My name is Max Nussenbaum, and this is my web site.
I’m Head of Product at Upside, where we’re building private referral infrastructure for independent professional services businesses. I also write Candy for Breakfast, an email newsletter about funny feelings, weird careers, making art, and how to be alive, delivered every other Sunday.
Before Upside, I worked at On Deck, where I built products for founders and ran On Deck Writers, which was kind of like a startup accelerator for internet writers. Before that, I was cofounder and CEO of Castle, a property management startup which had a brief moment in the sun before collapsing in 2018.
At various other points in my life I’ve been a graphic designer, web developer, fiction writer, mediocre freestyle rapper, game show contestant, musical lyricist, and probably a few other things.
In a past life, I was a 2012 Fellow in Venture for America’s inaugural class, where I bought and restored a formerly-abandoned mansion in Detroit with some friends who later became my Castle cofounders.
This web site has been around in some form or another since 2001, when I bought a book about HTML and read it instead of paying attention to my fifth-grade teacher.
