Marketing teams: You don't need a CDP. The future is the data warehouse.

Marketing teams, desperate to access a single unified profile of the customer, are rushing out to buy Customer Data Platforms (CDPs).
Five years ago, CDPs seemed like the right answer to the problem, and more than a billion dollars has been invested in CDP companies since then. But times have changed. Technology has evolved. The problem is no longer data collection (in fact, we’re drowning in more data than ever). Rather, it’s shifted to: How do we actually access and activate that data? 🤔
What we can learn from those who did buy CDPs, is that CDPs have not delivered on their promises. Instead, data-forward companies are switching to an alternative solution that costs far less and delivers value much faster: Activating their data warehouse.
A Customer Data Platform (CDP) is an all-in-one platform built for marketing teams that:
Well, that was the dream anyway; the reality is no true all-in-one solution exists. Even inside the CDP category, many are focused on different areas. For example, Twilio Segment is stronger on tag management, whereas Amperity is more of a vertical solution providing more analytics for retail.
Nowadays, every marketing tool is claiming to be a CDP. Sure, they are storing increasing amounts of customer data, but they don’t have the full picture of the customer because marketing automation and support systems are still disconnected and have limited activation capabilities. 🚫
The number one reason why marketing teams are rushing out to buy CDPs is to get a unified view of their customer, with 63% of marketers saying that unifying data is their key challenge. They know that building a unified view of the customer will enable them to run better campaigns with richer data to drive more ROI. And they believe that an off-the-shelf solution will enable them to do this faster (and without being dependent on data and IT teams).
But these promises haven’t come to fruition.
CDPs promised us some amazing things 👇
Like most promises that sound too good to be true – it was. 😔 Fast-forward about 5 years since CDPs came on the scene, and only 1% of companies are actually meeting their current and future needs with CDPs (Forrester 2022).
So, what can we learn? And why haven’t CDPs lived up to their promises? Let’s bust some CDP myths. 👊
CDPs claim to be the single source of truth for customer data, but they do not (and cannot) replace data warehouses. Why? Simply because CDPs don’t have all the customer and company-level information to be a complete source of truth for analytics. ⭐Instead, data collected by CDPs is copied to the data warehouse to power trusted analytics, instantly diluting the CDPs' promise of a “single source of truth.” Whilst some CDPs are now supporting importing data from the data warehouse, doing so results in additional data latency and still doesn’t solve the fact that the CDP is still just another silo of data. Due to this fragmentation, data inside the CDP is not as trusted or fresh as in the data warehouse.
CDPs are a black box when it comes to how they transform and unify customer data. ⬛ And it’s not possible to generate a unified view of your customer without encapsulating the custom entities, relationships, and business objects that are unique to your business.
For example, Segment Personas has only two core business entities: Users and accounts. But in reality, modern companies have many of their own unique entities and hierarchies that don't fit into the standard "users" and "accounts" categories. For instance:
CDPs have event-driven architectures, and importing custom data on your user often requires data to come in via an event structure. Unfortunately, this doesn’t always make sense when you’re dealing with aggregate analytics and makes it difficult to change historical data (e.g. if a user changes their team membership).
CDPs promised fast ROI and self-service data, but the reality is very different. In addition to their expensive price tag, CDPs require a significant initial investment of engineering time and resources to set up. 🫰 When buying a legacy CDP, you're also forced to evaluate everything upfront because you're locked into a single platform. With months before you realize any value from activation and over 75% of CDP projects currently running over schedule, you're posing a huge risk to your investment. 😬
Many companies also underestimate the ongoing engineering resources needed to maintain a CDP. CDPs provide overlapping functionality to many of the data and engineering tools within the organization, meaning that engineering teams need to integrate CDP-specific data workflows into existing tools or add additional staff dedicated to managing the CDP.
The goals of a CDP are still very relevant today – but are all-in-one CDPs the right solution?
CDPs emerged when marketing teams needed a way to collect their customer data, build unified customer profiles, and activate that data across different marketing channels. They attempted to solve this problem by having their own database for data collection, but in the process, they just created another silo of data.
