In the book Smart Startups, authors Catalina Daniels and James Sherman interviewed 18 entrepreneurs from Harvard Business School to uncover insights into what makes a startup succeed during the growth phase. The overwhelming consensus? It’s not just about having a good idea—it’s about executing that idea flawlessly.

The Crucial Role of Execution in Scaling

As startups grow, the gap between initial success and long-term viability often comes down to execution. Many entrepreneurs who find success in their early stages fail when it’s time to scale, because they underestimate the complexities that come with growth. From marketing to operations, technology, and logistics, scaling requires a solid system in place—something that many startups don’t anticipate.

Matt Salzberg, the former CEO of Blue Apron, recalls how his company struggled as they rapidly grew their customer base. “We lacked the required systems to manage operations efficiently,” he explains. This led to supply chain issues, delays in shipments, and frustrated customers. Their success, he says, was impaired by not having the right systems in place, which ultimately led to significant execution challenges.

Another example comes from Josh Hix, co-founder of Plated. He notes that scaling wasn’t just about selling ingredients or providing recipes; the real difficulty came from the operational intensity of managing logistics at scale. “It’s not just about one thing—it’s about handling all aspects of the business at high efficiency and quality,” he explains. From demand forecasting to packaging, shipping, and customer service, it was the sum of all these operations that created the most significant challenge.

Managing the Grind of Scaling

Scaling a startup isn’t a one-time sprint but a continuous grind. Entrepreneurs must balance the need to grow rapidly with the realities of managing a more complex operation. Salzberg warns that things will take much longer than anticipated. For founders without previous experience in scaling, this learning curve can be particularly steep, requiring patience and resilience.

Moreover, startup founders must also acknowledge that they will make mistakes along the way. While these setbacks can be discouraging, they are part of the process. The key is to keep grinding through the challenges and learn from each mistake. By doing so, you not only improve your systems but also create a competitive advantage that sets you up for long-term success.

Finding Your Competitive Advantage in Execution

While some startups succeed because of proprietary technology or unique intellectual property, most gain their competitive edge through effective execution. Rent the Runway, for example, built its success not just on its designer relationships but on logistics. According to co-founder Jenny Fleiss, logistics became their biggest competitive advantage as the company scaled. Managing complex supply chains and developing sophisticated data insights allowed Rent the Runway to grow into one of the largest dry-cleaning operations in the world.

The takeaway from this example is that, for many startups, execution—especially in logistics, operations, and customer service—becomes the true competitive differentiator. Fleiss emphasizes the importance of specialized labor in their warehouses, noting that a visual inspection of garments, something not captured by technology, is critical to maintaining quality standards. This focus on the details and the “sniff test” became crucial to their business model.

How to Ensure Effective Execution

While the hurdles faced by founders will vary, the path to success involves nailing down execution first. Entrepreneurs should be vigilant about which parts of the business can or should be their core competitive strengths. This clarity allows them to scale efficiently and avoid getting sidetracked by factors that don’t align with their long-term strategy.

Here are the key strategies for ensuring successful execution:

1. Focus on Scalability:
   Ensure that your systems—whether for supply chain management, marketing, or customer service—are ready to scale. The systems that worked during the early days may not be sufficient as the business grows.
2. Anticipate Complexity:
   As your startup grows, operational complexities will increase. Be prepared for the grind of managing these complexities and invest in systems that support long-term growth.
3. Learn from Mistakes:
   Don’t be discouraged by setbacks. Use mistakes as learning opportunities and adjust your approach accordingly. A failure today can be the stepping stone to success tomorrow.
4. Identify Your Competitive Edge:
   Understand what differentiates your business and invest heavily in that area. Whether it’s logistics, customer service, or proprietary technology, focus on making it a core part of your strategy.

Conclusion: The Long Road to Startup Success

Building a successful startup requires more than just a great idea—it requires the ability to execute that idea at scale. As many successful entrepreneurs attest, navigating the complexities of scaling requires an understanding of operations, supply chains, technology, and more. By focusing on execution, learning from mistakes, and adapting as you grow, you can set your business up for long-term success.

Remember that scaling is a marathon, not a sprint. By managing the grind of growth and ensuring that your business model is sustainable, you’ll be well-positioned to thrive in the ever-evolving startup landscape.

1. “Do What You Love and You’ll Never Work a Day in Your Life”

Michael Bosstick, founder and CEO of Dear Media, is quick to dismiss this well-known saying. While he acknowledges that doing what you love can help fuel the passion needed to build a business, he points out the inherent flaw in this advice.

