Don't get fooled

5 mistakes operators make when choosing

Mistake #1 — Buying enterprise attribution at seed stage

Founders see a Bizible demo and get sold on multi-touch depth they cannot operationalize.

Fix: Start with PostHog or HubSpot. Layer paid attribution only when ad spend justifies it.

Mistake #2 — Treating GA4 as primary B2B attribution

GA4 cannot tie a lead to closed ARR without CRM context.

Fix: Use GA4 as a baseline. Pair it with HubSpot or a dedicated B2B tool.

Mistake #3 — Skipping CRM-level source capture

Without UTM and source fields on Lead/Opportunity, no tool can rebuild source-to-ARR.

Fix: Set source capture on every form before you buy any tool.

Mistake #4 — Confusing financial attribution with marketing attribution

Source-to-ARR for the board is not the same as multi-touch for the marketer.

Fix: Pick a primary attribution tool (HubSpot/PostHog) plus a financial truth layer (Fairview) if you board-report.

Mistake #5 — Paying $1K+/mo before $1M ARR

Dedicated B2B attribution at seed wastes runway.

Fix: Stay free until you cross $1M ARR or $20K/mo ad spend.
