Both give you a platform you control. The right choice depends on how different your business is from a standard DSP, SSP, ADX or DMP.
License or own an existing platform when
- A standard DSP, SSP, ADX or DMP covers most of what you need.
- You want to start quickly: a licence is a fixed price (for example $25,000 for the DSP, SSP or ADX, or 12 × $2,500).
- You want the full source code of a proven platform ($50,000 for the DSP, SSP or ADX).
- Any gaps can be filled with plugins or a few custom features.
Build custom when
- Your model does not fit a standard platform, for example unusual traffic routing or a niche ad server.
- You need a platform designed around your own workflows from the start.
- Budgets start at $15,000, depending on scope.
A middle path
Many clients license or own a platform and then add custom features. The team builds new platforms and also adds features to existing ones.
