99% Invisible is a tiny radio show about design, architecture & the 99% invisible activity that shapes our world.  Each episode is a sound-rich deep dive into a single topic. With more than 3 million downloads per month, we routinely rank in the top 10 arts podcasts and top 20 podcasts overall in iTunes.


The show started life as a project of KALW public radio in San Francisco and the American Institute of Architects in San Francisco. We are distributed by PRX on PRX Remix and public radio stations around the country. Roman Mars is also a founding member of the podcast collective, Radiotopia.


We are a completely independent production and raise all of our funds directly from the listeners, most notably from our record breaking Kickstarter campaign, and from podcast underwriters.


Praise for 99% Invisible:


“99% Invisible…is completely wonderful and entertaining and beautifully produced…”
-Ira Glass, This American Life


“We think what he’s doing is inspiring. It has a kind of rhythm and musicality that you don’t normally find in radio or podcast storytelling.”
-Jad Abumrad, Radiolab


“Roman Mars lights the radio. His pieces conjure other worlds, grapple with big ideas, make sound three dimensional. They are smart and funny and original. The Kitchen Sisters would like to be Presidents of his Fan Club.”
The Kitchen Sisters, Peabody Award-winning producers for NPR


“I love the show. It’s wonderful. [It] actually reminded me of why I love radio.”
-Jonathan Goldstein, CBC’s WireTap


“Mars is the Ira Glass of design.”
-Allison Arieff, design columnist for The New York Times

Roman Mars (@romanmars) is the creator of 99% Invisible, a short radio show about design and architecture. With over 30 million downloads, the 99% Invisible podcast is one of the most popular programs on iTunes. Fast Company named him one of 100 Most Creative People in 2013.

Sam Greenspan (@samlistens) left his job as a staff producer at NPR to work out of a tiny room in Roman’s back yard. His pursuit of a good story has lead him to debate the merits of capitalism waist-deep in a dumpster, talk street soccer with displaced Palestinians in Brazil, and investigate claims of secret music inside of public transit systems. (Twice.) He has lived and made radio across the eastern seaboard, and now resides in Oakland. Hear more at samgreenspan.org. Photo credit: Catalina Kulczar




Katie Mingle is 99% Invisible’s senior editor but she also reports and produces for the show. She has lived on the Gulf Coast, the East Coast, the Third Coast, and has finally come to settle on the West Coast (Oakland). She comes to 99% Invisible from the Third Coast Festival, where she spent a few years producing Re:sound, eating tacos, and shivering. You can hear more of her stories at her website, katiemingle.com




Avery Trufelman (@trufelman) thought she wanted to be a designer, but nah, she’d rather make radio stories about design. An obsessive podcast listener, Avery was a fan of 99% Invisible long before she joined the show as a producer. Her favorite font is the official typeface of Sweden, Sweden Sans.




Kurt Kohlstedt (@kurtkohlstedt) is a lifelong public radio fan and has secretly wanted to work on 99% Invisible for years. He joins the show from Minneapolis as digital director. While finishing his graduate thesis on shipping container architecture and nomadic urbanism in Seattle, Kurt decided to pursue design media, founding WebUrbanist in 2007 and various other online publications since.
