In this article, I’ll walk you through what really matters when choosing a Customer Data Platform — the kind of things that make or break success in real-world projects. No theory — just hands-on insights from working with ecommerce, gaming, and B2C companies to build data infrastructures that drive growth without adding complexity.
Most CDP projects that go wrong start with the wrong question: “Which CDP is best?”
The right question is: “What are we trying to achieve with this?”
Are you trying to reduce time-to-campaign? Make experimentation easier? Unify fragmented data for better decision-making? The right platform depends on the problem you're solving. And that varies wildly depending on your size, stack, and growth phase.
In several cases, we’ve skipped the CDP entirely and solved the need with a good analytics layer plus some smart automation. In others, a powerful CDP became the backbone of cross-channel orchestration. The point is: don’t assume you need what others needed. Understand your real use case first.
A CDP should make your life easier, not harder. That starts with how it connects to your stack.
Yes, most CDPs list the same integrations. But the quality of those integrations varies. A lot. Some are just basic connectors that pass raw data with no structure or reliability. Others offer deep logic, identity resolution, and native support for advanced use cases.
I always evaluate two things:
How solid are the native integrations with your most critical tools?
How flexible is the system when you need to go beyond those integrations?
If your stack includes less-common platforms or internal tools, you’ll want an SDK and API you can actually work with. Bonus points for supporting cloud destinations, server-side integrations, and reverse ETL.
This is a common trap. A team picks a CDP that solves their current use case. But six months later, they need new event types, new destinations, or new channels and it all breaks.
Good CDPs are extensible. They let you evolve your data model without rewriting your implementation. They support first-party strategies, handle GDPR changes gracefully, and let you add complexity when you are ready, not when the vendor decides.
When I help companies select or re-evaluate CDPs, I spend time reviewing:
Whether the documentation is actually usable
How active the SDKs and APIs are
Whether support can unblock you quickly (or if you’ll be stuck opening tickets for everything)
One of the biggest signs of a successful CDP implementation? Your CRM or marketing team stops pinging devs every week.
If only technical teams can use your CDP, you're wasting potential. The best platforms let non-technical users build audiences, filter events, and trigger actions while giving technical users the control and transparency they need.
In one project, the CRM team was able to launch new onboarding flows, test variations, and optimize campaigns, all without a single ticket to the dev team. That unlocked speed and creativity.
Collecting data is table stakes. Acting on it is what drives results.
You want to know:
How quickly an event from your app or site becomes usable in a campaign
How fast segments recalculate when behavior changes
Whether automations run in real time or hourly batches
I’ve seen massive wins just by reducing latency. In one case, we went from over an hour to just seconds between user behavior (Amplitude) and campaign trigger (Braze). That alone boosted post-signup conversion significantly.
Real-time might not be necessary for everything. But when it matters, it matters a lot.
Some CDPs look cheap — until your user base or event volume grows.
Always model how costs evolve. Do they charge per event? Per MTU? Per destination? Some also charge extra for identity resolution, historical syncing, or additional environments.
My rule of thumb: keep a copy of your data in a warehouse like BigQuery or Snowflake, and use the CDP mainly for activation. This gives you independence, better control, and lowers the risk of vendor lock-in.
And don’t underestimate the cost of internal time — especially if implementation drags on or the UI frustrates your team.
Not all CDPs are built the same. You’ll find three main types:
Segment-style CDPs (like Segment, mParticle): Combine tracking, ETL, and lightweight CDP capabilities. Good if you want control over event pipelines.
Warehouse-native CDPs (like RudderStack): Let you own your data and build on top of your cloud stack.
Reverse ETL setups (like Hightouch): Skip the CDP and activate directly from your data warehouse.
Each has pros and cons. A Shopify store might do fine with Klaviyo and some tagging logic. A multi-app gaming company? That needs proper orchestration and governance.
Choose the architecture that fits your complexity.
In one project, we unified events from an e-commerce platform, mobile app, and support system into a single CDP. We cleaned and mapped the data, built real-time audiences, and launched targeted automations across Braze and Klaviyo.
+15% post-onboarding conversion
Clear ownership for marketing and product teams
Ability to test hypotheses in days, not quarters
But the biggest win? The organization started thinking more like a system. Less guessing, more learning. Less delay, more action.
Choosing a CDP isn’t about checking boxes. It’s about building a foundation for experimentation, speed, and insight — without burning your team out or locking yourself into a rigid system.
If you're picking your first CDP, or feel like you're not getting full value from the one you have, I can help. Sometimes a few sharp adjustments unlock a whole new level of effectiveness.
Let’s make your data work harder — not your team.
