Pretty surprised all these savvy investors that do due diligence before investing didn't see Zenefits' reliance on ADP as a gigantic risk. With 500M you should be able to build a better ADP to some degree but still, makes me wonder how much independent thinking goes on in the VC world right now. Feels like a company with a YC stamp of approval getting a free pass in the valley. Anyhow, I hope its sorted out as I actually really like the tenants of Zenpayroll.
