Ownership. Ownership varies by company. Engineering, Product, Revenue Operations or Operations can own this. Pick one accountable owner before you buy, because a shared owner means no owner.
Challenger. Newer or AI-native entrant competing for budget against the platform you already own. Expect to justify it as net new spend and to prove it against the incumbent's bundled feature.

What has to be true before you buy
- 01The friction is genuinely at demand generation. 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.
- 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 + $39/mo Professional (now part of SmartBear). 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.
