## Warned against

- Informatica MDM: 23 of 53 labels negative. "Examples: SAP Master Data Governance, IBM MDM, Informatica IDMC / MDM, and sometimes Boomi as an MDM-capable platform. These can be strong for large organizations, but reviews and analyst commentary often point to complexity, implementation effort, and services-heavy deployments as real risks." (GPT-5.4 mini, negative prompt)
- SAP Master Data Governance: 13 of 31 labels negative. "Avoid or be cautious with IBM InfoSphere MDM and SAP MDG if your organization is not prepared for their complexity and cost." (Mistral Small, negative prompt)
- IBM InfoSphere: 13 of 19 labels negative. "steer clear of massive enterprise legacy platforms (like SAP MDG, IBM InfoSphere, or Stibo Systems)" (Gemini 3.5 Flash, paraphrase prompt)
- Reltio Connected Data Platform: 8 of 41 labels negative. "Avoid enterprise tools like Reltio/Ataccama unless budget allows" (Grok 4.20, budget prompt)
