KF.SocialHow Timeleft works
Timeleft seats you at a small dinner, described on its homepage as "five new faces over good food", which is six at the table. It groups people by age range, personality and language, and its homepage says it runs in 48 countries and more than 160 cities. You do not pick who is at the table. It uses a subscription model, in one, three or six month periods, and its help centre says available options vary by region and are displayed during sign-up rather than published on the site. Food and drinks are paid at the venue.
How Meetup works
Meetup is a directory of interest groups and events, running since 2002, from small book clubs to gatherings with several hundred people. You browse, pick an event and show up. The range is the real advantage: browsing London on 4 September 2026, the categories included language exchange, technology, dancing, sport, art and culture, games and science, and most listings cost nothing to attend.
Two things about the cost are worth knowing, because "free to join" is now only part of the picture. Meetup sells a member subscription called Meetup+, and its help centre article "Meetup+ vs. Free Plan Members" describes the free tier as "the limited free plan": full access to the attendee list, member profiles, the "Who will be there" feature, unrestricted direct messaging and waitlist priority all sit behind Meetup+. Separately, individual groups can charge member dues set by the organizer, and Meetup says those groups show a "Request to join" button rather than the usual "Join group". So the free plan is real and useful, and it will not tell you who is coming.
The real difference: a matched table against a chosen event
At a table of six, everyone talks, because there is nowhere else to be. At an event with two hundred people you have complete freedom and no guarantee you speak to anybody. Neither is better in the abstract. The question is how much energy you have on the night: a crowd asks you to do the introducing, and a table has already done it.
Where KF.Social fits
KF.Social is a third shape: a matched dinner like Timeleft, London only, priced per evening rather than by subscription. A table is six people, and a seventh booking is not turned away because we open another table of six. It is 15 pounds for the seat, published before you pay, plus your food and drinks at the restaurant. The restaurant lands about six hours before and who you are sitting with about an hour before, when the group chat opens. Cancel more than 72 hours ahead and the 15 pounds returns to your card, between 72 and 24 hours it returns as KF Points, and inside 24 hours it does not. We also run clubs, which are free to attend, so the people you meet have somewhere to keep meeting.
Which should you pick?
Pick Meetup for choice, for a specific interest, for spending nothing, or if you are not in London. Pick Timeleft for a matched dinner in one of the many cities it covers, particularly if you live there and will go often enough for a subscription to pay for itself. Pick KF.Social if you are in London for work and want a matched table you pay for one evening at a time. If that is you, see the tables coming up in London.
