Friend mode + Uno nights
Sonder
Friend-making built for the third-place gap, London-first.
“There's a big lack of third spaces in London — with Sonder, we're trying to solve that problem.”
— Lenard Pratt, co-founder
Our take
Closest of the six to PWC's own thesis — it names the third-place gap directly and leans on repeated, low-stakes formats (the Uno nights) rather than forced intimacy.
The right mechanic on paper: recurring, light, in-person. The question every app like this faces is whether the energy survives without the host in the room — the audience-vs-community test.
