Getting your first customer is a milestone. Finding a repeatable, profitable way to reach the next hundred is a different challenge—and the business model you choose can make that challenge easier or considerably harder.
In this episode of Start. Scale. Exit. Repeat., Colin C. Campbell and Michele Van Tilborg explored how to choose a scalable business idea, what actually holds companies back from growing, and where AI can help. Drawing on their experience with schools, e-commerce, office space, and domain names, they offered a practical reminder: understand what growth will require before you commit to the business.
Before you commit to a business idea, understand what it will take to grow it.
What Makes a Business Idea Scalable?
A scalable business can increase revenue without requiring the same proportional increase in costs, staffing, or infrastructure. That does not mean growth is free. It means the business has room to serve more customers without rebuilding its operations every time demand increases.
Colin shared the example of the Montessori school he owns with his wife. Once the school reaches capacity, enrolling more students could require additional property, construction, approvals, and employees. The school can be a successful business, but expansion involves a significant investment.
An e-commerce company has a different growth equation. It can reach customers beyond a single location, but inventory, financing, fulfillment, and advertising can become constraints. A digital business may avoid physical inventory altogether while still requiring substantial investment in development and distribution.
The question is straightforward: What will you need to add, spend, or change to serve more customers?
Demand, Execution, and Distribution Come First
Michele brought the discussion back to three fundamentals: Do people want the product? Can you deliver it? And can you reach the people who will buy it?
A business can look highly scalable on paper and still struggle with any one of those questions. Software may be inexpensive to distribute, but that advantage means little if customers do not understand its value or never discover it.
At Paw.com, Michele explained, the challenge has been finding efficient ways to acquire customers in a changing digital advertising environment. Having a product people want and the operational ability to fulfill orders does not automatically create a profitable path to growth.
That makes customer acquisition part of evaluating the idea itself. Before investing heavily, consider where customers already spend time, how you can reach them, and whether the economics work after accounting for marketing, delivery, and service.
Build a Repeatable Way to Reach Customers
The discussion became especially practical when a community member described his son’s translation app. It had attracted a paying customer, but finding additional subscribers was proving difficult without a large marketing budget.
The hosts suggested testing several ways to build awareness, including useful content, relevant communities, partnerships, and creators whose audiences could benefit from the product. Michele also emphasized that founders often need to become their company’s first salesperson.
For a translation app serving people in multilingual relationships, that could mean sharing helpful advice about communicating across language barriers. The content gives potential customers a reason to engage while demonstrating an understanding of their problem.
Colin summarized the approach in three words: buzz, distribution, and expertise. None guarantees immediate traction, but each gives a founder something concrete to develop and test.
Use AI With People Who Understand the Work
AI can help entrepreneurs research ideas, build prototypes, analyze information, and automate repetitive tasks. During the conversation, however, Michele challenged the suggestion that founders can simply hand everything over to AI and expect the business to grow.
Her experience points to a more practical approach: work with people who understand their field and know how to use AI effectively.
An advertising specialist still needs to understand customers, campaign performance, and profitability. AI can help that person analyze data and work more efficiently, but someone must decide what success looks like and whether the results justify the spending.
For founders, the opportunity is to apply expertise more effectively across the business. AI can support execution, while experienced people provide the judgment needed to evaluate its output and make decisions.
Prepare the Customer Experience for Growth
Scalability also depends on what happens after someone discovers your product.
One community member described a platform founder who was improving onboarding while the business was still small. By listening to feedback and simplifying the experience, the founder was addressing problems before a larger audience encountered them.
That is useful work at any stage. If customers struggle to get started, need extensive individual support, or encounter inconsistent service, additional sales can put more pressure on the business.
Early customer feedback helps founders identify those problems while they are still manageable. Improving the experience can make the product easier to recommend and the business better prepared to grow.
Choose a Business You Can Compete In
Highly scalable businesses can offer substantial opportunities, but they can also attract competition from around the world. A digital product that is easy to distribute may also be easy for someone else to copy.
Alongside scalability, consider what gives the company staying power. That might include customer relationships, distribution partnerships, original products, a trusted brand, or specialized expertise.
Colin’s advice was to “pick an idea you can win at.” A local service business or consulting firm can be a strong choice when it fits your skills, resources, and goals. The important step is understanding its constraints and deciding how you will work within—or eventually overcome—them.
Before launching, ask what growth would demand from your money, your team, and your time. A scalable business idea becomes more valuable when you also have a credible plan to attract customers, serve them well, and keep improving.
