What did Zeotap announce?

Zeotap launched Open CDP, describing the product as the first fully composable customer data platform. The platform runs on open-source compute and on the customer's own lakehouse. Zeotap framed the launch under a "sovereign by design" positioning, signaling data-residency guarantees built into the architecture.

What does "fully composable" mean here?

A composable CDP replaces the bundled, all-in-one architecture of legacy suites with modular components that practitioners assemble, swap, or scale independently. Zeotap's claim of "fully composable" indicates that core CDP capabilities ship as decoupled services rather than a single monolithic application. Marketing teams keep their existing warehouses, orchestration tools, and activation channels. They do not migrate data into a vendor-controlled environment to use the CDP.

Why run on the customer's lakehouse?

Lakehouse architectures combine the cost profile of object storage with the SQL performance of a warehouse. By running on the customer's own lakehouse, Open CDP removes the step of copying customer data into a proprietary store. The data stays in the practitioner's existing environment. The CDP executes transformation, identity, and audience logic in place.

Three practical consequences follow:

• Reduced egress and storage costs tied to duplicate copies
• Stronger compliance posture for GDPR and emerging data-protection rules
• Direct access to first-party data for analytics teams without an ETL round-trip

What does "sovereign by design" imply?

The "sovereign" label in martech typically signals data residency, processing locality, and contractual guarantees against foreign access. For European brands, sovereign positioning responds to post-Schrems II procurement requirements. A CDP that runs on the customer's own lakehouse reinforces the posture: the vendor's servers do not see the underlying customer records.

Who is the target practitioner?

Open CDP targets three buyer profiles:

• Enterprise data teams already standardized on a lakehouse
• Regulated industries — banking, healthcare, telecoms — that need auditable data flows
• Mid-market brands that want CDP capabilities without committing to a separate data warehouse contract

What remains unconfirmed

The launch announcement covered by Yahoo Finance UK does not enumerate pricing, deployment SLAs, supported identity resolution methods, or integration partners. Practitioners evaluating Open CDP will need:

• A list of compatible lakehouse engines
• Pricing models (consumption-based, seat-based, or flat fee)
• Connector coverage for ad platforms, DSPs, and CRM systems
• Reference deployments and case studies

Zeotap did not publish those details in the announcement covered by Yahoo Finance UK.

Why it matters for the martech stack

The composable CDP category has matured since 2021. The differentiator Zeotap claims is infrastructure-level: rather than asking the customer to bring it data, Zeotap brings the CDP to the data. That inversion reframes the procurement question from "which vendor stores our customer data?" to "which vendor runs identity resolution where our data already lives?"

Marketing, data engineering, and analytics teams will increasingly evaluate vendors on where the compute happens, not just on which features ship in the UI. The Open CDP launch signals that the boundary between warehouse and CDP is dissolving.
