Sounds neat, but is a subsidiary of EA really considered a "start up"?
That being said, I do think we (EA2D) have a lot in common with later-stage startups. Three big factors are our autonomy (near-complete), self-sufficiency (product, dev, marketing, ops, etc. is internal to our studio) and size (just 27 people across all disciplines). I bet our stack more closely resembles that of a startup than that of an enterprise.
