Ypsilon.NET AG

What Ypsilon.NET AG does

Ypsilon.NET AG is a German travel technology company founded in 1994 and headquartered in Frankfurt, with additional operations in Leipzig (Python Dev Center), Burgess Hill, UK (Ypsilon UK Ltd for UK/Ireland), and Spain. The company operates a modular, multi-source travel technology platform combining Travel IT, payment processing, and fraud prevention in a single SaaS stack. Its core product, FlightPro, is a multi-GDS/CRS booking engine aggregating content from all major GDS (Amadeus, Sabre, Travelport), FareLogix/NDC carriers, 260+ low-cost carriers, 20+ charter operators, rail, hotels, and car rentals through a single XML API. The platform serves airlines, OTAs, tour operators, travel agencies, consolidators, TMCs, and corporate buyers across 5,000+ customers and 80,000+ booking portals globally, with infrastructure spanning 280+ physical servers and 120+ virtual servers across multiple data centers.

The company's revenue model blends SaaS subscriptions for booking engines (FlightPro, ETACS, XML API, Profiles) with transaction-based payment fees (via direct connections to 25+ PSPs/acquirers and virtual card providers), content licensing and distribution, and managed PCI DSS services (Norris token proxy). FraudClear is a differentiated add-on that performs ML-assisted payment and loyalty fraud detection directly at the PSS/GDS source, integrated with major reservation systems (Amadeus Altea, SabreSonic, Travelport, Navitaire, Raddixx, NextRes). The company holds PCI DSS Level 1, ISO 27001, PSD2/SCA, GDPR, and IATA NDC Level 3 certifications, and is registered with VISA Europe as a Merchant agent. Distribution is achieved via XML API/SaaS, white-label/embedded deployments, and channel partners including Sabre Mosaic, Amadeus, Travelsky, Peakwork, and metasearch engines.

Ypsilon is privately held by founder/CEO Hans-Joachim Klenz, operating as a German AG (Aktiengesellschaft) with no external funding rounds disclosed. Key management includes Chairman of the Supervisory Board Dr. Siegfried Weiss, VP Sales & Marketing Patrick Alain Coulomb, Head of HR Stefan Kovacs, and Head of UK/Ireland Sue Stempt. The company is bootstrapped and profitable by implication, competing against larger GDS-anchored platforms (Sabre, Amadeus, Travelport) and specialized fraud vendors by offering a more focused, mid-market, integrated Travel-IT-plus-payments stack. Notable enterprise customers include KLM, Deutsche Bahn, HanseMerkur, Travelsky, and JT Touristik, with fraud prevention cases highlighting measurable reductions in fraudulent bookings and manual review effort.

Revenue model

1. SaaS Booking Engine Subscriptions: Ypsilon provides its travel booking engines (FlightPro, XML API, Agentweb, Hotel IBE, Car IBE) as Software-as-a-Service (SaaS). Customers pay recurring subscription fees to access the platform, with implementations possible within one day. The SaaS model provides multi-tenant, cloud-hosted access to booking engines, fraud prevention, payment services, and ticketing automation.
2. Payment Processing and Transaction Fees: Ypsilon operates as a Payment Service Connector, providing the technical infrastructure for integrated booking and payment flows. The platform connects merchants to acquiring banks, PSPs, and virtual credit card providers, generating transaction fees per payment processed. Services include fraud check, reconciliation, and post-booking interaction within GDS/CRS environments.
3. Content Distribution and Licensing: Ypsilon licenses its content aggregation platform to travel companies, providing access to multi-GDS content, NDC airline content, low-cost carrier content, charter flights, and rail content. Airlines and travel suppliers access thousands of agencies and customers worldwide through Ypsilon's distribution platform, generating licensing revenue from both content distribution and technology licensing.
4. PCI DSS and Security Solutions: Ypsilon offers PCI DSS Class 1 compliant token proxy solutions (Norris), enabling travel companies to store credit card data securely and comply with PCI DSS standards. The solution simplifies or eliminates the need for full PCI DSS certification, generating revenue through implementation and ongoing service fees.

