Methodology

How we evaluated

This is a desk evaluation, not a hands-on test. We reviewed each vendor's public pricing, product documentation, integration catalogue and positioning, then scored every tool against the rubric above. Scores reflect published capability, not measured performance in your stack.

Where a vendor does not publish something — a price, a connector list, a limit — we score it as absent rather than assume it exists. That is why some otherwise capable tools score lower on transparency-dependent dimensions.

Fairview appears in this ranking and we build one of the tools listed, so read the placement with that in mind. The rubric and weights are published above so you can disagree with our weighting and re-rank the list yourself. We take no affiliate commission from any vendor here. Our full policy is at editorial standards.

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.

FAQ

Common questions

What is the best marketing attribution for startups in 2026?+

How much should a startup spend on attribution software?+

Median Series A spend is $1,900/year. Most pre-seed and seed startups should spend $0.

Is Fairview a marketing attribution tool?+

No. Fairview is a financial truth layer that ties source to closed ARR for board reporting. It does not do multi-touch journey modeling or ad pixel tracking.

PostHog vs HubSpot vs Dreamdata for a startup?+

PostHog at pre-seed/seed if you're product-led. HubSpot at Series A if you're already on the CRM. Dreamdata once you can spend $1K/mo on dedicated B2B attribution.

What about Bizible or Marketo Measure?+

Both are enterprise. Wrong for startups in any stage.

Do I need attribution before my first marketing hire?+

Set up free tooling (PostHog or GA4) on day one. Wait on paid attribution until you have a marketer running spend.

Source-to-pipeline, source-to-closed-revenue, CAC by channel, payback period, blended CAC, and channel ROI.

What if I outgrow the free tools?+

Move to HubSpot Marketing Hub or Dreamdata around Series A. Keep Fairview for the board layer.
