Customers & Markets
How Any Startup Can Achieve Explosive Customer Growth
A structured way to test customer-acquisition channels instead of guessing, built around 19 channels and the Bullseye process.
The big idea
Most startups that fail had a product; what they lacked was a reliable way to get customers. Weinberg and Mares argue that traction deserves as much founder attention as building, and that the best channel is often one the team would never pick by instinct. They map nineteen ways companies acquire customers and offer the Bullseye, a process for brainstorming every channel, ranking the most promising, running cheap tests, and then focusing hard on the one that works until it saturates.
Key takeaways
The authors suggest founders spend roughly half their time on getting customers, in parallel with building, rather than finishing the product first. Working on distribution early tells you which features matter, shapes positioning, and avoids launching to silence. Traction work is not a later phase; it runs alongside product from the start.
The book catalogs nineteen channels, from SEO and content marketing to sales, business development, trade shows, and community building. Founders tend to try only the two or three they already know. Deliberately brainstorming how each channel could work for your business surfaces options you would otherwise ignore, and the eventual winner is often among them.
Before committing to a channel, run small experiments with limited money and time to answer basic questions: how much does a customer cost here, how many are available, and are they the right customers. The goal is to rule out weak channels quickly, not to build a polished campaign. A failed test is useful if it was cheap.
Once a test shows a channel can move your key metric, put most of your effort there and keep optimizing it. Spreading attention across many mediocre channels tends to produce mediocre results everywhere. Most companies that grow fast lean heavily on one primary channel at a time.
What works for your first hundred customers rarely works for the next ten thousand. Channels get more expensive as competitors arrive and as you exhaust the easy audience. Keep a small portion of effort testing the next channel before the current one stalls, so growth does not stop while you search for the next source of customers.
Building a free tool, calculator, or widget that solves a small, related problem can bring qualified prospects to you. It suits technical teams and tends to keep paying off after it launches. Few competitors try it, which leaves room for those who do, and the tool itself can demonstrate your expertise.
Define the traction goal that would change your company's prospects, such as the number of customers needed for profitability or a raise. Then list the milestones that must happen to reach it, in order. Anything not on that critical path is a distraction, which makes it easier to say no.
