Is founded and built the same thing?

No, "founded" and "built" are not the same thing. "Founded" refers to the establishment or creation of an organization, institution, or idea, often indicating the initial act of bringing it into existence. In contrast, "built" typically refers to the physical construction or development of something, such as a building or infrastructure, or the process of developing an idea or system further. While both terms can relate to the creation of something, they emphasize different aspects of that process.
