Interesting. I haven't seen the article, but if it says what you say it does then I think they've got it wrong.
To be clear, I'm not saying that an MBA student or an aspiring artist can't decide to start a home cleaning business and sign up with our service.
I'm no longer with the company, but I will say that the entire time that I was there, at no point was our business model based on recruiting/training unexperienced people to fill our verticals. In fact, our biggest worry was getting enough high-quality experienced providers.
I'm not privy to future plans, but currently any recurring work is just an added benefit to our service providers.
