I'm a little confused about what the business model here is. It sounds like they are selling labeled data to companies, and doing this by "label[ing] most of the objects automatically" and then having humans review these labels. So does this mean they are using some unsupervised method to label data, and then selling that to people who want to train supervised models? Why aren't they instead just beating out the people they sell to by solving the same problems without labeled data?
