• Written first, huddle second, meet last
  Default to a clear Slack post, huddle when a thread stalls, and meet only to make a real decision.

• Fast, but never sloppy
  Do the two-month thing in two weeks, then check the work—shipping errors is rework, not speed.

• Shape what we build, not just how we build it
  There's no playbook waiting for you, so write it—and bring the alternative, not just the objection.

  Fewer titles and layers; process is a guardrail where it counts, never the reason something didn't ship.

• No hidden agendas
  Numbers, misses, and feedback are shared openly and in real time, so you always know where you stand.

• High standards, genuinely fun people
  Take the work seriously and ourselves much less—high-performing and fun to be around is the hiring bar.

• Is this pace for you?
  Venture-scaled and on a steep trajectory, with intensity in spikes, fiercely protected flexibility, and faster growth than anywhere else.
