Gone now -- I don't remember the name (unless this was the fastest pivot ever recorded, it was not Glass Health, which currently has a now hiring ad up[1])

Hah, happened to see this mentioned in another comment today. It was FreshPaint, whose website includes this gem:

"You need to install ad trackers on your website to get the most out of ad platforms like Facebook and Google Ads. Ad trackers can create issues for healthcare marketers by sending visitor identifiers and health information to platforms that aren't HIPAA-compliant."

I'm sure they are good folks, but what an absurd premise. Something about the best minds of our generation selling ads....
