Ventureology

How the man who scaled Sears turned his fortune into nearly 5,000 schools, then gave it away on a deadline.

Julius Rosenwald never invented anything. He bought a quarter of a struggling mail-order house in 1895 for $37,500 and made the founder optional. When the post-war crash of 1921 nearly killed Sears, Rosenwald backstopped the company out of his own pocket and made the clerks and packers who had bet their savings on it whole before himself, to the exact dollar.

This is the story of one of the most unsung philanthropists of the 20th century.

What is Ventureology?

The stories of funders and builders who forged markets.
Ventureology is a deep-format podcast covering how venture capital markets outside Silicon Valley and New York originated, grew, and scaled. Each season traces a single city's entrepreneurial history from its earliest foundations to its modern ecosystem — the founders who built companies from nothing, the capital that funded them, and the infrastructure decisions that compounded into billion-dollar industries.

Season One: Chicago. From 82 grain merchants who founded the Chicago Board of Trade in 1848 to the $106 billion exchange conglomerate, $184 billion private equity firms, and high-frequency trading empires that define the city today — this is the definitive history of how Chicago became the backbone of global finance.

The full written episodes — with source citations, maps, and data the podcast can't fully unpack — are available at ventureology.co.

New episodes drop every 1-2 weeks during each season.
