Ask HN: HR startups doing interesting work?

I work in HR Tech and the market is dominated by big enterprise HR Enterprises like Oracle, SAP, Workday or ADP. I couldn't a centralized list of HR startups that are doing nice and interesting work.

I was inspired by this post: https://news.ycombinator.com/item?id=21325138

It's a startup that provides a combo of Triplebyte + WeWork + Zenefits for hiring distributed teams.
