ISG International Service

What ISG International Service does

ISG International Service Group (legal entity: ISG Personalmanagement GmbH) is a Vienna-headquartered full-service HR consulting firm founded in 1999, operating across 45+ countries through 60+ offices and 800+ employees. The company delivers an integrated portfolio spanning permanent recruiting, executive search, training and personal development, temporary staffing (Zeitarbeit), interim management, and sustainability-focused consulting (ISG Green). Its customers are primarily multinational enterprises and SMEs across 13 industry verticals — including Automotive, Financial Services, Healthworld, Technology, Transport & Logistics, and Travel Leisure Private — with secondary exposure to public-sector and non-profit clients.

The company's service delivery is built on database-driven candidate searches, professional networks (LinkedIn, Xing), and direct headhunting supported by an in-house Media House team that places job advertisements across online job boards and print channels. Its proprietary ISG Job Portal (isg.com/jobs) handles more than 18,000 job postings annually, with self-service candidate profile management, job alerts, and application tracking. ISG operates specialist sub-brands for sustainability consulting (ISG Green), employer-brand diagnostics (Mystery Recruiting), and leadership development (Offene Online Akademie Führung), and lists an "AI & Future Work" advisory line on its website, though no technical details are disclosed.

Revenue is generated through a mix of transaction fees (typically a percentage of placed candidates' annual salary for permanent placements), fixed-fee project engagements (executive search, interim management), time-and-materials billing (temporary staffing), and program fees (training). Pricing is fully quote-based with no public tiers; all offers are exclusive of VAT and typically run on multi-year contracts with 14-day cancellation notice. Distribution is sales-led through direct consultant outreach, supplemented by a global franchise and member-office network coordinated from Vienna and self-service access via the job portal. The firm is privately held and management-controlled, with no external funding rounds, private equity involvement, or public listing on record.
