Some years ago, I was at a conference and attended a very interesting talk. I don't remember the title of the talk, but what stuck with me was: "It's no longer the big beating the small, but the fast beating the slow". This talk was before all the AI hype. Working at a big company myself, I think this has never been more true. I think the question is, how to stay fast.

And, to add to that, how to know when to slow down. Also, having worked at a big company myself, I think the question shifts towards "how to get fast" without compromising security, compliance etc.

this is generic startup advice (doesnt mean its not true). you level up a bit when you find instances where slow beat fast (see: Teams vs Slack)
