YJ Kim
Founder of El Sueno LLC and Hypnothera
I build calm, focused consumer software, using AI where it genuinely helps. My main work is hypnosis and habit-change apps, plus a few tools for things I care about, like BJJ and learning languages.
01About
I'm YJ Kim (Young Joong Kim), founder of El Sueno LLC, an independent product studio. I studied at UC Berkeley, worked at Parity Technologies, and co-founded Boardroom Labs, which raised funding from Standard Crypto and IDEO Ventures.
After years in venture-backed startups, I chose to build differently: a small, self-funded studio where I work alongside AI collaborators to ship products that help people, without the pressure to grow at any cost.
