Abstract

Early-stage product teams often require user insight before real customer data, survey panels, or interview participants are available. This creates a decision gap between product ideation and validated user understanding. Traditional research methods such as interviews, surveys, focus groups, and market studies remain essential, but they may be slow, expensive, or unavailable during concept exploration. This paper presents a persona-driven AI survey engine for synthetic user modeling and decision simulation. The proposed system combines large-scale synthetic persona data, heuristic audience filtering, behavioral segmentation, large language model-assisted persona construction, persona-aware survey generation, simulated response generation, and structured insight extraction. The framework is demonstrated through the FlexiSave Kids Plan, a hypothetical financial product for parents of children aged 4–10. Implementation artifacts are provided through a public GitHub repository, including a notebook workflow and JSON artifact structure. The results show how synthetic personas can surface segment-specific needs, objections, trust concerns, and feature priorities before real-world validation. The paper argues that synthetic personas should be used as decision accelerators, not empirical substitutes for real users.
