Most of what this desk covers is a paywall you can walk away from. Kasalyst is the other shape: a private members’ club for singles aged 35 and over, taking money now for a thing that has not opened yet. Its own homepage carries the banner “LAUNCHING AUTUMN 2026” and, further down the same page, the line “membership open now”, and the founders, Kate Sime and Sarah Nicoll, sign the site as Kasalyst Ltd.
Credit where it is due — the membership page is more legible than almost any dating subscription we have priced this year. Read on 6 September 2026, it lists a joining fee of “£95, one-off”, membership at “£60 a month or £600 a year · cancel anytime”, and first payment “On acceptance”. Events are extra: tickets, the page says as a guide, “will typically range from around £50 to £125”. A Kasa & Co guest pass is £25, refundable against a guest’s joining fee if they sign up within three months.
The Founding Hundred has a date on it
There is a cheaper door, and it closes. The first 100 members, “until 31 October”, get the joining fee waived and membership at £40 a month or £400 a year, locked for as long as the membership runs continuously. Founding Members pay nothing until the events calendar launches, which the page puts at November 2026. Standard members joining from launch do not get that grace period.
Where the rooms are
Here is the bit a subscriber outside the M25 should read twice. The membership page states plainly that “our initial events will be London based, in spaces chosen for their character and warmth”. The about page sells “London’s most beautiful rooms”. No other UK city appears in the Kasalyst pages we could open on 6 September 2026. A £60 monthly fee is a London fee wherever you happen to live, and a Manchester or Glasgow member is buying train tickets before they buy a dinner.
Two other things worth stating flatly. The vetting is real work, not a badge: an application form, a chat in person or by video, and one piece of ID. And the about page limits the club to “discerning heterosexual singles aged 35 and over” — their wording, not ours.
The pricing above is a live offer with a 31 October cap on the cheaper tier, and it can move. If you are weighing a recurring charge for something that has not launched, the renewal-reminder rules we covered last month are a useful reminder of how little of this category tells you it is still billing you. Check the terms yourself before the card details go in.
