CDP overview

What is a Customer Data Platform?

A Customer Data Platform (CDP) is a software system built for customer data collection and customer data management. Its purpose is to collect customer data from various sources, unify that data by building a customer 360 with comprehensive customer profiles, and activate these profiles in downstream tools managed by marketing, product, and other organizations within a business.

The CDP adds value across a company by enabling all sorts of use cases like advanced product analytics, personalized marketing campaigns, enriched customer data in sales CRMs, and deeper customer journey analysis to enhance the customer experience from end-to-end. Many CDPs like Segment and RudderStack operate in real-time, offering immediate action and optimization to enhance customer engagement.

What is a CDP used for?

CDPs were built for collecting first-party data (user behavior data, transactional data, etc) using event streams and ETL data pipelines, creating a deduped, 360-degree view of customers with out-of-the-box identity resolution tools, and enabling marketing and product teams to build audiences and segment users based on features they define.

From there, these audiences and segments can be analyzed in product analytics tools like Amplitude or Mixpanel, activated in marketing automation tools, and sent to advertising platforms so that digital marketing teams can ship targeted advertising campaigns, product teams can deliver personalized user experiences, and email marketing teams can send the right emails at the right time to the right users.

In short, we can think of CDPs as API integration platforms that enable businesses to collect, unify, and activate first-party data, improving the ROI of ad campaigns, increasing conversion rates on their marketing websites, and improving efficiency by decreasing customer acquisition costs and reducing churn.

Following the $3.2 billion acquisition by Twillio in 2020, Segment has become one of the most popular CDPs on the market, giving marketers the ability to make customer experiences across every channel more personalized, timely, and impactful. Since then, customer data platforms have proliferated and today, there are several competitors and alternatives to Segment to weigh before deciding on which CDP is right for your business.

Segment overview

How did Segment start?

Believe it or not, Segment (previously started as a classroom lecture tool that CEO Peter Reinhardt and his roommates had the idea to build while studying aerospace engineering and computer science at MIT.

Founded in 2011, the idea was that the tool would allow students to signal to a professor that they were lost or confused during a presentation, then the professor could see a graph that would let them know the overall status of the class’ comprehension and thus if the lecture was missing the mark.

In December 2012, after some funding, a couple pivots, and near failure, the roommates decided to open-source a JavaScript library they had developed that offered a workaround to deal with the frustration the team had finding a single analytics platform that could deliver all the insights they wanted.

The JavaScript library gathered all the data being collected on the Segment website and then funneled it simultaneously to several analytics services. They posted the JavaScript library, dubbed simply “analytics.js”, to GitHub, began pitching it to developers, and shared it to Hacker News. The rest is history–Segment as we know it was born.

What is Segment?

Despite its humble beginnings, Segment has grown into a multi-billion dollar Customer Data Platform (CDP) for marketers that simplifies collecting and using data from the users of a company’s digital properties like marketing websites, mobile apps, web apps, etc. Segment simplifies the process of collecting data and integrating with new tools, allowing marketers to spend more time finding value in customer data, and less time trying to collect it.

Beyond collection, Segment also allows marketing teams to enrich the customer data collected by connecting data from other tools, aggregating it to monitor performance, inform decision-making processes, and create uniquely customized user experiences. You can also use other tools like Unify, Segment’s identity resolution tool, to unify data from individual users to gain a wholistic understanding of their actions.

Who Uses Segment?

Pre-Twilio acquisition, Segment was a tool built for software engineers and developers. Since the acquisition, Segment has focused primarily on the marketing persona. Segment appeals to marketers because it gives them an easy way to collect and merge different data sets to create customer profiles, enrich audiences, and activate campaigns across various tools.

Historically, engineering teams have been drawn to Segment because they don't have to spend time creating their own event tracking library and building custom integrations to all of their downstream SaaS tools.

Using Segment, developers and engineers don't have to build and maintain API integrations and data pipelines, and marketing teams can experiment quickly and launch marketing campaigns without being slowed down by data team requirements.
