Plant identification apps can generate significant revenue from a small user base, as they cater to a specific audience willing to pay for their utility.

There is a significant difference between apps that generate high traffic and those that generate revenue, with only 40% overlap between the two lists of top apps.

The size of your user base can create network effects, making your product more valuable as more people use it, which is a powerful advantage in today's market.

It's important to evaluate startups based on whether they have a small number of users who truly love the product, rather than just a large user base.

While revenue is often the best primary metric, some startups may focus on active users, especially if building a large audience is a prerequisite for monetization.

Once you have a product that users appreciate, expanding your market becomes easier; starting with a niche can lead to broader adoption later.

The success of an app can hinge on fine-tuning; for instance, a fine-tuning exercise led to a million users signing up in just five days.

If your startup has strong network effects, focusing on active users may be more important initially, with revenue becoming a focus later on. It's crucial to define what 'users' means for your startup, as it can vary significantly. For example, having 100 users could mean they just signed up or that they actively engage with your product daily for about 10 minutes. The latter is a much more valuable metric.

It's easier for startups to begin with a product that a small number of users love and then expand from there, rather than trying to please a large audience from the start.
