    THE FOUNDER

    Juan Martin Gimenez Yunis

    The name started as a teenage forum handle: “Anon” from Anonymous culture, an extra “N” with a zero for the hacker aesthetic, and “IP” because — well, fifteen-year-old me thought it was cool. It stuck.

    By day I've spent the last decade in modern web stacks, from enterprise dashboards to startup MVPs. By night, I scratch my own itches and ship them here. If I wouldn't use it daily, I won't ship it.

    The bar is the same for everything: obvious to use, fast to start, honest about what it does. Some I give away. Others I charge for so I can keep building the rest.
