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. Product, Engineering, 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.
- 04Adoption level 3 of 5. Level 1 is one tool and no workflow change. Level 5 is an agent running the work with a human auditing it.
- 05Pricing model on record: Free tier + Pro at $39/mo.. 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.
