## What the models said about Persefoni

- "Enterprise-grade platforms (like *Workiva*, *IBM Envizi*, or *Persefoni*) are usually overkill" (Gemini 3.5 Flash, scale prompt, soft negative)

- "| Workiva | $50K–$150K+ (likely overkill) | Skip unless you need integrated financial + ESG reporting |" (DeepSeek V4 Flash, scale prompt, hard negative)
- "Platforms like Workiva excel here because they allow you to import messy Excel sheets, clean the data within the software using "source codes," and publish to a final PDF, keeping an audit trail." (Qwen 3.7 Flash, scale prompt, first choice)
- "If you're a mid-market B2B company and want one default pick:

- Choose Workiva if ESG reporting is tightly connected to finance, board reporting, or audit/compliance." (GPT-5.4 mini, direct prompt, first choice)
- "Choose Workiva if: You need to produce high-stakes regulatory filings (SEC/CSRD) and need rigorous control over who sees and edits data." (Qwen 3.7 Flash, comparative prompt, first choice)
