In the startup world, the phrase Product-Market Fit (PMF) is considered the holy grail of success. Angel investors and venture capitalists always ask first: “Do you have PMF?” So, what exactly is PMF, and how can a startup know when it has achieved it?
To achieve PMF, you must first build an MVP. Read our article: What is an MVP (Minimum Viable Product)? Validating your idea on a low budget
1. What is PMF?
Product-Market Fit is the state where a product satisfies a real and sufficiently large market demand, and customers are eager to pay for it.
In the words of Marc Andreessen: “PMF means being in a good market with a product that can satisfy that market.”
According to the benchmark survey developed by growth expert Sean Ellis, if at least 40% of surveyed users respond that they would be “very disappointed” if the product disappeared tomorrow, the startup has achieved PMF.
2. Key metrics for measuring PMF
- Retention rate: Are users returning to the product repeatedly? The retention curve should flatten into a horizontal line over time.
- Organic and viral growth (Word-of-mouth): Are initial customers organically recommending the product to their network?
- LTV > 3x CAC ratio: Maintaining a low churn rate with Customer Lifetime Value (LTV) being at least three times higher than Customer Acquisition Cost (CAC).
After reaching PMF, the scaling stage begins. Learn about scaling in our article: Scalability: Scaling and expanding into international markets. Spending heavily on marketing before achieving PMF is like pouring water into a leaky bucket. First find PMF, then scale.
