01 — Overview / Context
What was the problem we were solving?
Zenblen deployed robotic smoothie kiosks in gym environments to offer health-conscious, freshly blended nutrition options for gym-goers. Despite customer interest in healthier options, the kiosks struggled with low interaction rates. Our mandate was to understand why and to design solutions that could meaningfully shift behavior.
Kiosk placement did not offer any differentiation
No communication of the benefits to the users
Low trust in a new technology for nutrition and food.
02 — Research / Barriers
What did we learn from users?
We utilized a behavioral design approach, conducting deep qualitative research to understand gym-goers' motivations and adoption barriers. Some truths we discovered about the lived-experiences and expectations of customers' needs include:
350+
minutes of observation sessions
12+
contextual interviews conducted
45+
intercept conversations
2+
surveys completed
Key Barriers Identified

Gym-goers want snacks that clearly show how they're made and the real nutritional benefits they offer.

Lack of familiarity with new technology and products reduced trust and willingness to try them.

Gym-goers preferred their routines and didn't want to break patterns to interact with new solutions that were untested.

Different routines drive different nutritional needs, influencing how customers select snacks.
