Shopify adds more than 10,000 paid customers every week
• The company is now worth approximately $130 billion
• Shopify's GMV is close to a trillion dollars annually

This dramatic underestimation of Shopify's potential market size and growth trajectory illustrates a broader trend in the world of entrepreneurship and investing.

The Psychology Behind Underestimation

Jeff Bezos, the founder of Amazon, offers an insightful perspective on this tendency to underestimate opportunities. He suggests that it's human nature to overestimate risk and underestimate opportunity. Bezos advises entrepreneurs to be aware of this bias and try to compensate against it.

This psychological tendency affects even experienced entrepreneurs and investors. Bezos himself once thought Amazon might become a $100 million revenue company at best when he was personally handling deliveries and listings.

Examples of Underestimated Markets

The tech industry is rife with examples of products and services whose potential was initially underestimated:

Meditation Apps

Initially seen as a niche market, meditation apps like Calm have grown into billion-dollar companies.

Snapchat

Originally perceived as a niche platform for ephemeral messaging, Snapchat has become a major social media player.

Airbnb

Often compared to niche services like Couchsurfing, Airbnb has revolutionized the travel industry. Today, one out of every $30 spent on travel in America is through Airbnb.

Uber

Initially seen as a luxury service for rich people in San Francisco, Uber has transformed urban transportation globally.

TikTok (formerly Musical.ly)

Dismissed as a platform for lip-syncing videos, TikTok has become one of the most popular social media apps worldwide.

The Importance of Market Expansion

One key factor often overlooked when estimating market size is the potential for market expansion. New products and services don't just capture a share of existing markets; they often create entirely new markets or significantly expand existing ones.

The Uber Effect

Bill Gurley, an early investor in Uber, highlighted this phenomenon in a blog post titled "How to Miss by a Mile." He pointed out that in San Francisco, Uber's market quickly grew to three times the size of the entire existing taxi market. This expansion occurred because Uber:

• Offered more convenience than traditional taxis
• Provided precise timing and wider availability
• Expanded into rural areas where taxis were scarce
• Lowered price points, enabling new use cases
• Influenced some people to forego car ownership

This market expansion effect is a crucial factor that's often overlooked in traditional market size estimates.

The AI Revolution and Market Size

The emergence of artificial intelligence (AI) presents another example of potentially vast market expansion. As highlighted in a Sequoia Capital presentation:

• The traditional software market was around $350 billion when cloud computing emerged
• The cloud computing market has already grown to $400 billion
• AI has the potential to replace both software and labor, potentially creating a market larger than both the current cloud and labor markets combined

This perspective underscores the difficulty of accurately predicting the size of markets for transformative technologies.

Lessons for Entrepreneurs and Investors

Given the tendency to underestimate market sizes and opportunities, what lessons can entrepreneurs and investors draw?

1. Be Open to Exponential Growth

Recognize that truly innovative products and services can create or expand markets in ways that are difficult to predict using traditional models.

2. Look Beyond Existing Markets

Don't limit your thinking to capturing a share of existing markets. Consider how your product or service might create entirely new use cases or customer segments.

3. Embrace Uncertainty

Accept that precise market size predictions for innovative products are often futile. Instead, focus on the potential for transformative impact.

4. Learn from User Behavior

Pay close attention to how early adopters use your product. They may reveal unexpected use cases that point to larger market opportunities.

5. Be Prepared to Pivot

Remain flexible in your approach. As you learn more about your market and customers, be ready to adjust your strategy to capture emerging opportunities.

6. Think Long-Term

Transformative products often take time to reach their full potential. Don't be discouraged by slow initial growth if you see signs of strong user engagement and expanding use cases.

The Role of Courage in Entrepreneurship

Recognizing larger market opportunities is one thing; acting on that recognition is another. This is where courage plays a crucial role in entrepreneurship and investing.

Warren Buffett, known for his conservative investing approach, famously said, "Rule number one: don't lose money." This approach works well in traditional value investing but can be limiting in the world of tech startups and venture capital.

In contrast, the tech investing world often requires a different mindset. As one entrepreneur put it, "In our business, the cynics get to be right, and the optimists get to be rich." This doesn't mean recklessly pursuing every opportunity, but rather having the courage to act decisively when you see significant potential.

Balancing Optimism and Risk Management

While courage and optimism are crucial, it's equally important to manage risk effectively. Even the most successful entrepreneurs and investors don't bet everything on a single opportunity.

Elon Musk, known for his ambitious ventures, has shown a nuanced approach to risk. While he's willing to invest heavily in ventures like SpaceX and Tesla, he's also been cautious about reputational risks, as evidenced by his stance on certain fundraising methods for AI projects.

The key is to find a balance between:

• Being open to transformative opportunities
• Managing personal and financial risk
• Maintaining long-term sustainability

Staying Informed Without Overload

In rapidly evolving fields like AI, staying informed is crucial. However, it's easy to become overwhelmed by the constant stream of new developments. Here are some strategies for staying informed without burning out:

1. Focus on Problem-Solving

Instead of trying to keep up with every new development, focus on how emerging technologies can solve specific problems you're facing.

2. Batch Your Learning

Consider dedicating specific periods (e.g., a week every quarter) for deep dives into new developments, rather than constantly trying to keep up.

3. Prioritize Hands-On Experience

Actually using new tools and technologies can often teach you more than just reading about them.

4. Cultivate a Network

Build relationships with people who are deeply involved in your areas of interest. They can help filter the noise and highlight truly significant developments.

Conclusion: Embracing the Unknown

The history of technology and entrepreneurship is filled with examples of opportunities that were initially underestimated. From Shopify to Uber, from WhatsApp to mobile gaming, visionaries who saw beyond conventional market size estimates have created enormous value.

As an entrepreneur or investor, it's crucial to cultivate the ability to see beyond current market sizes and imagine the transformative potential of new ideas. This doesn't mean abandoning caution or due diligence, but rather developing a more nuanced understanding of how markets can expand and evolve.

Remember the words of Airbnb co-founder Brian Chesky: "We didn't know the size of the market because we were inventing it. If we listened to market research, we would have just made a better couch surfing app."

In the end, the most successful entrepreneurs and investors are those who can balance optimism with rigorous analysis, courage with prudent risk management, and visionary thinking with practical execution. By doing so, they position themselves to capitalize on opportunities that others might overlook or underestimate.
