Product-Market Fit, or PMF for short, is a concept created by Marc Andressen, founder of Netscape and a Silicon Valley investor. This definition, coined by the investor, refers to understanding and measuring the level of customer satisfaction with a specific product in a specific market. According to Andressen, having good Product-Market Fit means great opportunities to be present in a strong market and to offer products that address the specific needs of the product\'s submarket. This product offering should leverage the buyer persona\'s problems. You can use this concept as a mapping tool, specifically for positioning your brand in the market. This allows you to establish consumer needs and how your company\'s product will meet them. PMF is fundamental in guiding a company toward an agile and optimized path. One of the important things to consider is that the product needs to be positioned in the right market, so that sales don\'t hinder the initial plan. Difficulty in making sales or a lack of target audience can be signs of the absence of a Product Lifecycle Management (PLM). To begin defining your PLM, you need to know the specifications of your audience. With a well-defined Buyer Persona, you will be able to understand the needs and preferences of your audience. A tip for analyzing your PLM is to establish a connection with your consumer or target audience. Additionally, you need to have benchmarking metrics. For this, you can use Customer Lifetime Value, which will allow you to know the average profitability of your company. It is necessary for the entire company to be aware of audience behavior. You should aim for your brand to be seen as valuable compared to the competition and customers. Conduct research and, above all, guarantee a positive user experience.
