## Warned against

- IBM Apptio Cloudability: 23 of 27 labels negative. "Enterprise-grade tools (like IBM Cloudability or Broadcom’s CloudHealth) are generally overkill and too expensive for smaller scales." (Gemini 3.5 Flash, budget prompt)
- VMware Tanzu CloudHealth: 21 of 23 labels negative. "Why to Avoid: They typically require custom sales negotiations, professional services setups, and can cost significantly more per month than your actual cloud bill." (Qwen 3.7 Flash, negative prompt)
- Flexera One: 11 of 14 labels negative. "prohibitive upfront costs for SMBs, implementation complexity, and UI navigation issues. Better for large multi-cloud enterprises." (Grok 4.1 Fast, negative prompt)
- CloudZero: 8 of 36 labels negative. "Enterprise-focused platforms (e.g., Cloudaware, CloudZero, some offerings from Flexera) are often too expensive or complex for small businesses" (Mistral Small, negative prompt)
