A device may access payment data of a first payment account and a second payment account that are associated with a first user and a second user, respectively, wherein the payment data includes descriptions of payments to vendors. The device may group the vendors into subsets of vendors based on characteristics of the vendors. The device may determine relative weightings for respective vendors within the subsets. The device may receive a request for a vendor recommendation for a meeting between the first user and the second user, wherein the request identifies parameters for the meeting. The device may generate the vendor recommendation for the meeting by identifying candidate vendors based on the parameters for the meeting and selecting one or more of the candidate vendors based on the relative weightings for the respective vendors.
