There is so much that's missing from this. What about gathering tokens from customers vs. paying for social data feeds? How about canned services like 80legs?
Hmm yeah there are a lot of other things that I could write about. 80legs seem like another Scrapy type of SaaS? Not sure what you mean about gathering tokens from customers.
I've heard of companies that scrape on behalf of customers who will walk marketing people through the process of creating an API token to help mitigate rate limiting.
