Building differently

El Sueno is a one-person studio powered by AI collaboration. Founded by YJ Kim, a UC Berkeley grad who left the VC-backed startup world to build calmer, more sustainable products.

We believe the best software comes from patience, taste, and genuine care for the people who use it.
