PMF
/ˌpiː ɛm ˈɛf/
Definition
A state where a product satisfies market demand well enough that customers seek it out, recommend it, and pay for it on their own. Considered the milestone startups must hit before investing heavily in marketing and sales.
Examples
- • The common advice is: don't spend on ads until you've found PMF.
- • Our product is still validating PMF, so we're focused on user interviews rather than adding features.
Origin
The concept was developed by venture capitalist Andy Rachleff and named "product/market fit" by Marc Andreessen in his 2007 essay "The Only Thing That Matters," which popularized it across the startup world.
Description
PMF describes the moment a product fits the market it's built for. Marc Andreessen described it this way: customers buy faster than you can make the product, cash piles up in the bank account, and you can barely hire fast enough to keep up.
How to use it
- Before you have PMF, prioritize deep interviews with a small number of customers over adding features or scaling ads — the goal is confirming they have a real problem.
- Watch for tell-tale signals: organic word-of-mouth growth, customers who'd be genuinely upset to lose the product (in the classic survey, "very disappointed" responses above 40% are a good sign), and repeat usage or purchases that happen naturally.
- Spending on marketing before PMF just proves — expensively — that the wrong people are churning out.
