- Primary Operational Bottleneck: Firmographic Match Degradation: VPN adoption and remote-work IP sprawl frequently degrade reverse-IP identification accuracy, defaulting enterprise visitors to unsegmented fallback playbooks.
Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Drift requires sales-gated custom quoting).
Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Drift order form before signing a 12-month enterprise commitment.
