The primary profile subject is Ophelia, which is a YC-funded startup trying to address the opioid crisis. They did a Launch HN back in March: https://news.ycombinator.com/item?id=22570133. (I hope it helped!) The article tells how they successfully raised $2.7M at Demo Day. But the way the article is framed, titled, and mostly written, you actually expect a different outcome while reading it.
(Edit: I found one spot where the author describes the question she was interested in exploring. That seems more representative, so I've changed it to that for now. Better suggestions welcome.)
(Edit 2: since now people are reacting reflexively to the question "Is venture capital producing the kinds of inventions society needs?" in the title, I've reverted the edit. If someone can suggest an accurate and neutral title, we can change it again. The current title is both misleading and linkbait, which are both of the reasons why the HN guidelines ask for a title to be changed.)
