Always glad to see success stories. But some stuff does not check out.

> Over 550 million people have used Zamzar since launch,

There are 8.3 billion people on earth. You are saying that about 1 in 42 have used your service? I had never heard of it and I don't know anybody who had. And that's a sample that should be biased in your favor. Sorry, does not pass the smell test.

Or maybe they were not unique visitors, containing duplicates? How many? This makes me skeptical of the remaining statistics on the page.

> converting over 766 million files. We now process over 1 million API requests per day.

1 million per day now and 766 million over 20 years? At the current rate you'd achieve that in about 2 years. This would indicate a rapid growth in the last couple years or even just months. It is unclear why that would be reasonable. Especially since you'd probably have emphasized this explosion more if your service was essentially dormant for 19 years and just recently went through the roof. (Sth like "how we handled 100x growth of our SaaS business over 3 months")

After these two data points I stopped reading. Something doesn't feel right.

Each file should be represented by at least three API requests, one to upload the file, one or more to check whether it's done, and one to download it. Together with the other calls of their API, I'd guess a files-to-API request ratio in the order of 1:10 rather than 1:1.

Looking at their website they support file uploads and API. They probably count those separately.

The numbers make sense to me, because I assume an API is used for high volume processing by other businesses and manual upload of files is done by individuals

They may have been inaccurate in their description, but that's what happens when regular people write articles and not scientists, engineers or LLM
