Inspiration

As MBA students, our days are packed with classes, recruiting, and nonstop events. We always wanted to journal this experience but never had time to actually sit and reflect. That led us to a simple question: What if gratitude could be effortless? Moreover, what if AI could help us pause, reflect, and share meaningful moments even in a busy, high-achieving environment? Neuroscience shows that small gratitude practices reduce stress, strengthen emotional regulation, and increase long-term well-being. We wanted to build something that makes that practice easy and seamless.

The Problem

High achievers rarely slow down to reflect. Gratitude is proven to improve mental and physical health, but it’s the first habit people abandon when schedules get intense.
