How It Works
.avif)
Why companies choose Secret Sender
Most team building lands somewhere between a trust fall and a slideshow. Secret Sender does something different. Central Amsterdam becomes the board, with no venue to book and no setup to manage. The competition between groups breaks the ice naturally. People loosen up because they’re too busy trying to win.
Particularly well-suited for: international teams, onboarding events, department days, conference side programs, and end-of-year outings. The multilingual format makes it easy for mixed-nationality teams common at companies like Adyen, Booking.com, and other Amsterdam-based international organizations.
Run together with our partner
Secret Sender for Groups is run together with our partner Mystery City, who specialise in city-based puzzle adventures for corporate groups. Sherlocked recommends this experience as part of our wider range of team building activities in Amsterdam. Group bookings are handled directly with Mystery City.
