What Serko Online does

Serko Online (legal name Serko Ltd; NZX/ASX: SKO) is a publicly listed New Zealand-headquartered corporate travel and expense management software company. Its core product is the Zeno platform, a cloud-based SaaS solution that lets corporate travelers book and manage complete trips — flights, hotels, rental cars and ground transport — alongside automated expense capture, receipt matching, credit-card reconciliation and policy-driven approvals, all delivered through a network of 100+ travel management company (TMC) partners. The platform aggregates content from all three major GDS providers (Sabre, Amadeus, Travelport), NDC channels (Travelfusion, Sabre NDC-X, Amadeus NDC-X), and hotel aggregators Booking.com and Expedia, and processes roughly US$4.5 billion of corporate travel annually across 7,000+ entities in 180 countries, with 20,000+ bookings per day. Serko also operates Booking.com for Business (powered by Zeno, used by 800,000+ companies on a freemium model) and, following the January 2025 acquisition of GetThere from Sabre for US$12 million, serves the largest global enterprise travel programs with a white-label platform in 70+ countries and 16 languages.

Serko earns revenue through a combination of recurring SaaS subscriptions on Zeno and GetThere (quote-based, sold largely through TMC partners and direct enterprise sales) and transaction-based booking income linked to the US$4.5B GMV flowing through the platform, with a freemium SMB funnel via Booking.com for Business generating volume-led economics. Go-to-market is hybrid: TMC-channel-led for Zeno SMB and mid-market, direct enterprise sales plus white-label for GetThere, and product-led self-serve for the Booking.com for Business SMB base, with US closed-beta direct distribution for the emerging Serko.ai AI travel assistant. The company has sharpened its portfolio in 2024–2025 — divesting InterplX to Cerebri AI, completing the GetThere acquisition, renewing multi-year partnerships with Booking.com, Sabre, Amex GBT and FCM, and standing up a North America hub in Southlake, Texas — while investing in AI (Serko.ai, Intelligent Itinerary) and sustainability (Mission Zero, recognized as 2025 B2B Travel Innovation of the Year).

Expansion highlights6 records

Broad incumbents

• American Express Global Business Travel (Amex GBT): Amex GBT is a leading global TMC and a strategic customer/partner of Serko's Zeno platform. While it both uses Zeno technology and competes for the same enterprise travel management business, its TMC heritage and broader portfolio make it a broad incumbent rather than a pure-tech direct peer.
• Egencia (Expedia Group): Egencia is Expedia Group's corporate travel brand offering online booking and travel management for mid-market and enterprise. It competes with Zeno and GetThere with similar TMC-tech hybrid positioning but benefits from Expedia Group's broader travel content and scale.
• Cytric Travel & Expense (Amadeus): Cytric is Amadeus's corporate travel and expense platform integrating with the Amadeus GDS. It competes with Zeno for enterprise customers, particularly those with strong Amadeus content dependencies, and benefits from Amadeus's NDC content leadership.
• CWT (formerly Carlson Wagonlit Travel): CWT is a major global corporate travel management company and a customer of GetThere. It uses Serko technology but also competes for the same enterprise travel management contracts, creating a hybrid partner-competitor relationship similar to Amex GBT.

Direct peers

• Spotnana: Spotnana is a cloud-based corporate travel platform with an open-API architecture and direct booking capabilities. It directly competes with Serko's Zeno and GetThere platforms in modern enterprise travel tech, and notably hired the same executive (Johnny Thorsen) who later joined Serko's VP Strategic BD role.
• SAP Concur: SAP Concur is the dominant enterprise travel and expense management platform serving global corporations. It directly competes with Zeno and GetThere in the corporate T&E space with overlapping target customers and similar feature sets including booking, expense, and policy compliance.
• TravelPerk: TravelPerk is a fast-growing corporate travel and expense platform targeting SMB and mid-market segments. It directly competes with Booking.com for Business and Zeno's mid-market offerings with its own booking platform, expense management, and recently launched corporate card product.
• Navan (formerly TripActions): Navan is a modern corporate travel and expense platform combining TMC services with proprietary technology. It directly competes with Zeno and Serko.ai by offering AI-powered booking, expense management, and a corporate card to enterprise and mid-market customers globally.

Others

• Booking.com for Business: Booking.com for Business is powered by Serko's Zeno technology under a five-year partnership renewed June 2024. While the platform is owned and operated by Booking Holdings, it is technically Serko's product and provides the SMB funnel (800,000+ companies) to the broader Serko ecosystem.

Regional players

• Flight Centre Travel Group: Flight Centre Travel Group (FCTG) owns FCM and Corporate Traveller - both major TMC partners of Serko distributing Zeno. While headquartered in Australia with strong APAC presence, FCTG competes with Serko's Zeno enterprise offering while also being a key distribution channel.
