Casey’s Guide to Finding Product/Market Fit: Combining Insights on Satisfaction and Growth

Finding product/market fit is a crucial step for any product person. It involves connecting people to the value of a product once it has been confirmed that the product is delivering value. But what exactly is product/market fit? It is the level of satisfaction that allows for sustained growth. However, it's important to note that customers are never fully satisfied. Their expectations are constantly changing and evolving. As humans, we have a voracious appetite for a better way, and what was once considered extraordinary quickly becomes ordinary.

To measure product/market fit, it's not enough to simply measure customer satisfaction. Instead, measuring retention is the best signal of whether you have achieved product/market fit. When customers stop leaving and instead continue to use your product, it indicates that you have found a fit between your product and the market. But retention alone is not enough. It has to be accompanied by sustainable growth. This means that the rate of retention matters. A flattened retention curve of your key action at the designated frequency, along with month over month growth in new customers, is the best way to measure true product/market fit.

Now, let's explore two main schools of thought when it comes to finding product/market fit: the Eric Ries model and the Keith Rabois model. The Ries model emphasizes the importance of talking to customers early and often to understand their pain points and build something valuable. On the other hand, the Rabois model starts with a strong vision of a problem and a target solution and works towards building that vision. The goal of a launch in the Ries model is to generate feedback from the target customer, whereas the goal in the Rabois model is to achieve the initial vision.

In my opinion, a combination of these two approaches is often the most effective. A strong vision combined with market feedback can lead to great success. However, it's important to consider the unique characteristics of the product you are building. For example, the Ries model is commonly used in enterprise businesses where founders are confident that certain segments have unsolved problems. On the other hand, the Rabois model is more common in hardware and consumer models where founders need to convince a broad market to try something new.

One key aspect to consider in achieving product/market fit is the retention curves and new user numbers. If the retention curves flatten every month and new user numbers increase at a healthy payback period, it's a good indication that you have achieved product/market fit. This combination of retention and growth is a strong indicator that your product is resonating with the market.

Let's now shift our focus to the insights from a Japanese article titled "起業家たちの思いを受け継ぐクラブハウス｜石ころ｜note" (Note: The article is not mentioned as a reference, but its insights are being incorporated into the article).

The article highlights several key findings and learnings. Firstly, it emphasizes the importance of having a simple and powerful statement for your product, as well as removing any uncertainties or doubts. Clarity is key, and your statement should be something that users can easily understand and articulate.

Secondly, the article suggests that analyzing growth data by clustering users and understanding their lifestyle changes can provide valuable insights. For example, understanding the transition from high school to college can help identify patterns in user behavior. This analysis can help identify potential challenges and opportunities for retaining users.

A unique insight mentioned in the article is that business professionals, unlike teenagers going through significant environmental changes, have less variation in their social graph. This suggests that the social connections of business professionals are less likely to change, leading to a higher likelihood of user retention.

The article also highlights the value of Silicon Valley and the collective knowledge and experience of individuals who have created consumer apps and gained a deep understanding of the market. This collective knowledge is invaluable and contributes to the unique value of the region.

In conclusion, finding product/market fit is a crucial step for any product person. It requires a combination of satisfaction and growth. Measuring retention and sustainable growth is the best way to determine if you have achieved product/market fit. Additionally, incorporating insights from both the Eric Ries and Keith Rabois models can lead to a more comprehensive approach. Finally, analyzing user data, understanding lifestyle changes, and leveraging the collective knowledge of the industry can provide valuable insights and contribute to the success of finding product/market fit.

Actionable advice:

1. Continuously measure retention and analyze the growth of new users to determine if you have achieved product/market fit.
2. Incorporate a strong vision for your product while gathering feedback from your target customers to ensure you are building something valuable.
3. Utilize data analysis to understand user behavior and lifestyle changes, which can provide insights into potential challenges and opportunities for user retention.
