## Warned against

- 11x: 17 of 47 labels negative. "Specific vendors that appear in the results as cautionary examples include 11x.ai, which is described as an autonomous-agent category example tied to reported issues like high churn, fabricated claims" (Perplexity Sonar, negative prompt)
- Artisan: 14 of 37 labels negative. "Companies that deployed tools like Artisan and 11x.ai as full SDR replacements have largely reverted to hybrid models or returned to human-first approaches" (Claude Haiku 4.5, negative prompt)
- Regie.ai: 7 of 22 labels negative. "as a standalone enterprise AI SDR agent, it underdelivers on its positioning" (DeepSeek V4 Flash, negative prompt)
- Apollo.io: 6 of 14 labels negative. "Avoid per-seat tools like Apollo or Salesloft if your priority is cost predictability" (Perplexity Sonar, budget prompt)
