Big Fun Museum: the crew that tripled its daily leads by learning from the dashboard

The museum asked us to drive visitors with 10,000 hand-to-hand flyers. A crew of two Brand Missionaries covered Gracia, Sants and Ciutat Vella across 9 distribution days in August 2026, with 149.7 GPS-verified km. This is where the dashboard earned its keep: the data showed 70 percent of leads arrived between 2pm and 9pm, we reassigned zones and time slots on the fly, and the crew went from around 13 leads a day at the start to an average of 42 over the last four days, peaking at 64. At close it had 310 verified leads. And the response is still alive: 21 more leads since the last flyer, 331 to date. Paper stays in the home; the response does not end when the distribution does. 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.

Molan Los 90: 6,000 flyers in 4 days to fill a festival

Deep Delay Management asked us to amplify their reach in Cadiz for their 90s music festival. Three distributors with GPS covered the city hand to hand and delivered all 6,000 flyers in 4 days. The campaign QR logged 289 verified visits to the ticket page, a 4.8 percent response rate. During the 4 distribution days the festival sold 361 tickets online, nearly one in five of its total sales (client data). Response climbed every day, with almost half of the scans between 6pm and 9pm.

The flyer that was still bringing in students two months later

A fitness and wellness centre with 25 years in Barcelona wanted to fill its Poblenou classes. We door-dropped 5,000 flyers across the neighbourhood, letterbox by letterbox, in one week. The interesting part came afterwards: people kept the flyer and kept responding for nine weeks, with a second surge in late July, right when September classes come to mind. More than 200 verified responses in total. It is the best example of paper's long tail: a QR that stays live keeps working.

Barcelona Beer Festival: 345 leads in 2.5 days

A flyer campaign with QR tracking in the neighbourhoods around the festival venue. The QR on each flyer measured response by zone and by day: 345 leads captured in 2.5 days of distribution, with the data visible in the client dashboard in real time. The key takeaway: better neighbourhood targeting generates more response than increasing flyer volume.
