Which funnels growth teams should be targeting, by stage:

- seed: None - worry about P/M fit!
- series A: Signup/Invite/sharing funnels
- B: Activation funnel
- C+: Monetization funnel
- Big co: Reactivation and cross-sell flow to new products

Generalizing in a big way but reflects the evolving goals (and skillsets) of a startup as it grows

Seed/A startups have no users, so it's all about finding product market fit and growing top of funnel acquisition

Once that works, then it's about retention and monetization

This dynamic is also why:
- You can't drop a big co "growth" leader into a small startup, or vice versa, and expect that to work
- why growth teams have to be expanded over time
- what worked before might stop working as the business scales!
