## Warned against

- Watershed: 7 of 42 labels negative. "may be well suited to emissions accounting, but can be insufficient for broad social, governance, controls, and financial-reporting workflows" (Perplexity Sonar, negative prompt)
- Persefoni: 6 of 33 labels negative. "Avoid these unless user access is tightly restricted to a small core team." (Grok 4.20, budget prompt)
- IBM Envizi: 6 of 50 labels negative. "Some important features are not included in all subscription plans, it's expensive for medium and small-scale organizations, and some customers feel the product does not always deliver on its promises." (Claude Haiku 4.5, negative prompt)
