They don't describe themselves that way, for sure. But the business model is to take lists of email addresses of variable quality, then to wash those lists through a validation service, then send to them through an ESP. The only value of the validation service here is to hide the quality and provenance of the list from the ESP. It doesn't change anything else. That's typically behaviour from a marketer who doesn't think the ESP would continue to work with them if they saw the quality of their lists.
