Does anybody store files in S3 for their SaaS?

Is anybody storing non-text files in S3 for their software? I'm referring to pdf, video, audio, images, etc.

If so, it would mean the world if I could talk to you and just ask about some of your experience with uploading/retrieving these files within your software.

To give context: I have a free managed API that offers full-text-search for your S3 bucket to integrate into your software.

Let me know if this matches you and if you're willing to answer some quick Qs in exchange to be involved in the free pilot :)
