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
Aidoc
Pros
- + Widest FDA-cleared acute triage portfolio I have reviewed: 31 authorisations on the FDA's December 2025 list, plus the first multi-indication clearance covering 14 abdominal CT findings in one workflow
- + Multi-triage consolidation meaningfully reduces alert noise — one flagged study produces one stacked panel, not one pop-up per algorithm
- + Real-world deployment evidence: Mercy Health documented urgent case turnaround falling from 19.8h to 1.3h across 50+ hospitals, with 5,642 patients expedited from 50,749 flagged findings
- + Vendor-neutral aiOS layer lets a health system run third-party and Aidoc algorithms through one governance and notification stack (17 FDA-cleared algorithms deployed at Hartford HealthCare)
- + Care Coordination and Patient Management close the loop beyond triage: mobile alerts with image context, and report mining that routes incidental findings to facility-defined follow-up protocols
Cons
- - No public pricing, no trial, no free tier — third-party estimates of ~$50k/site/year baseline with $8k-$15k per extra module are unverifiable until you are deep in a sales process
- - Hospital-only: requires PACS/RIS/EHR integration work, so it is irrelevant to individual clinicians, small practices and low-volume facilities
- - 510(k) clearance for most modules does not itself require independent clinical performance data (per JAMA Network Open) — buyers should demand the study set, not just the clearance count
- - No public changelog for algorithm updates, which is a real gap for a system whose output feeds clinical decisions
- - Vendor performance figures (order-of-magnitude false-alert reduction, 1,600+ hospitals) are company claims I could not independently audit
