What Interpersonal Gmbh does

Interpersonal GmbH (also operating under the historical name interpersonal III GmbH) is a privately held, family-owned aviation personnel services firm headquartered in Hamburg, Germany, founded in 2003 by Captain Erhard Walther and currently led by Managing Director Christoph Walther. The company serves airlines, aviation operators, ground handlers, and flight schools by sourcing, vetting, and placing aviation professionals — primarily pilots, cabin crew, dispatchers, and technicians — and by operating a portfolio of four service lines under the brands career.aero (aviation job portal with near-100% market penetration among German professional airline pilots), EAQC (European Aviation Qualification Center, providing validated psychological and psycho-motor selection procedures), skypool (crew secondment under equal treatment / equal pay arrangements), and an internal IT services division that develops proprietary recruitment and assessment platforms.

The technology stack comprises the cloud-based career.aero job portal and applicant management system, the EAQC IT test platform (eaqc.aero) with EU-guideline-calibrated WBT test batteries, the proprietary MozARD psycho-motor aptitude test inventory, the skillnavigator App / BQConnect for remote candidate assessments, and the ip Certificates (ipcert.io) web application for issuing and tracking digital certificates for Ready-Entry Pilot and Ab-Initio programs. The company sells standardized assessment products (BQ ip Ready-Entry at €429, BQ ip Ab-Initio at €359, BQ ip Ab-Initio connect at €499 per candidate) through its own online shop and to employer clients, while recruitment services are monetized via job-posting and placement fees, crew secondment via staffing fees, and IT services via SaaS and white-label career portal deployments. Customer-side demand is anchored by enterprise relationships with Condor, Eurowings, DHL Aviation, Lufthansa group entities, TUI fly, Discover Airlines, SunExpress, and others, supplemented by recognition partnerships with flight schools such as EIAB, RWL, and TFC Boeing Training Center.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• CAE: CAE is a global aviation training and crew resourcing major, operating pilot training centers and crew placement services worldwide. It addresses the same underlying pilot-shortage problem as Interpersonal but at vastly larger scale and with a broader portfolio spanning simulators and full type-rating programs.
• Resource Group: Resource Group is a global aviation services group providing crew leasing, training, and personnel solutions to airlines. Its crew-leasing business directly competes with skypool, and its scale gives it broader incumbent reach across European and international carriers.

Direct peers

• Aeropeople: Aeropeople is a UK-based aviation recruitment and personnel services firm placing pilots, engineers and cabin crew. Like Interpersonal, it combines aviation-specific job board reach with staffing/secondment services for airlines and MROs, making it the closest UK analogue to Interpersonal's German franchise.
• Contractair: Contractair specializes in contract and temporary staffing for the aviation industry, including flight crew, cabin crew and engineering personnel. Its focus on flexible crew deployment overlaps directly with Interpersonal's skypool secondment offering.
• Aviation Job Search: Aviation Job Search is one of the largest online aviation job boards globally, used by pilots, cabin crew, engineers and dispatchers. It competes directly with career.aero for employer job-posting spend and candidate traffic in the European market.
• Aviation Recruitment Group: Aviation Recruitment Group is a specialist aviation headhunting and permanent placement firm serving airlines, MROs and business aviation operators. It is comparable to Interpersonal's active search and headhunting services delivered through career.aero.
• AviationCV: AviationCV is an aviation-focused CV database and job platform primarily used by cockpit and cabin crew professionals. It competes directly with career.aero for pilot candidate mind-share and airline employer recruitment budgets across Europe.
• GMP Personnel: GMP Personnel is a German aviation staffing specialist providing pilots, cabin crew and technical personnel on temporary and permanent contracts. It is the most direct German competitor to Interpersonal's skypool crew secondment business and recruitment services.

Others

• Lufthansa Aviation Training: Lufthansa Aviation Training is both a partner customer of Interpersonal and a broader competitor offering pilot and cabin crew selection, training and assessment under its own Lufthansa group brand. It is comparable because it addresses the same aviation selection and qualification market as EAQC, but operates at much larger scale as part of the Lufthansa group.

Emerging players

• WorkAir: WorkAir is an emerging aviation job platform targeting pilots and cabin crew across Europe. While smaller and less established than career.aero, it represents a newer-generation competitor aiming to digitize aviation recruitment in the same niche.
