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 FP&A at seed

Pigment/Anaplan demos sell on depth founders can't staff.

Fix: Pick a tool a founder runs alone.

Mistake #2 — Static spreadsheet forecast

A model that never updates is wrong by week 2.

Fix: Pick a tool with live data connections.

Mistake #3 — No runway view

Revenue without burn = vanity.

Fix: Tie ARR to burn and runway.

Mistake #4 — Skipping Stripe sync

CRM-stage ARR ≠ billing ARR.

Fix: Demand native Stripe.

Mistake #5 — Paying per seat at a 10-person startup

$50/seat × 10 = $6K/yr.

Fix: Pick per-account.