Partnerships

Four partnerships are on record, tiered core.

• SabrecoreTechnology or Integration · 20 January 2026Ypsilon.net connected to Sabre's Mosaic Travel Marketplace as one of five travel technology providers, enabling connected travel sellers to access NDC airline content from 42 airlines within existing GDS workflows. The integration reduces manual workarounds, decreases errors, and allows agencies and corporate buyers to compare NDC offers alongside traditional and low-cost carrier content without separate airline-specific connections.
• AmadeuscoreTechnology or Integration · 26 June 2019Ypsilon integrated Amadeus B2B Wallet Solution within its booking platform, enabling travel agents to automatically generate virtual credit cards within the booking flow. LCC fares representing approximately 25% of total seats in Ypsilon's key European markets can now be paid according to each agency's unique business strategy. Virtual cards can be unique to individual bookings making reconciliation simple whilst reducing fraud.
• IATAcoreStrategic or Co-development Partner · 7 January 2016IATA partnered with Ypsilon for fraud prevention services, integrating Ypsilon's Argus/FraudClear fraud detection system into IATA's Argus fraud monitoring platform. Ypsilon's system is the only one that analyzes bookings from both online and traditional agencies. IATA cited fraud attempts occurring at 0.3% of all credit card flight bookings, causing $640M direct damage to airlines and $220M to travel agencies annually.
• TravelskycoreStrategic or Co-development Partner · 30 August 2013Travelsky, China's largest GDS and third largest globally, partnered with Ypsilon to provide LCC content to over 100,000 Chinese travel agency terminals via XML interface. Travelsky cited Ypsilon's unique combination of booking system expertise, content interfaces, and secure payment processing. Ypsilon processes payments via Wirecard, converting China Union Pay cards to virtual MasterCards for single-transaction use.

Broad incumbents

• Travelport (now part of PE consortium): One of the three major global GDSs, now private-equity owned. Travelport provides GDS content distribution, NDC aggregation, and agency booking tools — directly comparable to Ypsilon's core multi-GDS booking and aggregation stack.
• Amadeus: Largest global GDS with integrated NDC platform and B2B Wallet solutions. Comparable to Ypsilon in providing GDS/NDC content aggregation, corporate booking tools, and travel agency technology — though at far greater scale.
• WebBeds (Webjet): Global B2B accommodation and ancillary aggregator serving OTAs, tour operators, and travel agencies. Comparable to Ypsilon's multi-source aggregation model, with particular overlap in the hotel/car content aggregation layer.
• Sabre: Major global GDS with NDC and Mosaic Travel Marketplace. Sabre operates as both a content supplier and aggregator — comparable to Ypsilon in serving OTAs and agencies via GDS/NDC booking tools, and is explicitly a partner.

Direct peers

• Lleego: Spanish NDC and content aggregation specialist serving airlines and travel agencies. Listed alongside Ypsilon on the Sabre Mosaic Marketplace, directly competing for the same NDC distribution mandate.
• Traveltek: UK-headquartered travel technology provider offering booking engines, cruise/flight/hotel APIs, and dynamic packaging tools to OTAs and tour operators — directly comparable to Ypsilon's FlightPro, ETACS, and Package Tours offerings.
• Peakwork: Dynamic packaging and travel technology provider connecting tour operators, OTAs, and suppliers. Comparable to Ypsilon via their mutual partnership and shared dynamic packaging customer base; both compete for tour-operator technology wallets.
• TPConnects: NDC aggregator and GDS new distribution capability specialist. Listed alongside Ypsilon on the Sabre Mosaic Travel Marketplace, targeting the same OTAs, TMCs, and corporate buyers with NDC content distribution.
• Vibe (travel technology): NDC aggregator and travel technology provider listed alongside Ypsilon on Sabre Mosaic. Targets the same connected travel sellers and corporate buyers with NDC content access — a head-to-head peer in the aggregator layer.

Emerging players

• Duffel: API-first NDC aggregator targeting OTAs and TMCs with modern developer-first booking infrastructure. Comparable to Ypsilon's XML API value proposition but with a younger, AI-era architecture and venture funding.
