Josh Rosenthal and Brian Hardecker, co-founders of Index Industries

Josh Rosenthal, CEO, and Brian Hardecker, Chairman — co-founders of Index Industries.

Index Industries was founded on the thesis that the world's largest asset class has never had the investible infrastructure it deserves.

Josh Rosenthal brings deep expertise in onchain finance and capital markets, having led Polychain Capital as President through its growth into one of the most prominent crypto-native investment firms globally. Brian Hardecker built Longmark into a recognized institutional platform with $2 billion in U.S. residential assets under management, investment-grade ratings from S&P, Fitch, and KBRA, and a team with backgrounds at Blackstone, Goldman Sachs, and Starwood.

Their partnership reflects what Index Industries is: a company that can only exist at the intersection of institutional real estate and modern financial technology.

When index products came to equities, they didn't just add a new instrument. They changed how the world invests.

They made a vast, fragmented market something anyone could hold in a single position. Real estate has never had that moment, despite being the world's largest store of wealth. Index Industries exists to close that gap.

We're building for the next generation of real estate investing.
