Our Purpose

We can see people better than ever before.

The days of knowing people through averages, aggregates, and types are over. We have a new science of individuality that provides us with an unprecedented understanding of individuals on their own terms.

This is enabling us to transform how we teach, train, and heal.

Innovators are using this understanding to convert our cookie-cutter systems into highly personalized ones. As a result, medical systems are able to treat people based on their unique genomes. Education systems are able to teach people based on their individual abilities and interests. Workplaces are able to cultivate people in ways that harness their uniqueness and allow them to make their greatest contributions.

And, on the most fundamental level, people want something different.

Money, fame, power. That’s what we’ve been taught to orient our lives around in America. But our research shows that what we really want is something far more personal. An overwhelming majority of Americans now define a successful life as following their unique interests and talents to become the best they can be at what they care about most. Americans are hungry for a world that understands and values them. A world that is built to nurture and unleash their unique talents.

We believe that for the first time ever, we can do something about it.

Our purpose is to use this understanding of individuality to bend technology and social forces toward a world where people live fulfilling lives in a thriving society.



Our Priorities

Realizing our vision for the future requires transformation at cultural and systemic levels.



Change the cultural narrative around success.

We believe that building a world that nurtures and unleashes our unique talents starts with culture change. Our first priority is building social tools and engaging the media to inspire a new narrative about success. We’re working with leading culture designers, influencers and media pioneers to drive cultural shifts that flip the social pressure in our favor.



Transform public systems to meet our rising expectations.

Personal conviction and even public expectation alone, will not create a society that is responsive to individuality and supports fulfillment. We must also transform our systems to become more personalized. To meet this need, we are working to support and advance coordinated solutions at key levers within and across our public systems, with a focus on education, healthcare, and the future of work.
