A pro for some may be a con for others. It is a startup. Expect work-in-progress processes and systems. I myself love being in a space where I can be part of the work-in-progress processes and help shape them but that's not everyone's cup of tea. Bottom-line, you need to be a self-starter and someone that enjoys and takes ownership of your work to thrive here. Otherwise you may feel misaligned. They do make that clear in their mission statements and it shouldn't be taken lightly.
