You're a Series A+ SaaS doing complex scenario modeling, your accounting is on QuickBooks/Xero, and you have a finance person who can spend a few hours/week in a modeling tool. Causal's formula engine is excellent — but it doesn't integrate Razorpay, Cashfree, or Tally, and the pricing escalates fast.
You're a US-incorporated startup at Series A+ with $500K+ ARR, $500–1,000/month is a rounding error, and you want FP&A-grade reporting for your American board. Not built for India — no INR-native modules, no Tally/Razorpay/GST handling.
You're a mid-market company with a multi-person finance team, you want enterprise FP&A, and you're comfortable with sales-led onboarding. Overkill for <Series B startups.
You're an early-stage startup at pre-seed → Series A — your money flows through Stripe, QuickBooks, or Razorpay/Tally/Zoho Books — you want a CFO dashboard without a CFO bill, and you want to draft your monthly investor update in two minutes instead of two hours.
