For me this question comes down to: What do you want to learn?

In a big company, most risk has been removed from the equation. This is great for compensation and stability but also limits ones possible learnings as well. You might find your time learning the big company’s systems which don’t apply universally because they’re specific to that company’s needs.

In smaller companies, risk is still a real aspect of life. The downsides are obvious but the joys are that you’re closer to the customer and your actions have real impact. I find these types of learnings to be universal which is why I’m drawn to it.
