Sell First, Then Build: Professor Vincent Onyemah on the First Rule of Startup Success
In the startup world, there’s often a tendency to focus on building the perfect product before thinking about how to sell it.
However, Vincent Onyemah, Professor of Sales and Marketing at Babson College, offers a different perspective. “Selling should come before building,” Vincent Onyemah asserts. With years of experience consulting for global organizations and educating future entrepreneurs, he has come to this conclusion: “Sales is not complete until you collect the money.”
Vincent Onyemah emphasizes that understanding your customer’s needs and validating your product in the market should be the primary focus of any startup. “Owning a technology is one thing; creating value is another,” he explains, stressing that a product is only valuable when it solves a real problem and when customers are willing to pay for that solution.
The Importance of Early Customer Validation
For many entrepreneurs, the focus is often on the product—getting the technology right, refining the user experience, and solving a technical problem. However, Vincent Onyemah warns that focusing too much on product development can blind entrepreneurs to the fact that they haven’t validated the core need for their product. Without understanding the customer’s pain point, even the best technology could go unused.
“Before you invest time and resources into building your product, you should be selling it. Speak to customers, understand their pain points, and see if your solution is something they will pay for,” says Vincent Onyemah. By engaging with potential customers from the start, founders can shape their product to fit actual market needs and ensure that they are not building something without demand.
He advocates for a “sell first, then build” approach, urging entrepreneurs to use customer feedback to shape their product. Early interactions with customers can help determine if the problem they’re solving is real and whether customers see enough value to invest in it.
Sales as the Lifeblood of Startups
Once a product is validated and customers show interest, the next critical step is generating sustainable cash flow. Vincent Onyemah believes that “customer revenue is the most vital form of capital” for any startup.
For many entrepreneurs, the focus often shifts to raising funds from investors or seeking loans. However, Vincent Onyemah stresses the importance of customer-driven growth. “The cash from customers is what validates your product. This is the revenue that sustains your business and builds credibility.”
When customers are willing to pay for your product, it signals that your solution has true value. According to Vincent Onyemah, “Once you have that validation, you’ll find it easier to attract investors, as they’ll see that there is a demand for your product.”
By prioritizing customer sales, startups not only validate their business but also create a solid foundation for future growth without being overly reliant on outside capital.
Building Relationships Through Trust
Vincent Onyemah emphasizes that sales is not just about closing deals but about building long-term relationships. Trust plays a key role in this process, as customers are more likely to return if they feel they are valued beyond the transaction.
“Trust is the best currency in business,” says Vincent Onyemah. Successful sales are built on consistent communication and genuine relationships with customers. It’s important for entrepreneurs to understand that “you need to continue the relationship even after the sale” in order to build customer loyalty and ensure long-term success.
This relationship-building mindset extends beyond the initial sale. He suggests that founders should regularly check in with their customers, ask for feedback, and ensure that the product is continuing to meet their needs. “Happy customers will become your best advocates and help you attract new business,” he adds.
Vincent Onyemah’s message to startup founders is clear: sales are the lifeblood of your business. It’s not just about making a sale—it’s about creating value, building trust with customers, and ensuring that the product is solving real problems. By focusing on generating revenue early on and prioritizing customer engagement, founders can build a sustainable and scalable business.
”Revenue is freedom,” he says, with a smile. The more you focus on generating revenue from customers, the more your business will thrive, independently of external capital, and with the confidence to scale. “When founders focus on customer-driven sales and building strong relationships, it can really help their businesses grow and succeed in the long run.
