A discovery pass has no minimum number of businesses: it needs enough of them for a buyer to see the price paid back within a few visits. Around twenty businesses is a reasonable target for a first program.
Do the math from the buyer’s side. Assume a $50 pass and offers worth about $10 each. With twenty businesses, the pass holds $200 in offers and pays for itself on the fifth visit. With six, the buyer has to use five of the six offers just to break even.
Variety counts as much as volume. A coffee shop, a boutique and an activity give people reasons to go out at different times of the week.
For the first ones, start with owners who already know you and with one or two places the whole town knows. Their names on the list make the next meetings easier. Here is what you can tell them without overselling: no hardware to buy, an offer they set themselves, redemption on any phone, and a count of the visits the pass brings them.
Then fill in by category: one or two coffee shops, one or two restaurants, a boutique, an activity. A business says yes more easily when it is not one of five direct competitors. Talk to whoever makes the decision, and come during quiet hours.
The meeting takes ten minutes and a phone. Show the pass in your own Wallet, then how an offer is redeemed: the owner sees right away what the staff will have to do. Leave one page with the launch date, the businesses that have already agreed and what they commit to, then come back within the week.
The same objections come up. “I already give enough discounts”: suggest a free item rather than a percentage, which only costs the business what it costs to make. “My staff has no time”: redemption happens on a phone already in the shop. “People will abuse it”: every redemption is recorded, and a one-time offer works only once. “What if I want out?”: put the rule in a one-page written agreement reviewed by an advisor, since Pass Holders paid for a list of offers.
