Chloe is excited. She just received an email from her go-to fashion retailer about a new line of sustainable activewear — the pieces are precisely her style and in her favourite earthy tones. One item stands out and she quickly places an order. But when it arrives, the fit of the garment is not quite right. She heads to the app, ready to return the garment. The retailer’s virtual assistant greets her by name, acknowledges and apologizes for the issue, and suggests a replacement based on her previous orders. It even senses her frustration, proactively offering a discount on her next order. It doesn’t overstep, but is thoughtful enough to leave her feeling supported, turning the usual hassle of returns into a surprisingly positive experience that leaves her more likely to shop again.
This seamless experience isn’t a mere coincidence; it’s the power of Customer Digital Twins (CDTs) at work. This dynamic, virtual replica of Chloe constantly learns and evolves with her every click and preference, enabling the brand to anticipate and deliver with precision.
Meticulously balancing AI’s immense potential with non-negotiable requirements for customer privacy, transparency, and trust is critical as organizations enable these hyperpersonalized “segment of one” experiences. Based on our work with Fortune 100 retail, beauty and consumer goods leaders, we’ve seen first-hand how customer digital twins can prove beneficial in bridging the gap between innovation and real-world challenges responsibly.
How are customer digital twins different from digital twins?
The growing digital twin ecosystem, comprising product twins, store twins, warehouse twins and network twins, is fast changing the retail and consumer landscape. Customer digital twins are notably the new kid on the block.
Unlike conventional digital twins that model physical assets, CDTs focus exclusively on emulating human behavior. These AI-powered virtual replicas of real-world customers constantly learn from data aggregated through CRM systems, POS terminals, browsing patterns, social media interactions, and IoT devices to create anonymized, dynamic customer avatars. The underlying systems are built on privacy-by-design principles to maintain customer trust with anonymized data, strict access controls and compliance checks aligned with GDPR, CCPA, etc. Using machine learning, the avatars simulate real-world behaviors, enabling retailer and consumer enterprises to:
- Predict reactions to price changes, product launches, or marketing campaigns
- Model individual decision-making processes (e.g., how weather or social trends influence purchases)
- Test strategies at scale without risking customer trust
The GenAI and Agentic value unlock: Integrating GenAI and LLMs into CDTs has helped them evolve further and empowers them to act as autonomous agents. LLMs proactively analyze vast unstructured data, constructing rich, nuanced customer profiles that transcend basic demographics. A multitude of purpose-built CDT agents then personalize experiences, crafting tailored content and iteratively testing these against the virtual avatars it has generated with a human-in-the-loop to refine outcomes. Conversational interfaces become an intuitive and accelerated pathway for marketers to autonomously validate synthetic content against synthetic profiles or avatars, significantly boosting campaign efficiency. CDTs have thus evolved into dynamic, intelligent agents that are complex, layered, and capable of truly emulating real-world customer behavior and driving targeted outcomes.
High-value use cases for customer digital twins in retail and CPG
When responsibly designed and deployed, CDTs unlock a wide range of applications across the retail and consumer landscape. Here are some of high-impact use cases we’ve observed today:
- Product and packaging testing: CDTs allow consumer enterprises to virtually test customer reactions to new product variants, packaging designs and product information.
- Campaign evaluation: Retailers can evaluate social media content and campaign content across channels for customer reactions and simulate engagement outcomes without solely relying on real-world cohorts.
- Dynamic pricing and promotions: By simulating how individual customers react to price changes (e.g., a 10% discount vs. bundling offers), retailers can optimize margins while maintaining loyalty. A leading confectionary giant has partnered with us to explore a variety of customer twins or synthetic avatars to predict customer reactions on price perception.
- Omnichannel experience optimization: CDTs unify data from physical stores (via IoT sensors), e-commerce platforms, and mobile apps to:
- Predict cross-channel browsing patterns (e.g., “webrooming” vs. “showrooming”)
- Arrive at next-best actions based on the simulated virtual customer’s reactions across the lifecycle
- Ethical risk mitigation: Before launching sensitive campaigns, retailers can use CDTs to identify unintended biases in messaging and simulate privacy compliance scenarios (e.g., GDPR data handling).
Architecting Your Customer Digital Twin: The 4 foundational pillars
Harnessing the full potential of customer digital twins requires a strategic approach to technology and data. Drawing from our work in the retail and consumer domain, we’ve broken down the key capabilities needed for converting data into a living, actionable representation of your customer.
