Chris Koerner ranks side hustles from AI implementation to day trading

AI implementation takes the top spot

Chris Koerner identifies AI implementation as the premier opportunity in today's market. This S-tier business model thrives on its extreme approachability; tools like Zapier allow individuals to automate business processes without significant capital investment. The value proposition is clear: you solve a business owner's efficiency problems using free or low-cost trials, then transition into a model of high upfront fees paired with recurring monthly retainers. It rides what Koerner calls a tidal wave of technological adoption.

Why day trading and content creation fail the test

On the opposite end of the spectrum, day trading and content creation are categorized as traps driven by survivorship bias. In day trading, the most visible successes are often individuals selling courses rather than those profiting from the market. The statistical probability of loss is remarkably high, making it a poor choice for long-term wealth management. Similarly, while the YouTube and TikTok algorithms showcase winners, they obscure the thousands of creators who fail to achieve consistency or monetization after years of effort.

Traditional service models offer hidden resilience

Unexpectedly, service-based businesses like window washing and car detailing receive high marks for their ability to build fundamental business skills. These models allow an entrepreneur to be in business for as little as $20, teaching the essential traits of resilience and rejection handling. Chris Koerner notes that while these may be harder to scale than digital businesses, they offer immediate cash flow and a tangible service that software cannot yet replace.

The logistical pitfalls of ATMs and vending machines

While often touted as passive income, ATMs and vending machines carry significant logistical burdens. Success is entirely dependent on location, and finding a high-performing site often requires significant capital to test multiple spots. Furthermore, the trend toward a cashless society creates a long-term headwind for ATMs. Investors looking for truly passive growth may find the capital requirements and site-selection risks higher than the projected returns.

Sustainable growth through skill acquisition

Ultimately, the best businesses are those that function as a power law game where 5% of participants capture 95% of the value through formulaic effort. Real estate and solar sales fall into this category. These roles require professional licensing or high-ticket sales training, creating a barrier to entry that rewards those willing to put in the work. By focusing on ventures that build transferable legal and sales skills, you ensure that even if a specific business fails, your personal human capital remains at an all-time high.
