Developed by Harvard-trained dermatologist Dr. Iris Rubin, SEEN recognizes that haircare is an essential part of good skincare. SEEN promotes healthy hair AND skin, with patented and award-winning formulas that are clinically proven to be non-comedogenic (won’t clog pores), and safe for sensitive skin. After experiencing breakouts that were traced back to a surprising source - the haircare products at her salon, Dr. Rubin set out to create a solution. It took 4+ years and countless lab samples to bring SEEN to life, and Dr. Rubin has done more than create clean, effective, luxurious haircare products that respect the skin. SEEN is routinely described by our customers as life-changing, and game-changing. SEEN is also loved by dermatologists (and samples to over 1400+ dermatology practices), backed by a syndicate of world-class investors, including some of the most successful entrepreneurs of our generation, as well as Harvard dermatologists and scientists. SEEN was built on the belief that you deserve to have both gorgeous hair and healthy skin—and you should not have to compromise. Our mission is to help everyone feel SEEN for their best self.

We exist to help the world’s top entrepreneurs, operators and investors attain the extraordinary. We do this by providing enduring capital and also by obsessing over doing everything else we can to enable them to achieve their full potential. In doing so, we seek to invert the traditional relationship between LPs/GPs and shareholders/companies, which too often lacks animation and runs counterproductive to the spirit of partnership. In every aspect of our design, we are purpose-built to accelerate the pursuit of the investment partnership ideal without institutional constraints. If we succeed, the result will be the curation of some of the highest quality company and fund holdings globally. We exist to serve a small number of individuals and families. In form, we are a private holding company​, ​managing substantially all of the two founders capital alongside a more modest proportion from some other shareholders. In function, and as our name conveys, we are an intimate ​grove (not a forest) comprised of like-minded ​sowers​, many of whom are leading investors and company operators. Our shareholders are trusted friends and co-conspirators in work and life. They share in our values and collectively comprise an ecosystem of people in whom we have the utmost admiration. We exist to serve the greater good. The essence of Sator Grove is first a flourishing community that seeks to do good together and second an investment company. Whether through the capital we provide or the people with whom we collaborate, our aim is to ‘sow good seeds’ that grow into win-win outcomes for all of our constituents, including society and future generations. Importantly, we’ve established Sator Grove such that from Day 1 our largest economic beneficiary is the ​Sator Grove Foundation. ​In time it will become a powerful charitable force emerging from the success we achieve together as it advances the needs of children globally through poverty alleviation, education and healthcare.
