This section of the almanac covers agencies and platforms whose trade is bringing people together — social networks, companionship services, and introductory bureaux. Whether the enquirer seeks casual acquaintance or structured matching, the entries here represent the full range of the trade. Practitioners listed include both independent operators and established concerns serving international clientele. The section is arranged without sub-division, as the nature of the trade often overlaps between adjacent types. Consult individual entries for terms of service and operating territories before making contact.
