Our highly personalized three-month program offers $100K in funding, expert mentorship, and a powerful network to help you achieve your business goals.
In the world of startup fundraising, one of the most influential dynamics is the herd effect. This phenomenon occurs when investors’ opinions about your startup are heavily influenced by the perceived interest of other investors. When one investor commits, it often triggers a domino effect, with others rushing to join in. This momentum can accelerate fundraising and elevate your startup’s profile, but it also introduces unique challenges and risks.
For inexperienced founders, the herd effect can be both exhilarating and perplexing. Stories of stampedes to invest in startups often create the misconception that these frenzies are the ultimate goal of fundraising. However, such events are not always indicative of a strong company. Many startups that cause investment stampedes ultimately fail, while others that secure modest investor interest go on to achieve remarkable success.
The key is understanding the forces that drive the herd effect, avoiding common mistakes, and leveraging momentum to your advantage. This guide explains these forces and offers strategies for navigating the complex dynamics of investor behavior.
Why Investors Follow the Herd
Raising Money Decreases Risk
• Every dollar raised reduces a startup’s risk of failure, making it a safer bet for subsequent investors.
• After your startup raises its first significant check, the company’s value literally increases because it now has more capital to fund operations and growth.
• Practical Tip: This logic justifies raising your valuation for later investors. Early investors took on more risk and deserve higher returns. However, tread carefully—some investors resist paying a premium and may walk away if they perceive an imbalance.
Confidence Breeds Confidence
• Success in fundraising often boosts founders’ confidence, and confidence is contagious. Investors frequently base their opinion of a startup on their perception of the founders’ conviction and capability.
• When fundraising is going well, your increased confidence becomes palpable in meetings and pitches. Investors, particularly those with strong people-reading skills, quickly pick up on this energy and are more likely to commit.
Judgment by Proxy
• Evaluating startups is challenging, even for experienced investors. Many rely on signals from other investors to validate their decisions.
• This tendency leads to the creation of “hot deals,” where startups attract more investor interest than they can handle. These deals aren’t necessarily the best opportunities; they simply benefit from amplified momentum.
Competitive Pressure
• As one investor progresses toward an offer, others may feel pressured to act quickly to avoid losing out.
• This urgency, while beneficial for founders, can create a frenzied pace that must be carefully managed. Investors who act under pressure may later experience buyer’s remorse, which can disrupt your fundraising efforts.
The Risks of the Herd Effect
While the herd effect can create valuable momentum, it also introduces several risks:
The Myth of the Stampede
• A stampede of investor interest doesn’t guarantee a strong company. Some startups that spark intense competition among investors fail spectacularly, often due to unrealistic expectations or poor execution.
• Conversely, many highly successful startups struggled to gain traction in their early fundraising efforts. Founders should focus on building a great business rather than orchestrating artificial hype.
Emotional Investors
• Investors, despite their professional façade, can be deeply emotional. Indignation is a common reaction when they feel slighted—for example, if they perceive they’re being offered less favorable terms than earlier investors.
• This emotionality can lead to irrational decisions, such as refusing to invest even when the opportunity aligns with their portfolio goals.
The Initial Barrier
• The hardest part of fundraising is often securing the first commitment. Until then, the lack of momentum can make investors hesitant. Understanding that this difficulty is external rather than a reflection of your startup can help maintain morale.
Create and Manage Momentum
• Leverage the first commitment to build momentum with other investors. Share your progress strategically, but avoid exaggerating or manufacturing interest.
• Keep the focus on your growth metrics, traction, and team capabilities—these are the ultimate drivers of investor confidence.
Be Transparent, But Strategic
• If you’re making progress with one investor but would prefer another, be transparent about the situation without naming names.
• Avoid exaggeration or artificial pressure tactics. Investors are highly attuned to manipulation and may lose trust if they sense dishonesty.
Don’t Over-Optimize for a Stampede
• Focus on securing strong, reputable investors rather than chasing a stampede. Over-optimization for herd dynamics can distract you from the core goal of building a sustainable business.
The Importance of the First Commitment
The first investor commitment is pivotal in fundraising. It not only provides the initial capital but also serves as a signal to other investors.
• Momentum Builder: Once the first check is secured, subsequent commitments often come more easily.
• Increased Confidence: Your confidence will naturally grow after the first commitment, and this will be evident in your interactions with other investors.
• Social Proof: Investors are more likely to engage when they see that others have already committed.
Strategies for Success
Emphasize Traction
• Highlight tangible achievements such as revenue growth, user acquisition, or partnerships. These metrics provide investors with concrete reasons to believe in your potential.
Set Realistic Valuations
• Avoid inflating your valuation in the early stages. A modest valuation can help attract early investors and build momentum, which you can leverage for subsequent rounds.
Protect Relationships
• Be respectful and professional, even with investors who decline. Rejections often stem from circumstances unrelated to your business, and those same investors may be open to funding you in the future.
Conclusion
The herd effect is an inevitable part of startup fundraising. By understanding the dynamics that drive investor behavior, founders can better navigate the challenges and opportunities it presents. While momentum is valuable, the ultimate goal is to build a sustainable, high-growth business that attracts investors because of its inherent value—not just the buzz it generates.
By focusing on genuine traction, transparent communication, and long-term relationships, you can turn the herd effect from a daunting challenge into a powerful ally.
