Built
in order.
A San Antonio studio that builds and runs its own companies. Five so far. Each one earns its place before the next begins.
A sunflower packs its seeds 137.5 degrees apart. Every seed, every time, because nothing else wastes so little. This studio runs on the same arithmetic. One founder. No outside money. Five companies that each had to earn the next number.
Castilloworks is a founder-led studio in San Antonio, Texas. Meet the founder.
Iron Star
Doorstep trash valet and grounds upkeep for apartment communities in San Antonio. The unglamorous work, done like it matters.

The sequence doesn’t stop at five, and neither does the studio. When a sixth company earns its place, its number is sitting right there.
