In various embodiments, a processor can receive an electronic request from a merchant device, which identifies a team deal. In various aspects, the processor can access a plurality of transactional browsing histories that are recorded by a respectively corresponding plurality of monitorial browser extensions, with each monitorial browser extension being installed on a respectively corresponding client device. In various instances, the processor can execute a machine learning model on each transactional browsing history, thereby determining whether the transactional browsing history demonstrates interest in the team deal. In various cases, for each transactional browsing history that demonstrates interest in the team deal, the processor can invite a user of a client device corresponding to the transactional browsing history to participate in the team deal.
