Pros
Fresh , dynamic , friendly , definitely a nice place to work and learn a lot of different technologies and skills. Developers have a rare opportunity to work on wide technology stack , like PHP , Java, Html , CSS , Bash , Ruby , Node.js. It s definitely a polyglot place where the technology serve to solve problems no matter what s about. Flat organisation. Interaction with the CTO and Managers or Investors really easy and direct. You feel free to express your opinion, provide contributions and/or criticism, they are quite open to listen and in case change.
Cons
A bit of lack of communication with the teams and a lack of process and methodologies sometimes made the daily work frustrating. Some personal concern about how some technology decision are taken, more on buzz words then real expertise and evaluation. Lack of process for employees evolution and no carrier path. Many developers left because they felt they were left behind or considered not that good.
