Big Fun Museum: the responses keep coming in
Big Fun Museum · Barcelona
Hand to hand · 19–27 Aug 2026
COMPLETED
+36 LEADS AFTER THE LAST FLYER
The museum asked us to drive visitors with 10,000 hand-to-hand flyers across Gracia, Sants and Ciutat Vella. The dashboard showed where and when people responded, we reassigned zones and time slots on the fly, and the crew went from about 13 leads a day to an average of 42 over the last four days. At close: 310 verified leads. Today: 346, because paper stays in the home and the flyer keeps working.

GPS
Distribution ended on 27 August, the response did not: 36 more leads have arrived since the last flyer, 346 in total to date, and the figure updates itself straight from the platform. And each lead usually means more than one ticket: people visit a museum like Big Fun as couples, families or groups of friends, almost never alone.

Case study
The flyer that was still bringing students two months later
Fitness & wellness · Poblenou
Operating in Barcelona for 25 years · June 2026
9 WEEKS OF RESPONSE
A fitness and wellness centre with 25 years in Barcelona wanted to fill its Poblenou classes. We delivered 5,000 flyers to letterboxes across the neighbourhood, street by street, in one week. The interesting part came later: people kept the flyer and carried on responding for two months, with a second surge in late July, when September was on their minds.
Cumulative responses
Distribution ended in week two. Seven weeks later the same flyer fired again: 30 responses in the last days of July.
