Ycombinator may have financially benefited from the scam operations since the company subsequently raised funds.
Considering they do due diligence before investment and are experts in IT and legal, how could they not know what is the business model when it was the unique selling point ?
Yeah, yeah... of course, of course... like telehealth companies prescribing GLP-1 Ozempic/Wegovy where there is one doctor for 10000 patients. Totally sounds legit.
