Brand activations and promo at events
A new advertising medium at events: after the light show every participant sees the sponsor’s promo in the browser: a free bet, coupon or campaign landing. A sponsor integration with measurable results: tests show 25–30% conversion from show participants

Calculated with the price calculator at 16.6% engagement (measured at the Krylya Sovetov vs Lokomotiv match, numbers breakdown) and 25–30% promo conversion. For a sponsor this is the upper bound: the show is usually paid for by the organizer, while the sponsor position is sold as a separate package
