Start to Scale: Secrets to Starting and Scaling Any Size Organization

This is one of those “field manual” books that founders either love or hate, because it forces them to operationalize. The point is simple: the growth stage is where companies break, mostly because the operating system never got upgraded (what worked from 0 to 1 rarely works for 1 to 10). The tools here are system-heavy (priorities, rhythms, execution discipline), but that’s the point: you can’t scale on vibes. If you’re past the inspirational phase (pre-seed/seed) and into “we need this to work every week” (Series A+), this is genuinely useful.
