Side-by-side comparison of AI visibility scores, market position, and capabilities
a2z Radiology AI raised $20M in 2025 for its whole-body AI that simultaneously screens for 24+ conditions across CT scans — from incidental cancers to cardiovascular risk — in a single automated read.
a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
Customer success platform with SuccessBLOCs lifecycle playbooks; merged with Catalyst for combined enterprise and mid-market coverage competing with Gainsight and ChurnZero.
Totango is a customer success platform providing account health monitoring, playbook automation, and customer lifecycle management for B2B SaaS companies with subscription revenue — helping customer success managers prioritize their accounts, identify churn risk, and trigger automated interventions to improve net revenue retention. Founded in 2010 and headquartered in San Mateo, California, Totango raised approximately $90 million and serves enterprise SaaS companies who need to manage hundreds or thousands of customer accounts with dedicated customer success teams.\n\nTotango's SuccessBLOCs framework packages pre-built customer success playbooks for specific lifecycle stages (onboarding, adoption, renewal, expansion) that teams can activate and customize rather than building from scratch. The platform aggregates data from CRM, product analytics, support systems, and marketing automation to calculate each account's health score. Automatic alerts and tasks trigger when accounts show risk signals (low product usage, increased support tickets, upcoming renewal without engagement), enabling CSMs to intervene proactively.\n\nIn 2025, Totango merged with Catalyst in 2023 to create a combined customer success platform with complementary market positions — Totango stronger in enterprise, Catalyst stronger in mid-market. The combined company competes with Gainsight (the category leader), ChurnZero (mid-market), and Vitally for customer success management platform share. The merger reflects broader consolidation in the CS platform market as the category matures. Totango's 2025 strategy focuses on completing the Catalyst integration to offer a unified platform, expanding AI capabilities for predictive risk scoring, and growing enterprise adoption through deeper Salesforce and data warehouse integrations.
