The expense report may be corporate America's most durable work of fiction. A traveler buys a ticket, changes it in an airline app, sleeps in a hotel, loses a receipt and, days later, reconstructs the trip for a finance system that was never present. Somewhere else, a travel manager is trying to determine whether the unused ticket became a credit. The airline has one version of events, the agency another, the card network a third. Blockskye starts with a radical-seeming suggestion: perhaps everyone should be looking at the same trip.
Founded in Boston in 2017 by Michael Share and Brook Armstrong, Blockskye is both a global travel management company and the infrastructure beneath one. It connects corporate booking, agent service, airline and hotel content, payment, expense and reporting on a tamper-resistant ledger. The traveler sees KAYAK for Business. The finance team sees transactions tied to policy and project codes. Suppliers see reservations and settlement. Blockskye's machinery is meant to keep those views synchronized.
01 / The hidden itinerary
A booking is really a chain of financial events
Traditional corporate travel is less a single system than a relay race. A global distribution system passes inventory to an online booking tool. A travel management company services the reservation. A card pays the supplier. An expense platform asks the employee to explain the card charge. An ERP eventually records it. Every baton pass creates another database, fee and opportunity for the record to go stale.
That architecture was reasonable when airline inventory lived in a few central systems and paper tickets were literal. It is awkward now that carriers publish richer offers through New Distribution Capability, travelers change flights in supplier apps and finance leaders expect live data. A direct booking can be cheaper or better tailored, but it can also slip outside policy, reporting and duty-of-care systems. Blockskye's proposition is not simply “book direct.” It is “stay connected when you do.”
02 / The product stack
The blockchain is backstage, where it belongs
Blockskye's most practical product decision is to make its blockchain boring. There is no token to buy and no wallet for an employee to understand. The ledger acts as a common, tamper-resistant record for booking and financial events. “Blockchain” describes how the parties agree on what happened, not something a road warrior must do before boarding.
On top sits a compact lineup. KAYAK for Business Enterprise supplies the familiar search and booking experience, with corporate policy operating behind it. BMAX links an employer's ERP to air, hotel and car suppliers for authorization and direct ACH settlement, avoiding a corporate card for major bookings. B360 takes a different route: employees can use eligible personal co-branded cards, collect loyalty rewards and still give the company policy control and transaction visibility.
Blockskye Capture, launched in early access in January 2026, tackles the messy spend around a trip. The product identifies likely business purchases as they occur, matches them with travel context and policy, and prepares an audit-ready record. Reimbursement can happen quickly, including an option Blockskye describes as immediate stablecoin payment. The crypto detail is eye-catching; the useful product is the automated matching.

03 / The proving ground
PwC gave the idea a million-booking stress test
Enterprise travel software is easy to admire in a demo and hard to survive at 6 a.m. on a storm day. PwC US supplied the test case. The professional-services firm worked with KAYAK and Blockskye to customize the system for more than 75,000 employees. In the first 20 months, the tool processed more than one million reservations.
PwC reported more than $1 million in ticket savings, alongside better inventory visibility and faster support. It said calls fell by more than 20 percent in the first six months, while the share handled within 20 seconds rose. Those are not laboratory measures. They capture the two audiences a travel platform must satisfy at once: an employee trying to get somewhere and an enterprise trying to control what it costs.
Weather supplied a harsher test in 2024. Blockskye said 99.5 percent of travelers on connected-supplier itineraries affected by Hurricanes Helene and Milton rebooked or canceled digitally, without an agent. The figure does not make agents obsolete. It changes their queue. When ordinary changes resolve themselves, specialists can focus on stranded groups, complex international routes and executives whose itineraries resemble small military exercises.

04 / Who pays, and why
Blockskye sells control to companies large enough to lose it
The customer is not the occasional founder booking a conference. Blockskye aims at multinational programs with thousands or tens of thousands of travelers, complex policy, negotiated airline agreements and finance teams that care about the difference between booked, ticketed, flown, refunded and credited. Publicly named users include PwC US, Diageo and Tripadvisor. The company says it manages more than $1 billion in annual travel spend.
Its business model combines enterprise software and payments with the old-fashioned accountability of a travel management company. Blockskye provides 24/7 support, policy governance, duty of care, VIP service, unused-ticket management and reporting. It also sells the infrastructure and implementation required to connect suppliers and finance systems. Pricing is private, but the pitch stresses transparent economics rather than hidden commissions or incentives that influence which content appears first.
That mix shapes the team as much as the software. Share brought two decades in the travel ecosystem, including co-founding SeaGate Advanced Travel, while Armstrong arrived with startup, venture and travel-innovation experience. The wider leadership group spans agency operations, product and enterprise technology. Blockskye's careers language is plain about the cultural bargain: treat people and partners well, aim high and challenge an industry that is comfortable with inherited process. It is useful rhetoric for a company whose hardest work is neither purely technical nor purely operational. A direct connection is code; getting an airline, an enterprise buyer, a finance department and a service team to trust it is diplomacy.
A familiar search box, loyalty benefits, self-service changes and a human when the itinerary turns strange.
Policy, duty of care, clean data, lower fees and a transaction that lands in the ledger without archaeology.
That alignment is Blockskye's claim to difference. Traditional TMCs such as Amex GBT, BCD and CWT bring global reach and deep service operations. SAP Concur dominates expense workflows. Newer platforms including Navan, TravelPerk and Spotnana offer modern interfaces and infrastructure. Blockskye's unusual combination is direct supplier connectivity, full TMC responsibility and ERP-to-supplier settlement on one shared record.
05 / The next connection
A partnership turns a startup thesis into a distribution test
Capital has followed the operating results. In July 2025, Blockskye raised $15.8 million in a round led by Blockchange, with United Airlines Ventures, Lightspeed Faction and five other investors participating. The money was earmarked for new payment products, international expansion and hiring. In May 2026, Flight Centre Travel Group added a $5 million strategic investment.
The second check came with a larger arrangement. Blockskye, KAYAK for Business and Flight Centre's FCM unit announced plans for an integrated enterprise product. KAYAK contributes the consumer-grade booking interface; Blockskye contributes data, payment and expense infrastructure; FCM contributes service coverage in 95 countries. It is a three-company answer to the market's stubborn trade-off between a pleasant front end, serious global support and financial control.
The arrangement also creates tension worth watching. Blockskye says it is itself a full-service TMC operating across more than 150 countries and territories, while FCM is one of the world's established TMCs. Their collaboration could expand distribution and local servicing, or expose the difficulty of assigning accountability when several capable partners share the trip. Corporate buyers will care less about the organizational diagram than who answers when a traveler is stranded.
There is a broader risk. A shared ledger is only as useful as the connections feeding it. Airlines do not all expose the same content or servicing functions. Hotels are fragmented. ERP integrations are bespoke. Global travel rules vary. Blockskye has to make a technically diverse ecosystem behave as one product without forcing the traveler to see the seams.
Still, the company has chosen a telling place in the market. It is not trying to win by decorating the expense report or adding a chatbot to an old booking stack. It is rebuilding the event beneath them: a business trip as a continuously updated financial object. If that object remains accurate from search to settlement, many familiar chores disappear as consequences. The best outcome for Blockskye may be the least dramatic one - an employee gets home, the supplier gets paid and finance already knows why.
