Beautiful, sustainable jigsaw puzzles.
Welcome internet traveler… you’ve reached my information superhighway.

I’m a post-exit founder with a passion for internet rabbitholes, making films, retro games, and useless websites.
Professionally I found my stride in viral and paid media, managing $400m in marketing spend. In 2022 I went viral on how to code using AI using GPT-3.5, before vibe coding existed.
I oversee Hypertext Foundation, where we partner with Naive Yearly and others who love the internet. I manage investments at Interrobang, where we focus on emerging assets and pre-IPO rounds.
I grew up in Florida, have had a cat named Hobbes (RIP), and fall asleep listening to audiobooks.

I’ve started over a dozen companies, some of which were acquired and others that were hilarious failures learning opportunities.

Nerdy things
(∩｀-´)⊃━☆ﾟ.*･｡ﾟ
I’ve been fascinated with crypto since 2013 when I did my first bitcoin transaction just so I wouldn’t become an old man left in the dark ages. Been through a fair share of rug pulls.
AI Coding: In 2022 I became an AI “influencer” for a bit on TikTok and got a few million views on AI coding videos when that was a novel thing. I knew I had achieved True Virality because a friend of Emily mentioned a video they saw and she was like, yeah, that’s Josh and I edited it.
Text-to-Image Gen AI: 2023 was a year of playing with image generation and I made and launched tens of thousands of AI-made ad creatives. This culminated with the book Rate Limits and contributed to Brainjolt’s acquisition in 2024.
Kids Games: I applied both of the above skills in 2024 to make simple kid games for Zizi. You can read more about it in Retro Games and 4-year-olds.
An… enigma?

Someone once told me ”you’re an enigma, man” in the most California voice I’ve ever heard. Was it a compliment or a criticism? I never asked.
