I went for an interview once at a hedge fund. There were a surprising amount of questions about web scraping. I very much got the feeling it was an active and ongoing problem. So yes I do think there’s a business in there.
AFAIK Plaid does a fair bit of old school scraping behind the scenes - a lot of the "nice new web" is built on the backs of old kludgy websites doing the same scraping things people were doing 20 years ago.
Finance/banks are especially... inconsistent, to say the least.
Having recently worked for a hedge fund I noticed that too - although my idea predated that engagement .
That's probably my first go-to market (if anyone has leads send me end email) .
Hedge funds actually call this "alternative data".
If you worked for a hedge fund and you know they purchase scraped data from quite a number of vendors then why are you asking if it’s a viable business model?
