Who's behind Substash?

Hey, I'm Chris, the creator of Substash. I've been making stuff online since 2009.

Most recently, this was a VC-backed AI startup. After about 3 years, I burned out… spectacularly. I decided to wind things down and it took me half a year to recover, during which I had time to rethink my priorities.

Nowadays, it feels like everything’s a subscription. While it's convenient, this also means that so much money gets wasted by signing up for things and forgetting to cancel. I know I’m not alone, so this seemed like a good thing to build: straightforward, useful, and solving an immediate problem.

While Substash was first built for myself, I hope you find it useful too.
