In today's fast-paced business world, finding the perfect product/market fit is essential for sustainable growth. The concept of product/market fit refers to the satisfaction level that allows for continued expansion and success. However, it's important to note that customers are inherently discontent. Their expectations are always on the rise, and what was once considered exceptional quickly becomes the norm.

In today's fast-paced business world, finding the perfect product/market fit is essential for sustainable growth. The concept of product/market fit refers to the satisfaction level that allows for continued expansion and success. However, it's important to note that customers are inherently discontent. Their expectations are always on the rise, and what was once considered exceptional quickly becomes the norm.

Contrary to popular belief, product/market fit is not achieved when customers stop complaining or when they are fully satisfied. In fact, customers will never stop complaining, and they will never be completely satisfied. Instead, product/market fit is achieved when customers stop leaving. Retention, rather than satisfaction, is the best indicator of whether a product is meeting the needs of its target market.

To measure product/market fit accurately, it is crucial to look beyond retention alone. While retention is a significant factor, it must be coupled with sustainable growth. This means that the rate of retention also plays a vital role. A flattened retention curve of the key action at a designated frequency, along with month over month growth in new customers, is the ultimate measure of true product/market fit.

When it comes to determining how long a product should stay in the initial phase of development, there are two main schools of thought. The Eric Ries model emphasizes the importance of early and frequent customer feedback to understand their pain points and build something valuable. On the other hand, the Keith Rabois model prioritizes the founders' vision and places less emphasis on customer feedback.

The Ries model focuses on targeting specific customer segments and addressing their problems to create a valuable solution. In contrast, the Rabois model starts with a strong vision of both the problem and the solution and works towards building it from the start. In the Ries model, the goal of launching a product is to generate feedback from the target customers. In the Rabois model, the goal is to bring the initial vision to life.

It is worth noting that successful products often have a strong vision that guides their development. Even major pivots are often driven by a new vision from the founders. While the Rabois model implies that product changes may be more difficult, it also suggests that relying on product change to drive growth can be costly. The Ries model is commonly seen in enterprise businesses, where founders are confident that specific segments have unresolved problems and are willing to pay for a reliable solution. The Rabois model, on the other hand, is more prevalent in hardware and consumer models, where founders need to convince a broad market to adopt new habits or interactions.

In my opinion, a combination of a strong vision and market feedback is the most effective approach to achieving product/market fit. However, it is important to consider the unique characteristics of the product being developed. Different axes may come into play depending on the nature of the product.

Ultimately, the key indicators of product/market fit are flattened retention curves every month and an increase in new user numbers within a healthy payback period. When these factors align, you can have confidence that your product is meeting the needs of the market.

To ensure that you are on the right track towards achieving product/market fit, here are three actionable pieces of advice:

1. Prioritize customer feedback: Whether you adopt the Ries or Rabois model, customer feedback is crucial. Regularly engage with your target market to understand their pain points and refine your product accordingly.

2. Stay true to your vision: While customer feedback is essential, don't lose sight of your initial vision. A strong vision can guide your product development and inspire customers to rally behind your brand.

3. Monitor retention and growth: Continuously track your retention rates and evaluate your new user numbers. A flattened retention curve, coupled with consistent growth, is a strong indicator of product/market fit.

In conclusion, finding product/market fit is a journey that requires a combination of market feedback and a strong vision. By understanding the dynamics of your target market, listening to customer feedback, and monitoring key indicators, you can position your product for sustained growth and success in the competitive business landscape.
