Work life balance is good. It really depends on your position. I don't know a lot on the eng side but marketplace is not doing well, they recently cut over 300 people between q4 2018 and q1 2019. You'll be ok for the next year or so if you're in a sales for our industry solutions side because it's their current focus. If you want to be with a company when they go public I guess Houzz is a good opportunity.
Btw, you won't get stock. They stopped giving it away 2-3 years ago.
Evidence ? Lol this is blind. I interviewed there and you can tell a lot by doing an onsite. Their interviewers seemed clueless and yet condescending. Aside from furniture recognition they're a boring e-commerce site (yes Glassdoor is too I know). I felt like it was a shitty company, you might think otherwise. Best of luck!
