Building Growth Systems That Scale

Sustainable growth comes from systems, not heroics. That means a single source of truth for data, clear ownership of metrics (acquisition, activation, retention, revenue), and tooling that lets you experiment without breaking production.
We structure growth around three layers: instrumentation (events, identity, attribution), analysis (dashboards, cohorts, funnels), and execution (campaigns, experiments, automation). Each layer feeds the next; gaps in one layer limit what you can do in the others.
Start with one north-star metric and one primary funnel. Instrument it end-to-end, then add experiments. Only then layer in automation and AI. Teams that skip instrumentation end up optimising in the dark.
Finally, growth systems scale when the team structure matches: growth engineers who own the stack, growth marketers who own strategy and creative, and a shared language around metrics and experiments. That’s how you go from tactics to a repeatable growth engine.
