What 4s.link does

Japanese platform for hosting and finding startup and community events, with member groups and event calendars.

Summarised from the company’s public website. It may be out of date.

4s.link sent 7.1K visits to checkout pages over six months, about 1.2K a month, which puts it at #4,791 of 22,010 senders we traced.

100% of that went through Stripe Checkout. It uses a single checkout, so its buyers all pay through Stripe Checkout.

Similarweb files it under Business Services. It isn’t one of the AI products we classified by hand, so it doesn’t count toward the AI total.

Visits are modelled third-party estimates, not revenue. Read what this can’t tell you before you act on a single number.
