Thriving is more than wellness, it’s the science of building the energy, resilience, and emotional fitness to fully engage in life. Backed by years of neuroscience research, SIX helps people measure the moments that matter most and understand what truly fuels positive mood, purpose, and sustainable well-being.

Strong relationships are one of the most powerful tools we have for protecting emotional health, but only if we nurture them before crisis hits. This piece explores the idea of “hugs not drugs” and how neurotechnology can help us objectively understand when the people we care about are thriving or struggling, so we can show up at the moments that matter most.

Thriving isn't just personal. It is deeply social. Neuroscience shows that people who experience at least six meaningful Key Moments a day, most often through connection with others, have higher mood, energy, and engagement. The SIX app makes this visible by measuring emotional impact and helping you stay connected to the people who matter most.

How does this work?
Your brain tells a story. Your smart watch is ready to listen. After more than 20 years of published, peer-reviewed research, we’re connecting the two. Now, using everyday wearable devices to closely monitor cardiac rhythms, we can trace the simultaneous release of oxytocin and dopamine throughout the day. Our sophisticated algorithms illuminate the pathway from body to brain, giving you all the information you need to understand and act on these high-value moments.
