- Adoption curve: training required to correctly set BANT/MEDDIC criteria and understand the rules for triggering AI sequences.

❌ Disadvantages
- Initial complexity: setting up sector-specific AI agents and defining the KPI requires an in-depth audit (2-3 weeks) before launching the campaigns.
- Pure ABM orientation: if your need is for large-scale "cold" prospecting (several thousand contacts), Topo.io can be over-dimensioned; it excels in targeting strategic accounts rather than volume generation.
