Hyper-Personalized Behavioral Design: Interview With Lirio’s CEO Marten Den Haring

5 min readDec 11, 2025
Marten den Haring, CEO of Lirio

Of all the companies claiming to achieve hyper-personalization through behavioral science and artificial intelligence, Lirio seems to be the one actually doing it. Marten den Haring, now CEO, joined Lirio as Chief Product Officer in 2019, and has spent the past 5 years building and launching the platform and its personalization engine to drive meaningful behavior change in healthcare. And with Amy Bucher at the helm as Lirio’s Chief Behavioral Officer, you can be confident that the rigor of the science is as solid as it gets.

Lirio’s platform is built on the metaphor of the Large Language Model (LLM), but rather than ingesting semantic data and predicting the next word in a sequence like generative AI models, its Large Behavior Model (LBM) draws on health behavior data to predict the next behavior in a sequence of behaviors for an individual. The result is a hyper-personalized behavioral model that provides recommendations optimized for each user.

In this interview, Marten den Haring shares how he combines behavioral science and AI to design for health behavior change, and specifically how Lirio uses behavior change techniques such as “pros and cons awareness” to achieve an outsized impact in healthcare.
