The concept of product-market fit (PMF) is crucial for startups and established companies alike. PMF refers to the alignment between a product's features and market demand, ensuring that the product satisfies the needs of its target audience. Intercom, a B2B SaaS company, recently developed the "PMF Panel" approach to identify and validate PMF for their Tickets feature. The panel consists of a small, representative group of potential customers with specific needs that the product was not yet able to meet. By creating this panel, Intercom aimed to better understand its target market's requirements and make data-driven decisions to improve the product. The approach has proven successful in refining the Tickets solution based on customer feedback, leading to a broader appeal among prospects. This technique can be applied to any mature product looking to expand or improve, making it a valuable method for achieving product-market fit.
