Why pay vs DIY or competitors
Rough order-of-magnitude comparison for a 10-participant cohort study.
| approach | monthly cost | what you actually get |
|---|---|---|
| Lacudelph Pro | $99 | Adaptive research moderator, per-session reflection, cross-cohort aggregation, LLM costs included to daily cap. |
| Listen Labs / Userlytics | ~$10K+ enterprise | Recruitment + recordings, but the interview is whatever the moderator scripts. No cross-turn memory inside the conversation. |
| DIY: ChatGPT + Zoom + a doc | $20 + your time | Cheap, but no adaptive conductor across turns, no comparable structure across participants, no aggregation. |
Annual billing (2 months free on Solo + Pro) coming soon — until then everything renews monthly. Self-serve at every tier; enterprise / SSO — read the baseline DPA or get in touch.
