What has to be true before you buy
- 01The friction is genuinely at operations and data. Buying at the wrong stage moves the bottleneck, it does not remove it.
- 02Ownership varies by company. Engineering, Product, Revenue Operations or Operations can own this. Whoever it is owns the outcome, not just the licence. Unowned tools are adopted for a quarter and then quietly turned off.
- 03A human still signs off on the output. Write down who that is and what they are allowed to reject before rollout.
- 04L3 Integrated on the six-level AI Maturity Ladder. AI is wired into the systems of record, not a separate window. This is the effort required for the workflow, not a product quality score.
- 05Pricing model on record: Open Source + Enterprise Cloud pricing.. Confirm the billable unit and what happens when volume doubles.
- 06We found no published case study for this tool, which does not prove none exists. Treat every number on the vendor site as a claim until you run your own baseline.
