If a product solves a rare problem, it may not have enough demand to sustain itself. Frequent problems, like workplace communication, are where real engagement happens.

Determine how frequently they encounter the problem, as more frequent issues indicate a higher likelihood of needing a solution.

If you can't even interview potential customers effectively, you're likely to struggle with acquiring your first customers.

To find urgent customers, look for those with pressing problems, as they are more likely to engage with and invest in your solution.

Choosing your customers is crucial; if you aim to attract anyone, you risk failure. Instead, focus on a specific audience and understand their needs and characteristics to shape your product effectively.

The usual reaction to a small problem is to consider ad revenue, but ads won't work if the problem is rare and users aren't engaged enough.

If you have a handful of happy customers but struggle to find new ones, it may indicate you're stuck at level one of product-market fit.

The problem you address should be significant and widespread, indicating a large market with many people affected by it.

Good problems are those that are frequent, mandatory, and have a large number of people affected, as these characteristics increase the likelihood of a startup's success.
