Fifty Years is an operator-heavy venture fund founded by repeat entrepreneurs that exclusively backs companies tackling civilization-scale problems like climate, health, and food systems, inspired by Winston Churchill's 1931 essay "Fifty Years Hence" and applying a strict "Mr. Burns test" where even a villain would recognize the social benefit. The fund operates a quasi-company builder program called "5050" that helps scientists and engineers become founders, while investing disproportionately in pre-product deep-tech moonshots rather than conventional software companies.
