PMF IS A LAGGING INDICATOR. START WITH HABIT FORMATION INSTEAD

Summary from the TLDR Founders newsletter

Grant Lee argues that Product-Market Fit is a lagging metric and advises founders to focus first on whether they are building recurring habits rather than one-off solutions. By targeting frequent, low-friction problems and designing products that users invest in quickly, startups can create sticky behaviors that drive long-term engagement. Examples like Slack and Gamma illustrate how habit-focused design outperforms solutions that only address infrequent or high-friction needs.
