Pros
I worked at livefyre for a year and some change. I had a great time. Fantastic engineers, active learning environment, all the blah blah blahs that you get in startuplandia.... You can learn a great deal here and there's still some good people left, but things have and are a changin'....
Cons
I'm not going to go agro or list a bunch of things that are wrong, but there are. Long story short there is no "culture" here anymore, and there is no loyalty. The company and moreover CEO are in "buy me" mode and so are doing whatever they feel is necessary to attain that. You will be told you are irreplaceable one day and be gone the next these days. It's sad, especially to watch a bunch of people (20 - 30 in the past couple of months) who gave their heart and soul to the org and the job get dropped no notice, and to "save money" Immediately after a huge funding round. Eh, these are rich men playing rich men games. No matter how much they preach about whatever the heck it is they are preaching about goals, values, culture, etc. It means nothing. Know this.
