Sunzu is an AI user research platform that gives product, design, marketing and insights teams user insights in minutes. Its AI-powered synthetic humans simulate human behaviour, helping teams test ideas, designs and ads before committing development time or campaign budgets. Research should help shape a decision while there is still time to change it. Sunzu helps teams cut research costs, explore more options and identify likely friction before launch. It expands access to customer insight across the company, so more teams can test and learn as part of their everyday work. Sunzu supports four research workflows: - Depth interviews: Explore customer needs, motivations, objections and the language your audience uses. - Concept testing: Compare ideas, features and propositions before deciding what to build. - Usability testing: Identify confusing steps and likely friction in designs, prototypes and user journeys. - Ad testing: Explore audience reactions to messages and creative before committing media spend. Sunzu’s composable AI combines 20+ layers, including algorithms and small models. Research is grounded in customer evidence, such as interviews, surveys, support themes and product analytics, and enriched with a behavioural corpus. Findings include source references, confidence ratings and evidence gaps to support review. Teams can run all four workflows in the Sunzu web app. Depth interviews, concept tests and usability tests are also available through compatible AI assistants, including Claude and ChatGPT, via MCP. Sunzu reports testing 500× faster than human research, based on its own proprietary research. Its simulations help teams explore directions and focus follow-up research with real people. Cut research costs. Let every team test and learn. Shape products people love.
