What is Sunzu?

Shape products people love. Get user insights in minutes. Sunzu is an AI research platform that helps insights, product, design and marketing teams test ideas, designs and ads before committing time and budget. Our AI-powered synthetic humans simulate customer behaviour so teams can explore more questions, compare options and identify likely friction early. Cut research costs. Let every team test and learn. Use Sunzu across four research workflows: • Depth interviews: explore customer needs, motivations, priorities and language. • Concept testing: compare ideas, propositions and product concepts to understand what resonates and why. • Usability testing: identify confusing experiences and potential barriers before release. • Ad testing: explore reactions to messages and creative before committing campaign spend. Our composable AI combines more than 20 layers, including algorithms and specialised models. The platform draws on proprietary data, behavioural modelling and research principles to simulate human responses. Sunzu evaluates its approach through internal research and comparisons with human research. Run studies through the Sunzu web app. Teams can also use supported research workflows from compatible AI assistants through our MCP integration, bringing customer insight into the tools they already use. Use Sunzu to explore directions, challenge assumptions and prioritise questions for deeper human research. From early discovery to pre-launch testing, Sunzu helps teams spend less time waiting for answers and make better-informed decisions about what to build, improve and communicate.
