Cobu

Cobu is a Boston-based proptech company that turns apartment residents into a real community - and turns that community into occupancy. Its resident-powered, AI-enabled platform runs building-wide chats, interest groups, in-person events, and always-on Google review and referral outreach, backed by a team of virtual community managers. For renters it fights isolation; for owners and operators it drives signed leases, higher renewals, better online reputation, and less busywork for on-site teams. Founded in 2018 as Doorbell, Cobu is used across dozens of U.S. states and by many of the country's largest multifamily operators.
