01How do you decide between an agency and an in-house team?
Nobody needs an opinion on agencies versus in-house. You need to know what's slowing your testing down. If it's context about your brand, hire inside. If it's capacity or specialist skills, an agency gets you there faster.
| Model | Strength | Risk |
|---|---|---|
| In-house | Knows your company and owns the program long term | Slow to ramp up, few specialists |
| Agency | A working system and a specialist team from week one | Needs close alignment with your priorities |
| Hybrid | Ownership inside, speed from outside | Needs clear roles and clear decision rights |

02When should you hire an agency?
Hiring a CRO manager, a designer, a developer and an analyst takes months. An agency brings all four on day one. That matters most when your tests aren't shipping, when nobody trusts the numbers, or when your team simply has no room left.
03When should you build in-house?
- Testing is part of your strategy for good, not a project.
- You have enough traffic and enough tests to keep dedicated people busy.
- Engineering, analytics and design have time to support the program.
- Someone senior makes decisions on results quickly.
If you can't tick all four yet, an agency is usually the faster way to a program that works. You can still bring it inside later.
04What does a hybrid setup look like?
The hybrid model works well once a shop grows. Your internal owner knows the brand, the roadmap and the politics. The agency brings the specialists and the volume. What makes it work is clear roles: who picks the tests, who approves them, and who calls the result.
05Where does DRIP fit?
We run Prediction-Based Experimentation. Before an idea gets built, Apex by DRIP, the testing tool inside DRIP, gives it a Likelihood to Win, based on 4.3 million A/B tests from 151,000 shops. That's a database no in-house team can build on its own. We've also run 4,000+ experiments ourselves, and more than 50% of our A/B tests win.
If you want to see how the work splits between your team and ours, here's our process.
