Six years at one company, three weeks at a ten-person startup, and I still flinch every time someone says 'just ship it'

Old place had a review process with actual gates. Here 'ship it' apparently means it's live in production in the next twenty minutes, no staging environment to speak of. Nobody's died yet. I keep waiting for the part where someone tells me to slow down and it hasn't come. Trying to figure out if this is exhilarating or just reckless and I haven't been here long enough to tell the difference.
