Fortive, the company they co-founded, has grown into a diversified industrial conglomerate with a market capitalization in the tens of billions of dollars.

Their ability to identify and scale businesses with strong fundamentals has been central to building this empire, and the company continues to expand through both organic growth and strategic acquisitions.
Investment Strategy and Portfolio Companies
The Rales brothers employ a value-oriented acquisition strategy focused on companies with strong underlying assets but operational inefficiencies.
