Apostrofo was founded by a software engineer based in Puerto Rico, with experience building reliable, high-impact systems and a strong interest in human-centered product design.
The studio was created to focus on fewer projects, deeper thinking, and long-term ownership—combining disciplined engineering with real-world problem discovery.
KiaiLabs is the first product built under this philosophy.
