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.