Since then, other data technologies like data warehouses have advanced in scale and sophistication, while simultaneously getting significantly cheaper. Most growing companies are already investing heavily in data warehouses to power analytics and reporting, so is it still necessary to buy a CDP?
Let’s break it down. Companies typically buy CDPs for data collection, transformation, and activation.
So the collection and transformation pieces are already happening inside your organization – and the data warehouse has emerged as the most complete single source of truth for customer data. Today, however, the most common destination for this single source of truth is a dashboard. But dashboards are where data goes to die, because actually activating those insights still requires complex pipelines and engineering effort.
This is where warehouse-native data activation comes in. 🦸

Data activation is the missing piece needed to connect the data collection and transformation efforts of the data team and make that data accessible to marketing teams to activate across all their channels. Warehouse-native data activation tools like Census enable marketers to unlock data directly from the warehouse – all without needing to know SQL. These warehouse-native activation tools enable marketers to 👇
This alternative approach to a CDP is known by a few names: Composable CDP, unbundled CDP, headless CDP, etc. Although the name might differ depending on who you’re talking to, they are all ultimately saying the same thing: Use your data warehouse as the source of truth for customer data, and activate data where it already lives.
Warehouse-native data activation tools bridge the gap between marketing teams and data teams. 🌉 They allow data teams to define a set of trusted underlying tables or business entities that marketing teams can then use to sync customer attributes, or combine to build dynamic segments of users. In fact, tools like Census fundamentally change the way data and marketing teams collaborate to make marketing teams more agile.
A true single source of truth for customer data
While legacy CDPs on the market only give you a partial copy of your customer data, Census integrates with your data warehouse to provide you with a complete view of ALL your customer data. With this 360-degree view, organizations can easily leverage data from all sources, including POS systems, data science models, and even offline data to get a comprehensive understanding of their customers.
Faster Time-to-Value
CDPs are expensive. Like really, really expensive. 💰 This cost might be justified since it’s an all-in-one solution, but if you’re dropping a big chunk of change on a CDP, you need to be able to justify the value. And when you buy a legacy CDP, you have to think about everything before making your purchase because once you're locked into the platform, it’s game over. 🔒
On top of a long and difficult onboarding process, you won't be able to run any campaigns for months. However, with Census, organizations can connect to their warehouses and activate existing customer data so they can launch campaigns in minutes (literally) instead of waiting months.
More control and flexibility
CDPs that follow a legacy model limit customer data to a rigid structure. This might appear efficient at first, but businesses come in all shapes and sizes, meaning they require much more flexibility than what these CDPs can offer.
Data warehouses, on the other hand, have the ability to store and query relational data of any kind, making them ideal for organizations with complex needs. For example, data warehouses can represent relationships between users and entities like accounts, teams, workspaces, or devices. So, when it comes down to it, data warehouses provide organizations with the infinite flexibility needed to support even their most complicated use cases.
Every company should invest in a customer data platform. That’s not even a question. The real question is two-fold: Do you invest crazy amounts of money into an all-in-one solution? Or do you go for a more flexible approach that delivers value today, using warehouse-native data activation to create your own composable CDP?
Regardless of what you choose, there’s no denying that when it comes to the future of the CDP, the tailwinds are heading in the direction of the data warehouse. ✈️ CDP vendors like Twilio Segment and mParticle have recognized this by recently announcing their own versions of “reverse ETL connectors”, meaning that even they are acknowledging that the current CDP is incomplete. Customers need to enrich and activate data from the warehouse, and these now “legacy” CDP platforms were not designed natively for the data warehouse. Any attempt to “slap on” reverse ETL will be an afterthought.
The rise of the data warehouse as the single source of truth paired with warehouse-activation tools like Census takes away the need for organizations to invest in expensive all-in-one CDP solutions that don’t provide time-to-value. With data activation and reverse ETL democratizing access, the data warehouse is best positioned to become the system of customer record that powers not just your marketing technology, but the entire business operations of the company.
