WUNDER is an AI service that lets you talk with your Customer Twin
— first-person simulations of how your real customers think and feel.

ABOUT WUNDER

Our vision

We believe the next era of decision-making is conversational.
Our vision is a world where every team can talk directly to the intelligence inside their data — and make better decisions in seconds, not weeks.

What we do

We turn your customer data into a live, conversational Customer Twin so you can ask questions, test ideas, and uncover deeper insights. This delivers action-ready strategies, faster decisions, and lower risk for every launch.

Why we exist

To give every team a new interface for deep customer understanding — a direct, conversational way to explore how customers behave, decide, and respond, without dashboards or complexity.

WUNDER Mission

Bring your customer into the room
— so teams stop talking about customers and start talking with them.

USP – Why we are different.

1) A new interface for customer understanding

A direct, conversational way to explore how customers think and feel — replacing dashboards with a dynamic, talk-to-your-customer experience.

2) The most meaningful customer data

From noise to signal: behavioural patterns, affinities, and emotional indicators combined into a clear portrait of customer intent.

3) A progressive blend of AI technologies

A hybrid system using neuro-symbolic AI, reasoning engines, and proprietary knowledge graphs — including the Emotion Graph — for depth, accuracy, and semantic understanding.

Third-wave AI for Ultimate Customer Centricity

WUNDER uses a progressive AI stack to enable entirely new levels of personalization. Its ‘mind-matching AI relies on data harmonization and reacts to individual customers in real-time.

WUNDER was founded by Rupert Steffner, former Head of Behavioral Insight at Groupon and Otto, a world leading authority on eCommerce AI with three decades at the cutting edge of commercially successful innovation. With a team of AI, cognitive scientists and data engineers, WUNDER has brought innovative software solutions to market that harness the power of marketing AI.
