Don't get fooled

5 mistakes operators make when choosing

Mistake #1 — Buying Amplitude or Mixpanel paid plans too early

Founders skip the free tier and lock into $2K/mo before product-market fit.

Fix: Start free on PostHog, Mixpanel, or Amplitude. Upgrade only when you hit the cap.

Mistake #2 — Skipping event taxonomy entirely

Autocapture tools feel fast, but the data gets noisy in 90 days.

Fix: Spend two hours defining your 10 core events before instrumenting.

Mistake #3 — Using GA4 as your product analytics

GA4 is built for marketing. Funnels and cohorts are painful.

Fix: Use GA4 for marketing, a real PM tool for product.

Mistake #4 — Buying three tools instead of one

Replay + flags + analytics as separate bills costs 3× more.

Fix: PostHog bundles all three on the free tier.

Mistake #5 — Treating product analytics as a board reporting tool

PostHog and Mixpanel show PMs what users do, not what it means for ARR.

Fix: Pair a PM tool with a founder/board layer like Fairview.

PostHog if you want replay and flags bundled. Mixpanel if you want the classic funnel UX. Amplitude if PM analytics depth is the priority.

How much should a startup spend on product analytics?+

Most pre-seed and seed startups should spend $0. Median Series A spend is $3,400/year.

Is GA4 enough for product analytics?+

How long does setup take?+

PostHog 30 minutes. Mixpanel 1 hour. Amplitude 1–2 hours. Pendo 2–4 hours.

What PM events should a startup track first?+

Signup, activation, key feature use, repeat usage, paid conversion, churn signal. Ten events is enough.

What if I outgrow the free tier?+

PostHog and Mixpanel both have transparent pay-as-you-go pricing past the free cap.