Integrated data infrastructure and real-time processing:
- Unified data foundation: Establishing a comprehensive data platform that integrates data from diverse sources (CRM, transactional, social media, behavioral) is a prerequisite to setting up your CDTs. Utilize machine learning to cleanse, standardize, and enrich this data, creating a holistic customer view that ensures the right context is available for CDTs rather than relying entirely on world knowledge of LLMs.
- Real-time data integration and processing: Enable the platform to ingest and process real-time data streams (website interactions, social feeds, support logs) so the CDT receives dynamic updates and can generate accurate simulations.
AI-driven avatar synthesis and behavioral simulation:
- LLM-powered profile synthesis: Use LLMs to generate detailed synthetic profiles from diverse data and behavioral patterns such as purchasing habits, browsing activity and social interactions. Enrich these profiles with realistic demographics, psychographics, and interaction styles to build a robust foundation for deeper customer understanding.
- Iterative refinement of the CDT: Establish AI-driven feedback loops to continuously refine and improve virtual twin accuracy. Leverage ML to analyze real-world customer interactions and adjust CDT parameters so the virtual representations remain relevant and effective.
- Cross-functional simulation platform: Build a scalable simulation platform to use these synthetic avatars across diverse use cases in marketing, sales, product development, support for consistent hypothesis testing and outcome prediction. This also allows teams across the organization to harness the digital twins of customers.
Governance, transparency, and performance measurement:
- Shift left on security, responsible AI, governance and compliance : Design the system with privacy-by-design principles, anonymizing data during synthesis, embedding bias detection in behavior generation, automating compliance checks around GDPR, CCPA and internal policies in feedback loops and enforcing access controls right from platform inception.
- Explainable AI (XAI) and transparency: Implement XAI techniques for insights into how the AI models generate synthetic profiles and simulate behaviors. This enhances transparency and builds trust in the system’s outputs.
- Performance measurement: Establish systems to monitor CDT accuracy (e.g. predicted vs. actual behavior), simulation fidelity (e.g. correlation with real-world outcomes), and business KPIs (e.g., campaign effectiveness, customer lifetime value) for continuous improvement.
Scalable, API-driven, and AI-orchestrated architecture:
- End-to-end scalable and modular architecture: Implement a microservices-based design that allows for flexible adaptation to growing data volumes, diverse use cases, and evolving business needs.
- API-first design: Design the system with an API-first approach, enabling seamless integration with other enterprise systems and applications.
- AI/ML model orchestration: Implement an orchestration layer for managing AI/ML models responsible for synthetic profile generation and refinement. This includes automated model deployment, version control, and performance monitoring, ensuring accurate and up-to-date virtual customer representations.

Through our work with leading retail and CPG brands, we’ve developed a phased roadmap that moves customer digital twins from pilots to scalable solutions:
Phase 1: Pilot low-risk scenarios
- Carve out a minimum viable slice to demonstrate early value
- Start with non-sensitive use cases like social media content testing or product packaging and work alongside business users to garner early acceptance
Phase 2: Build foundational capabilities while refining the prototype
- Refine and stabilize the core generation and simulation capabilities based on the pilot results
- Build your data and AI core by creating a unified real-time customer data foundation
- Evolve the simulation capability to a cross-functional platform and begin implementing robust performance measurement systems
Phase 3: Scale responsibly
- Expand to high-impact areas like pricing or product innovation
- Implement bias audits, embed privacy by design and adopt XAI practices to support transparency (e.g., Why did the CDT predict Customer A would churn?)
What it takes to succeed with customer digital twins
Customer digital twins are fundamentally altering how retail and consumer enterprises comprehend, model, and engage with customers at scale. While early adopters such as Sephora, IKEA, and Walmart showcase the transformative potential of Customer Digital Twins (CDTs), successful implementation transcends mere technological adoption. Brands are obligated to safeguard customer privacy and cultivate trust by integrating robust governance and responsible AI practices from the outset, thereby prioritizing customer interests alongside product innovation.
For businesses exploring CDTs, begin with a pilot that focuses on non-sensitive use cases while building cross-functional teams of data scientists, ethicists and CX experts, and establish robust ethical frameworks from Day 1.
