Singh and Jain then started pitching to bigger corporates and airlines. This meant more emails and many cold calls to fix meetings and, when the two met the admin and heads of facilities, Jain says they liked the concept. “They were surprised that we were supplying the paper cups for free,” he says. The advertiser clients pay for the cups, and CupShup charges them per cup (not a lumpsum) anything between Rs.1.5-2 depending on the target audience, number of cities, campaign complexity and cup sizes. This revenue also includes printing and distribution cost. The cup sizes vary — 210 ml for flights, 150 ml for corporates, 100 ml for tea stalls in Tier-I cities and anywhere between 85-90 ml for tea stalls in Tier-II cities. The minimum order accepted is for 100,000 cups and, at times, corporates or airlines that serve in these cups charge a royalty for promoting other brands inside their premises. The start-up’s distribution network covers more than 2,000 corporates, 500 colleges, 5,000 retail tea vendors and three major airlines, and can send out a message to over five million working professionals.
