AI takeaways
Keep the key points here, or take a source-aware text brief into Claude, ChatGPT or another AI workspace.- 01Define which platform produces more usable, permitted and governable prospect records for the buyer's actual regional ICP before comparing products.
- 02Keep authoritative records and policy outside the presentation layer.
- 03Require buyer-run failure, recovery and correction evidence.
- 04Use explicit denominators and keep vendor outcomes quarantined.
Run a matched-country bake-off, keep counts beside rates, and let reachability, permission operations, workflow fit and contract exit—not reputation—decide.
