You do. The custom development page states that you get software designed for your business, with full ownership and control.
Exclusivity
Unless you agree otherwise, a custom solution is not resold to other clients. What is built for you stays yours.
What ownership means in practice
- The software is built around your requirements, not a generic roadmap.
- You decide where it runs: your own servers, a cloud provider or a mix.
- Your own developers can work on it, or AdTech Europe can keep maintaining it.
Support after handover
Delivery includes handover with ongoing support: post-launch support, maintenance and updates are available. For a predictable monthly arrangement, Support & Maintenance plans start at $390 a month, and the team can maintain custom features it built or review ones your team built.
Custom build vs buying the source code
| Custom build | Platform source code | |
|---|---|---|
| Starting point | Your requirements | The existing DSP, SSP, ADX or DMP |
| Price | Budgets from $15,000, by proposal | $50,000 (DSP/SSP/ADX), $30,000 (DMP) |
| Ownership | Full ownership and control | Complete source code, architecture and documentation |
Many buyers combine both: own the source code of a platform, then commission custom features on top.
