Solstice Travel: Users Sign Up and Disappear
Product Management
medium45 min0 submissionsGoogle
Scenario
Solstice Travel's online travel product acquires users steadily but struggles to keep them.
Retention curve (all users):
| Day | Retained |
|---|---|
| D1 | 49% |
| D7 | 34% |
| D30 | 11% |
| D90 | 9% |
What else we know:
- 33% of new users complete the core action at least once in week one
- Among users who complete the core action three or more times in week one, D30 retention is 33%
- 13% of users account for roughly 75% of total usage
- Exit surveys most commonly say "didn't find it useful" and "forgot about it"
Growth is currently offsetting churn with paid acquisition, at a blended CAC that has risen 49% year on year.

- Risks — of the interventions you propose.
- Recommendation — what you would build, and how you would measure success.

Hint
Reveal suggested structure
- Read the curve's shape. A steep D1→D7 fall is an onboarding or value-discovery problem. A curve that never flattens is a product-market fit problem. These need opposite responses.
- Find the habit moment — the behaviour that separates retained from churned users.
- Compare segments — the 3×-core-action cohort is the natural experiment already in the data.
- Attack the biggest drop-off first.
- Instrument the intervention so the effect is measurable.
