Pros
Lots of opportunity to take ownership of projects from beginning to end with the autonomy to make high-level decisions. Because the team is so small, you get to know everyone really well. Even though it's a start-up there is still a good work-life balance. You have the option to work remotely a couple days a week and when otherwise needed. Stock options are offered to employees, and they are the same level of stock as the executives/board/investors. The office is nice and located next to the University Mall and lots of restaurants.
Cons
Typical early stage start-up cons. If you're used to being told what to work on, then working at IXN will be a struggle. For a while there wasn't very clear direction from the executives on the direction of the company, but that has improved dramatically. No insurance or perks besides working remotely. Pay isn't great, but that's kinda expected considering the infancy/size of the company.
