Arduino is owned by the Arduino Group, which is a community of developers, designers, and manufacturers. Originally, Arduino was founded in 2005 by Massimo Banzi, David Cuartielles, Tom Igoe, and Gianluca Martino. The ownership of Arduino has evolved over time and includes several stakeholders:
1. **Arduino LLC:** Based in the United States, this entity manages the Arduino brand and oversees operations and development in the Americas.
2. **Arduino Srl:** An Italian company responsible for the hardware and software development of Arduino products. This entity was originally led by the founding team and operates out of Italy.
3. **Arduino SA:** A company based in Switzerland, which was established to manage the European operations of Arduino. This company was formed in 2019 to streamline and centralize the European business operations.
The Arduino ecosystem is supported by a wide range of contributors and partners, and the project remains a collaborative effort involving many individuals and organizations dedicated to open-source hardware and software.
