Our friends at Cult.Repo launch their epic Python documentary on August 28th, 2025! To celebrate, we sat down with Travis Oliphant –creator of NumPy, SciPy, and more– to get his perspective on how Python took over the software world.

Stick around for the twist ending! We set aside Python and dissect Travis’ big idea to make open source projects financially sustainable through direct investment.
