Property technology (also known as by the portmanteaus proptech, PropTech, prop-tech and also known as real estate technology) is used to refer to the application of information technology and platform economics to the real estate industry.[1][2] Property technology overlaps with financial technology, including uses like online payment and booking systems.[3][4] Grammatically, the portmanteau "proptech" is formed from two common nouns: "property" and "technology." As such, capitalizing it is grammatically incorrect (just as "email," "romcom," "webinar," and other portmanteaus are all lowercase).[5]
