Product-market fit for startups refers to the point at which a startup's product or service meets the needs and wants of its target market.

It means that the startup has found the right product-market combination that will drive sustainable growth. It's the stage where a product or service is successful with a specific target market, and the startup can start scaling up.

Achieving product market fit is crucial for startups, as it's often the point at which a business can start generating revenue and attracting investment. To achieve product-market fit, startups often focus on customer discovery, testing, and validation to ensure that their product or service is meeting the needs of their target market.
