Hakema is an online booking solution that allows buyers and sellers on classified advertising websites to efficiently schedule meetings like property viewings. It was developed for Oikotie, Finland's largest real estate classifieds site, to address frustrations with contacting sellers by phone or email. During a successful pilot, Hakema increased engagement and led to 2.2 times more bookings than contact forms. Classified sites can now offer Hakema's integration to improve leads, on-site time, and advertiser value through a better connection between buyers and sellers.
