Key Lessons from These Case Studies
- Clear ownership matters: Successful partnerships had founders owning product decisions and agencies owning execution.
- Domain expertise helps: Agencies with relevant industry experience delivered faster and with fewer mistakes.
- Plan for transition: All companies planned from day one how they'd eventually bring development in-house.
- Founder involvement is crucial: Weekly (or more frequent) founder involvement correlated with success.
- Fixed scope, not fixed everything: Successful MVPs had clear initial scope but flexible approach to features.
Conclusion
These case studies demonstrate that agency partnerships, when structured correctly, can produce successful startup products. The pattern is clear: choose experienced partners, stay deeply involved, and plan for what comes after the MVP.