Why it’s wrong:
“I’ve always done what I love, and it’s helped me build competitive brands and businesses. But it’s still hard work,” says Bosstick. “Managing a team or a business does not come easy. The nuanced version of this advice would be: ‘Do what you love, and you’ll be able to take on the hard work required to build a career or business.’ There’s no way around the hard work, even if you love what you do.”

This advice oversimplifies the reality of entrepreneurship. While passion is essential, success requires long hours, tough decisions, and resilience.

2. “Hire a Head of X Sooner Than Later”

Sean Knapp, founder and CEO of Ascend.io, warns against the advice to hire senior-level executives too early in a company’s growth. Many advisors and investors encourage hiring a head of marketing, engineering, or sales early on to scale quickly, but Knapp believes this advice can be detrimental to young companies.

Why it’s wrong:
“Most companies hire these positions too soon or hire from larger organizations where the executives can’t scale down effectively to the earlier stages of the business,” Knapp explains. “You often see these executives come in, followed by their ‘lieutenants.’ I prefer hiring the lieutenants and accessing later-stage leaders as advisors and coaches.”

Hiring too early or without considering the company’s specific needs can be a costly mistake. Knapp advocates for a more strategic approach to hiring, one that prioritizes flexibility and gradual scaling.

3. “Have a Great 30-Second Pitch”

Vicki von Holzhausen, founder and CEO of von Holzhausen, believes the focus on a 30-second pitch is misguided, especially for businesses with complex offerings. While brevity is often praised in the startup world, von Holzhausen explains that oversimplifying a business’s objectives is unrealistic.

Why it’s wrong:
“It doesn’t make sense to oversimplify complex business objectives. If it were simple, everyone would do it!” von Holzhausen says. “Our business takes a multipronged approach, and while it takes longer to understand, we focus on an audience that already cares about our values. We speak to the right circles, those who have the patience for a more layered story.”

Instead of focusing on a 30-second pitch, von Holzhausen advises a targeted, audience-focused approach that nurtures long-term engagement and reflects the depth of your business.

4. “Build an MVP”

Ryan Woodbury, cofounder and co-CEO of Needed, points out that for certain industries, especially those involving health or trust-based products, a Minimum Viable Product (MVP) is not always the right strategy. For example, when launching a product like prenatal vitamins, quality and safety are paramount, and launching with an MVP could put customers’ trust at risk.

Why it’s wrong:
“In categories where quality and consumer trust really matter, consider whether an MVP is truly the best approach,” says Woodbury. “In our case, the prenatal vitamin required a complete redesign. MVP wouldn’t cut it, and that extra work paid off because our prenatal is now renowned for meeting women’s needs optimally.”

This advice doesn’t apply universally. In some cases, rushing an MVP can damage the reputation of a brand and result in customer dissatisfaction.

5. “Fake It ’Til You Make It”

Kara Brothers, president and general manager of Starface, shares her experience with the saying “fake it ’til you make it,” which encourages individuals to act confident and knowledgeable, even if they don’t feel prepared. Brothers believes this mindset is not only stressful but ultimately counterproductive.

Why it’s wrong:
“I’ve always found ‘faking it’ much more stressful and less enjoyable than embracing what I don’t know,” says Brothers. “My journey as a leader involved a lot of self-doubt, but I found that asking questions and staying curious helped me grow.”

Instead of pretending to know everything, Brothers encourages leaders to embrace vulnerability and learn openly. Authenticity, rather than faking confidence, builds trust and fosters growth in leadership.

6. “Scale Revenue, and Everything Else Will Fall Into Place”

Nick Bodkins, cofounder and CEO of Boisson, challenges the common advice that simply scaling revenue will lead to success. Many entrepreneurs are urged to focus on scaling their revenue quickly, but Bodkins warns that focusing on growth alone can overlook the fundamentals of a sustainable business model.

Why it’s wrong:
“That’s what I was told for a while, but it’s not the reality,” says Bodkins. “Many brands have spent millions building themselves into household names, yet still can’t find profitability because their business model doesn’t work. We focus on understanding our levers and unit economics before scaling.”

Revenue growth without a strong foundation can lead to unsustainable business practices and long-term struggles. Bodkins emphasizes the importance of building a solid business model first, before scaling operations.

Conclusion: Rethinking Entrepreneurial Wisdom

While entrepreneurial advice is often shared with the best of intentions, not all of it stands up to scrutiny. As these successful founders and CEOs point out, some of the most widely circulated pieces of advice can actually steer you in the wrong direction. The best approach is to remain critical, ask questions, and apply lessons based on your unique business context.

Success as an entrepreneur requires more than just following conventional wisdom—it’s about finding what works for your business, learning from your experiences, and making decisions that are aligned with your long-term goals. So, the next time you hear a piece of advice that sounds too good to be true, take a step back and consider whether it truly applies to your business journey.
