In this episode of Evolve, Alex Sion, Head of Financial Services at Blend, is joined by Brett King, futurist, author, and fintech pioneer, and Jesse Fagan, Head of Data Science for Blend Synthetic Studios, for a conversation on the growing role of simulation in business. Together, they trace the evolution of simulation from aviation and gaming to AI, digital twins, and enterprise decision-making.
The discussion explores how large language models and synthetic personas are making it possible to simulate human preferences and behaviors with a new level of detail. Jesse shares how Blend is using dense personas, multimodal inputs, and agentic workflows to simulate customer decision points, run synthetic focus groups, and generate actionable insights for clients. Brett connects those capabilities to broader shifts in product design, creative development, and the future of financial services.
The episode also includes a live demo showing how simulation can be used to test product positioning and audience response before going to market. The broader message is clear: as AI makes simulation faster, cheaper, and more scalable, companies will need to treat it as a core part of product development, marketing, and customer strategy, not just an experimental tool.
