Who owns growth on a small team
Not "hire a growth lead." Assign the hat, make the ritual cheap, and give the whole team the shared language — then climb the maturity ladder from flying blind to compounding through an owned audience.

"Treat your startup as a growth team" raises an obvious question on a four-person company: who? The answer is not "hire a growth lead." It's assign the hat, and make the ritual cheap.
- Name one owner. One person is accountable for the funnel being instrumented, the dashboard being read, and the journeys being live. It can be a founder. It's a hat, not a hire.
- Make growth a standing ritual, not a project. The cadence: a 2-minute daily glance at alerts, a 30-minute weekly read of retention + journeys + ad spend, a monthly review of incremental lift (the extra conversions a change caused, above what would have happened anyway) and blended CAC (customer-acquisition cost averaged across every channel, paid and organic). A system that runs on a rhythm survives; one that runs on heroics dies the first busy week.
- Give the whole team the shared language. Everyone should know the North Star (the single metric that best proxies the value your product delivers) and what "activated" means for your product. When the same five numbers mean the same thing to everyone, you've already beaten most companies.
The maturity ladder most startups climb: flying blind (no data) → analytics installed but no one looks → someone reads a dashboard → the team acts on it automatically through lifecycle journeys → growth compounds through an owned audience and referrals. This course walks that ladder rung by rung; the goal is the top of it.
It's worth being honest about which rung you're on. The most common self-deception is believing you're on rung three because a dashboard exists — a fairer test is whether any decision changed in the last month because of it. If the answer is no, rung two is closer to the truth, and the measurement chapters are where your leverage is.

Growth is an engineering discipline
The single biggest mindset change: growth work looks like engineering work. The unit is a hypothesis, the deliverable is a measured result, and tactics are the output of the loop — never the input.
The machine you're going to build
The whole system on one page: three layers, one loop. See it (PostHog), act on it (Hogsend), own it (identity + ads) — and the division of labour that keeps it legible: PostHog detects, Hogsend acts, you decide.
