  • Primary Operational Bottleneck: Synthetic Data Drift: Synthetic audience projections can diverge from actual purchase patterns when external consumer sentiment or macro pricing shifts occur rapidly, requiring ongoing baseline calibration against ground-truth conversion telemetry.

Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Kana requires sales-gated custom quoting).

Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Kana order form before signing a 12-month enterprise commitment.
