A dining app with a blockchain hidden inside
Blackbird Labs is trying to answer a question that has vexed the restaurant business for as long as there have been restaurants: what makes a guest come back? Founded in 2022 by Ben Leventhal - who previously co-founded the restaurant-media site Eater and the reservations platform Resy - the New York company pairs a consumer dining app with a payments-and-loyalty network that runs, unusually, on its own blockchain.
The pitch to diners is disarmingly simple. You walk into a participating restaurant, tell the server you are paying with Blackbird, and you earn a rewards currency called $FLY. Sometimes that unlocks a last-minute table, an off-menu dish, or a perk you did not expect. There is no card to carry and, notably, nothing that feels like crypto. The wallet is there; you just never have to think about it. That design choice - hiding the machinery - is the reason writers have described Blackbird as a consumer-crypto app that ordinary people actually use.
The pitch to restaurants is where the economics get interesting. Because Blackbird can process payments through its own network rather than routing everything through traditional card rails, it charges operators a flat fee of roughly 2% per transaction - about a point and a half below the 3.5-4% that card providers typically take. On the thin margins that define the restaurant industry, that gap is not a rounding error. Restaurants also get something they rarely hold onto in an era of delivery apps and third-party platforms: ownership of their own guest data and the relationship that comes with it.
Two sides of the same table
Blackbird operates a classic two-sided network, and its product decisions follow from that. On one side are diners, who use a free mobile app to check in, collect $FLY, unlock perks, and settle their bill. On the other are restaurants and cafés, which use Blackbird to drive repeat visits and to process payments at a lower cost than the incumbents charge.
The company has been deliberate about geography. Rather than spreading thin across the country, it went deep in three markets - New York, San Francisco, and Charleston, South Carolina - because a loyalty network only works when there are enough nearby restaurants to make the rewards meaningful. Density, not breadth, is the early game.
For diners, the appeal is tangible: a rewards balance that carries across a whole city's worth of restaurants, plus access - priority tables, off-menu items - that money alone does not always buy. For operators, it is margin and data. The two align around the same goal, which is retention.
By its 2025 Series B, roughly 1,000 restaurants were on the platform, and Leventhal signaled plans to expand into additional cities with the fresh capital.
Why the fee matters
The stack, from app to blockchain
Blackbird App
Consumer app to check in, earn $FLY, unlock perks like priority tables and off-menu items, and pay the check.
Blackbird Pay
Pay your bill in USDC or $FLY. Restaurants pay a flat ~2% fee instead of standard card rates.
$FLY
The native rewards currency, earned by dining and usable across the network - restaurants can even pay platform fees with it.
Flynet
Blackbird's own blockchain mainnet - the rails powering $FLY, loyalty, and payments across the platform.
Blackbird Club
A tiered, cross-restaurant membership with concierge priority access to tables at 100+ Club restaurants.
Coffee Club
Earn 10% back in points when you pay with Blackbird at participating coffee shops and cafés.
Owning the rails, not renting them
Most loyalty programs are a tax on attention - another card, another login, another password to forget. Reservation and marketing platforms, meanwhile, tend to sit between a restaurant and its guests, keeping the relationship for themselves. Blackbird's design pushes against both patterns.
First, it collapses payment and loyalty into a single tap, so earning rewards requires no extra step. Second, it hands the guest profile back to the restaurant rather than hoarding it. Third - and this is the ambitious part - it built its own network, Flynet, rather than launching on someone else's chain. Owning the infrastructure is what lets Blackbird price below card networks and design loyalty that moves freely across restaurants instead of being locked inside a single brand's program.
The competitive set, then, is broad: reservation and loyalty incumbents like Resy and OpenTable, payment processors whose fees Blackbird undercuts, and the delivery and marketing apps that stand between operators and their customers. Blackbird's wager is that a diner-facing app people enjoy, combined with economics restaurants prefer, is a more durable position than any one of those alone.
Where it fits
The revenue model is B2B2C. Diners use the app for free; Blackbird makes money from the transactions restaurants process through it, taking a flat fee of roughly 2%. Around that payments core sits the loyalty and membership infrastructure - $FLY, Blackbird Club, Coffee Club - that gives operators reasons to keep guests coming back and gives Blackbird a reason to be more than a cheaper card swipe.
The market it is stepping into is large and fragmented. Restaurant technology today is a patchwork of reservation systems, point-of-sale software, delivery marketplaces, and standalone loyalty apps, each taking a slice and, often, a piece of the customer relationship. Blackbird's expertise - built from Leventhal's years across Eater and Resy and a team that blends hospitality operators with payments and crypto engineers - is aimed at stitching two of those slices, payments and loyalty, into one experience that a diner enjoys and a restaurant can afford.
Whether a rewards token and a purpose-built blockchain are the right way to do that is the open question the industry is watching. What is clear is the shape of the bet: reduce the friction of loyalty to a single tap, price payments below the incumbents, and give restaurants back the guest relationship the rest of the stack quietly took.

Ben Leventhal
Blackbird is Ben Leventhal's third act in and around the restaurant business. He co-founded Eater, the restaurant-media site later acquired by Vox Media, and then Resy, the reservations platform American Express bought in 2019. That history matters: he has spent two decades watching, from different angles, how restaurants find guests, keep them, and lose margin along the way. Blackbird is his attempt to fix the loyalty-and-payments layer he saw wear thin from the inside.
