Castle makes residential property management affordable and scalable. Their platform handles the hard work of landlording—finding tenants, collecting rent, and coordinating maintenance—allowing rental owners to sit back, relax, and collect on their investment. Some task, like rent collection, are automated entirely via software; for those like maintenance where a physical visit to the property is required, their on-demand labor network steps in. Their mission is to rationalize the rental process. They are taking property rental—an experience that’s near universal, yet near-universally unpleasant—and redesigning it from the ground up to be simpler, smoother, and more efficient.
