SmartRent, an access control company for rentals, announced a new product today, Alloy Access, which expands the company's reach into full-building access control and self-guided tours. The company has raised more than $41.5 million in funding from Bain Capital Ventures, Amazon's Alexa Fund, RET Ventures, and Starwood Capital Group. The new product brings SmartRent's platform to the full building, allowing owners and residents to remotely and automatically allow delivery drivers, mailpeople, and guests into the building. The platform also allows for self-guided apartment tours, which CEO Lucas Haldeman said is driving major demand for the company.
