Pros
There are some great people at ZL. Working with many of the energetic and lively people there was a pleasure. This company is very flat, everyone reports either to the CEO or the CTO, or the office manager who is the CEO's wife. The CTO is a competent engineering leader.
Cons
Other than the CTO the senior leadership is not great. Pennywise and pound foolish is the perfect description of the culture and style that pervades here. In its entire history this company has never managed to keep any non-founding member of the executive team for more than 18 months, not a VP Marketing, not a VP Sales, not a General Counsel. These execs are not all wrong. The 90% turnover, year over year in sales and marketing is also an indication of trouble emanating from the top.
