Stellantis picks Amperity to unify customer data across its brands

Stellantis has selected Amperity, the Seattle-based customer data platform provider, for a company-wide customer data transformation programme intended to identify customers consistently across its portfolio of brands and touchpoints. The deal, announced 13 November 2026, targets one of the hardest identity problems in consumer industries: recognising the same buyer who appears in dealer records, service-centre logs, websites, apps and financing systems over years of vehicle ownership.

The stakes are concrete. Stellantis owns a portfolio of marques across several markets, and a single household may own more than one vehicle or buy from different brands within the same group. Each interaction — a service visit, an online configuration session, a financing application — can generate a separate customer record. Amperity's software combines records from different systems into a single customer profile, and more than 400 brands worldwide already use the platform across retail, travel, financial services and hospitality.

What did the proof of concept show?

Amperity said it ingested millions of Stellantis records in minutes and produced a unified customer view from Stellantis automotive data in less than three days. The company described the exercise as designed to reflect real-world requirements and to support complex, real-time uses across the customer journey.

Stellantis chose Amperity after assessing the platform against its business requirements and against live automotive data, not synthetic test sets. That detail matters for enterprise software procurement, where proof-of-concept results on realistic data volumes often determine whether a pilot becomes a deployment.

Amperity also said Stellantis can connect its existing data and technology systems through the platform's architecture. The stated goal is to reduce data silos and extract more value from current technology investments rather than force a rip-and-replace programme.

Why does customer identity matter for carmakers?

Automotive groups manage long, fragmented customer relationships. Interactions spread across dealers, service centres, websites, apps and multiple vehicles over several years. The complexity increases when households own more than one vehicle or purchase from different brands within the same manufacturer group.

The problem is structural. Customer information in automotive is typically distributed across retail networks, after-sales systems and digital properties, which makes it harder to recognise when the same person appears in different places. A family may interact with several marques within one corporate group over time while generating separate records through financing, servicing and online research.

Kabir Shahani, Founder and Co-CEO of Amperity, said the automotive sector presents a particularly difficult identity problem because customer records are often split across many systems and interactions.

"Automotive buyers span brands, vehicles, households, dealers, digital interactions and years of ownership, making knowing everything about your customer especially critical," Shahani said.

"We are thrilled to see Stellantis using our unique technology to build the foundation to recognize customers as their needs evolve, and respond in the moments that matter. Amperity's core technology will turn fragmented signals into real-time understanding its teams and AI agents need to make better decisions and deliver more relevant experiences," Shahani said.

What will Stellantis use the platform for?

The platform will make customer information available across the organisation so business teams can:

• build audiences from unified customer profiles;
• respond to real-time signals across the customer journey;
• support cross-brand engagement across Stellantis marques;
• run after-sales activity such as service and maintenance outreach;
• operate loyalty programmes;
• deliver personalised messaging;
• measure campaigns against a consistent customer identity.

For Stellantis, the immediate use case is not limited to marketing. Access to broader customer context can support decisions across engagement, service and measurement, which suggests a wider operational role for unified customer data across the business. Amperity's comments indicate Stellantis is seeking a consistent customer identity layer that can be shared across teams rather than maintained in isolated systems.

Why now? The first-party data shift in automotive

The deal highlights the growing focus among carmakers on first-party data as they seek a fuller picture of customers over longer ownership cycles. Manufacturers are under pressure to coordinate sales, servicing, loyalty and digital communications more closely as consumers move between channels and brands.

Two forces drive this. First, ownership cycles in automotive run for years, not minutes, so the value of a correctly identified customer compounds over every service visit, trade-in and repeat purchase. Second, the same buyer rarely stays within one channel: research happens online, purchase happens through dealers, servicing happens at service centres, and financing generates its own data trail. A manufacturer that cannot connect those threads cannot personalise, cannot measure campaigns accurately and cannot run cross-brand programmes effectively.

The agreement also reflects how automotive groups are trying to connect dealer-led and manufacturer-led interactions more effectively. Dealer networks operate with their own systems; manufacturer digital properties operate with others. Bridging them is as much an organisational challenge as a technical one, and Amperity said the project would help Stellantis recognise customers across brands, households and vehicles.

What does this say about the wider market?

For Amperity, landing a multinational automotive group extends its footprint beyond its established retail, travel, financial services and hospitality base. Automotive identity resolution — matching a buyer across brands, vehicles, households, dealers and years of ownership — is a harder test than single-brand retail, and the claimed proof-of-concept numbers, millions of records ingested in minutes and a unified view in under three days, position the company for similar enterprise deals in other long-cycle industries.

For the customer data platform market, the Stellantis agreement signals that demand has shifted from marketing-led use cases toward operational identity infrastructure. Shahani's reference to "AI agents" needing real-time understanding points at the next stage: unified customer profiles as the data foundation on which automated decision systems act. If AI agents are to deliver relevant experiences, they first need a consistent answer to the question of who the customer is — across every brand, dealership, vehicle and touchpoint a group operates.

For Stellantis, the near-term test is whether the identity layer built on Amperity holds up across live dealer, service and digital systems at production scale, and whether teams beyond marketing actually use it.
