How this list is made
At least 20K estimated visits in the month and 10K the month before, positive growth, and at least three months of history. The ten with the highest growth are shown.
Visits are estimated monthly website visits across all channels, from third-party traffic panels, rounded to two significant figures. They are estimates, not numbers the companies report.
Growth compares the month with the month before. A company that runs several domains is counted once, with its domains added together, so a move from one domain to another does not show up as growth.
Companies are included when our classifier is confident AI is the product itself, not a feature of a wider platform. Adult and companion apps are left out. A reviewed list corrects wrong names and keeps public companies off the startup lists.
The list is rebuilt once a month, when the month's traffic estimates are in. A fast month can reflect a launch, a press cycle or a single viral post, so treat a place on this list as a reason to look closer, not as proof of revenue.
