Are there any well-known companies that focus on data set collection and provision? Not talking HuggingFace like but more of highly curated data of best quality and guaranteed ownership rights (hard part about it!), where money for its usage is charged. I feel like there is a rapidly growing market for that with the advent of large foundation models and regulators stepping in, also and in particular bringing data privacy up.
These are web scraping services. Data ownership is a grey zone at best, depending on which country you're in. Besides, copyrighted data might be scraped by accident. What I am proposing is much stronger than that, rather like an "audited" dataset that comes with guarantees because its curation can be fully backtraced.
