    OUR VISION

    Ironstone seeks to identify disruptive companies that have the potential to grow for decades. Hambrecht collaborated for more than twenty years with Harvard Professor Clayton Christensen (died 2020), author of "The Innovator's Dilemma," to implement Christensen's "Disruption Theory."  Disruptive companies start at the low end markets and target underserved customers in new markets at price points considered unattractive by larger, more established companies.   

    Ironstone (IRNS) holds stakes in Tango,  Aristotle (PredictIt) and Buoy Health today as potentially disruptive growth companies.
