Sigma Computing
Pros
- + Spreadsheet formulas and pivots compile to SQL and run live on the warehouse — no extracts to refresh, and I watched generated SQL hit Snowflake while filtering
- + Input tables and forms enable write-back: users enter forecasts or annotations that persist as first-class tables next to warehouse data
- + Permission-driven tiers are documented exactly (View/Act/Analyze/Build, billed at highest permission), so the licensing logic is knowable before the quote
- + Zero-dollar Viewer seats on AWS Marketplace make dashboard-consumer rollouts economically plausible
- + Live connections to the major warehouses (Snowflake, Databricks, BigQuery, Redshift) with materialisation and SQL/Python at the Build tier
Cons
- - No published list prices anywhere — sigmacomputing.com/pricing is a contact form; budgeting starts with a sales call
- - No free plan: a 7-day direct trial (20 invitations, 50 exports caps) or 14 days via AWS Marketplace is all a buyer gets
- - Tier escalation is silent: one Build-level permission on an Analyze account flips that user to Build pricing
- - Warehouse compute stacks under every interaction and can approach the licence cost — total spend is not visible in the quote
- - Excel veterans face a real recalibration: calculated columns replace independent cells, and there is no cell-level editing
ChartMogul
Pros
- + MRR movements reconciled exactly month to month in my testing — new, expansion, contraction and churn lines summed to the reported change with no manual corrections on a Stripe setup
- + Free up to $10K MRR with the full metrics model included, which makes it the obvious starting point for pre-$10K-MRR SaaS
- + The per-customer MRR table shows annual normalization, proration and exchange-rate impact as visible lines instead of burying them in a total
- + Segmentation goes deep with custom sources — I built an LTV-by-acquisition-channel report by joining external lead data, which flat metrics tools cannot do
- + REST API, MCP server and CSV access on every plan, so the data is yours to move even at the free tier
Cons
- - Pricing scales with ARR tracked: the analytics bill grows exactly when the business does, reaching the high hundreds per month by $5M ARR
- - Starter allows only one billing system and three team members, so any multi-system revenue setup forces Pro
- - Accounting connections run through a partner (SaaSync) with a manual review queue for invoices the system cannot parse
- - Forecasting is limited to the AI assistant's projections; serious planning needs a warehouse or BI export on Pro and above
- - Third-party review sites still publish outdated plan names and prices — only the vendor pricing page reflects the current Starter/Pro/Enterprise tiers
