Summary. Stealth NY is a 5,000-square-foot sneaker store in Brooklyn with basketball courts inside it. Rather than hand court bookings to a third-party scheduling tool, the owner, Armani, had a booking app built on Whop‘s API and recorded 6,000 bookings in the first two weeks. If you run a shop with any bookable space, a court, a studio, a chair, a class, this is the mechanism to study.
What Stealth NY was doing before Whop
The store sits at 59 Noble Street in Brooklyn. It sells sneakers, and it has courts that people want to book and pay for.
Armani’s requirement, per Whop’s write-up, was to manage court bookings and payments without surrendering the brand to a third-party booking tool. The write-up does not describe a previous booking system, only that requirement.
What changed on Whop
Stealth built its own court-booking app on Whop’s API. Whop handles the money; Stealth owns the screen the customer sees.
The pieces the write-up names: checkout sessions to take payment, webhooks to tell Stealth’s app when a booking is paid, confirmations to the customer, and a customer dashboard where bookings live. None of that sends the customer to another company’s domain.
Tiana Porta of Whop describes the intent: “The goal was to give Stealth full ownership of their booking experience without rebuilding what Whop already does best.”
NBA player Jose Alvarado is named in the write-up as a partner and friend of the store. It does not describe his role in the app.
The numbers
6,000 bookings recorded in two weeks. A 5,000-square-foot location. The write-up also cites 540 outdoor basketball courts across New York City as context for demand.
What it does not state: the price per booking, revenue, court utilization, or any financing. Treat 6,000 as a volume figure, not a revenue figure.
What I would tell a local retailer to copy
Bookable space is a second revenue line that most stores leave idle. A court, a back room for classes, a chair for fittings. Stealth’s 6,000 bookings in two weeks says the demand was there before the app was.
Keep the booking on your brand. Every third-party scheduling tool that emails your customer from its own domain is training that customer to remember the tool, not you. You do not need a custom app to do this; Whop’s stock checkout links and storefront work for a store without a developer, and the API route is for stores that have one.
Measure the booking, not the visit. Google Analytics 4 and Tag Manager with a conversion event that fires on the paid booking, fed by the same webhook the app uses. That is the number you compare week to week.
Then make the proof public. One canonical page for court booking, with the count, the photos, and the players who show up. Armani’s stated motive is community: “I want to put fly clothes out at affordable prices, and do right by my community.” Post the court footage, and put Dollar-a-Day boosts behind the clips that already got shares on their own.
Who this is not for
Whop is a checkout, financing, affiliate and storefront layer, not an inventory or accounting system, and not a field-service app. Stealth’s route needed a developer to build against the API. The base rate is 2.7% + 30¢, 20 basis points under Stripe’s 2.9% + 30¢; the optional layers, managed tax at 2%, orchestration at 0.8% and billing at 0.5%, can push the stack above Stripe. Financing requires $30,000 processed from 10 or more customers in 90 days and a dispute rate under 2%, and is unavailable to gambling, sports betting, trading signals, credit offers and adult categories; this story does not involve financing.
If you were going to use Whop anyway
If you were going to sign up for Whop anyway, sign up through my link, dennisyu.com/go/whop, or send me your business name and email and I will submit the referral. Whop pays me a share of its profit on your account; your rate is the same 2.7% + 30¢ either way. In return my team at Local Service Spotlight sets up the AI agents that audit your public reputation, fix what they find, and keep it maintained: a personal brand analysis, Google Analytics 4, Tag Manager and Search Console with conversion events that actually fire, a Content Factory that turns one recording into a definitive article, clips and posts, and a weekly Metrics, Analysis, Action report. That is the work we normally charge local retail businesses for.
