When do you need your CDP?
A need for speed will dictate whether you choose to buy or build certain components. If you need your CDP up and running quickly, SaaS is the best option. Most software can be deployed and quickly integrated without the need for additional technology resources.
Custom-built CDPs on the cloud can take months to develop. And like many “construction” projects, you may miss your deadlines. It should be no surprise that the larger the custom proportions in the project, the longer it takes.
Often, a CDP has to be constructed from existing systems and must be running to collect data from campaigns those systems are already serving. If there is an event coming up that will represent a large data capture opportunity, you should probably go with something plug and play. You can always hybridize or start to build components as you go, and the right SaaS vendor will discount their product for purposes of a proof of concept.
