Ask HN: What was the best 2016 Startup idea to re-think the recruitment process?

Why do we still have head-hunters in 2017? I thought 2016 was the year of disruption for HR related processes. Here is a sample of an email I just received and I still get a lot of those! "I'm working with a hot startup, they have a kick ass idea, series B, would you be interested?" No company name, so I can look it up, no clue about what they're working on. I'm left with a third party asking me the following question: "Are you interested?". Interested in WHAT?
