When we look at a successful company, it is easy to get distracted by the "shiny" parts: the proprietary software, the high-end manufacturing facility, or the impressive brand logo. We treat the business as an abstract monolith—a set of financial statements or a market share percentage. But from a first-principles perspective, a business is actually a machine or a product that has been assembled to achieve a specific result.
If you wanted to optimize a car to travel as fast as possible or carry the maximum amount of weight with the least amount of fuel, you would start by dismantling the machine. You would separate every gear, piston, and fuel line, understand what makes each piece work, and then reassemble it to be as efficient as possible.
In the Lower Middle Market (LMM), the ultimate objective for this "machine" is Durability and Profitability. While there are many ingredients you can pour into the business product—capital, processes, tools, strategy, and assets—there is one "center stone" ingredient that determines the effectiveness of every other component: People. This article explores the hierarchy of business components, the compounding "surprises" that come with high-quality talent, and the "vicious cycle" that traps many small businesses.
If we treat a business like a machine, our goal is to achieve maximum throughput with minimum friction. To optimize any machine, you have to understand the specific contribution of every part. Imagine you are building a high-performance racing car. You wouldn't just "wish" for more speed; you would analyze the engine, the aerodynamics, and the tires. Once you identify which component is the most critical for speed, you would find the best possible version of that part and prioritize its placement in the machine.
You can apply the same logic using a "cake" analogy. If you are baking a cake and your objective is to make it as sweet as possible, you identify the ingredient responsible for sweetness: sugar. While flour, eggs, and water are necessary for the structure of the cake, they don't contribute to the sweetness. Adding more eggs won't make the cake sweeter. To achieve your goal, you find the highest quality sugar available and you maximize its presence in the recipe.
If we think about a business as a product we are building, we have several "ingredients" at our disposal:
In the LMM, the end objective is a durable, profitable machine. While capital and assets are the "flour and eggs" that provide the structure, People are the "sugar." They are the ingredient that determines whether the final product actually achieves its goal.
The reason people are the most important component is a concept often overlooked in traditional business education: People are the source of every other ingredient. At the end of the day, a business is a collection of human decisions. If you want to enhance the quality of any business outcome, the most direct and sustainable way to do it is by improving the people connected to that outcome.
Everything starts with people. If you show me a business with a broken process or a failing strategy, I will show you a "people problem" masquerading as an "operational problem." When you improve the human component through training, mentorship, and development, you aren't just improving a single person; you are upgrading the "source code" of the entire machine.
When you recruit a "Wonderful Person" into your LMM business, you aren't just hiring a set of hands to perform a task. You are acquiring a "collection of experiences" and a "vortex of potential" that brings massive, often unexpected, upside surprises.
This is a "buy one, get a million free" deal. A great person brings their friends (The Talent Vortex), they improve the culture (The Lubricant), and they solve problems before you even know they exist. This creates a snowball of positive outcomes. Better people lead to better products, which attract better clients, which generate more financial resources, which allow you to attract even better people. Once this snowball starts rolling, it becomes the most durable competitive advantage a small business can have.
There is a common misunderstanding that large businesses are "hard" and small businesses are "easy." In reality, the Lower Middle Market is "Hard Mode" for business operations. Because larger businesses have massive structural advantages, they can actually afford to be less rigorous with their people.
Lower Middle Market businesses operate at a constant disadvantage. They have fewer resources, less brand recognition, and a much smaller margin for error.
Many LMM businesses find themselves trapped in a "Vicious Cycle" that starts and ends with the people ingredient. If you don't understand the physics of talent, you will find yourself in a downward spiral that is nearly impossible to escape.
Breaking this cycle requires a radical shift in mindset. You must realize that "People" are not an expense to be minimized; they are the primary component to be optimized.
If people are the most important component in the machine, then "People Engineering" is your most critical task. You cannot just hire someone and hope for the best. You must use specific "enhancers" to maximize the throughput and efficiency of the human component.
Training is the act of aligning a person’s skills with the machine's requirements. In the LMM, mentorship is often the only way to pass on the "tribal knowledge" that makes the business work. When you develop a person, you are increasing the "RPMs" of the entire machine.
People respond to incentives. If your incentives are misaligned, your best people will work toward the wrong goals. Great incentives—such as profit-sharing or performance bonuses—ensure that the person’s personal success is perfectly synchronized with the business’s durability.
Culture is the "lubrication" that reduces friction between the parts of the machine. In a high-trust culture, people can move faster, take risks, and communicate honestly without fear. A bad culture is like sand in the gears; it makes every process slower and more painful.
You cannot build a high-performance engine out of low-grade scrap metal. High compensation is how you ensure you are attracting the highest-grade "material" to your business. In the LMM, paying "above market" for an A-player is actually a discount because of the massive multiplier effect they have on your other resources.
For an investor evaluating an LMM acquisition, or an operator looking to improve their firm, your audit must start with the people. You aren't just looking at the cash flow; you are looking at the human record that produced it.
If you find a business with great outcomes, you will always find a "People-First" culture behind it. If you find a business with poor outcomes, the first thing you should do is look at who is sitting in the seats, not what is written in the spreadsheets.
One of the most beautiful parts of focusing on people is the unexpected positive surprises. When you hire someone wonderful, they continue to surprise you to the upside long after the onboarding process is over.
Because LMM businesses are smaller, the "People Ingredient" is more concentrated. In a 10-person firm, one bad hire is 10% of the company. In a 10,000-person firm, one bad hire is invisible.
In the Lower Middle Market, people are not a "support function" or a "line item." They are the primary component of the business machine. They are the ingredient that determines whether the cake rises or falls. While larger businesses can afford to take talent for granted, for an LMM firm, a "People-First" mindset is mission-critical.
The quality of your people is the ultimate predictor of your business’s success. If you want to turn a business around, don't start with the capital or the tools—start with the people. Build a "Talent Vortex," lean into the compounding surprises of great hires, and treat your team as the "center stone" of your organization. Show me the quality of the people, and I will show you the quality of the business outcomes.
