What Onstream Group does
Onstream Group is a Netherlands-headquartered industrial services company, founded in 1978 by two British engineers, that delivers three integrated service lines — Manpower & Recruitment, Logistics, and Asset Integrity — to clients in oil & gas, mining, maritime, petrochemical, and infrastructure construction. The company is the legal parent of ONSTREAM GROUP HOLDING B.V. and operates through regional subsidiaries including Onstream Project Services B.V. and Onstream Flex B.V. (Netherlands/EMEA), PetroGas Gabon SA and Onstream Transport Gabon SA and Energy Resources Gabon (Gabon), ASC Nigeria Ltd. (Nigeria), Onstream Oilfield Services Mozambique Limitada (Mozambique), and Onstream Kazakhstan LLP (CIS). Geographic coverage spans Europe (headquarters in Den Haag), Sub-Saharan Africa (Gabon, Nigeria, Mozambique), and CIS (Kazakhstan), with service delivery including skilled and unskilled staffing, equipment rental and transportation, and on-/offshore asset integrity solutions such as rope access, scaffolding, blasting and painting, fireproofing, and anti-corrosion treatment.
The company's core technology stack consists of a QHSE Integrated Management System certified under ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 39001:2012, along with VCA**, VCU, and Achilles prequalification, plus an internal Onstreamcloud remote desktop platform. These systems support compliance monitoring and distributed workforce operations but do not represent proprietary differentiated technology. The business model is professional services-based: revenue is generated through staffing fees (covering sourcing, payroll, tax, national content compliance, insurance, visa and travel services), logistics and equipment-rental contracts (cargo, fuel, mining, refrigerated, and dangerous-goods transport plus OEM spare parts), and asset-integrity project work. Pricing is quote-based and tailored to project scope, duration, industry, and location, with no publicly disclosed price list. The go-to-market is enterprise field sales — direct engagement with major oil & gas operators and contractors — supplemented by industry events (e.g., Maritime Industry Fair in Gorinchem) and a corporate blog/news channel.
In July 2023 Onstream acquired Antro Werkt B.V., a Dutch food-service personnel recruiter, marking the company's first material diversification beyond industrial verticals into domestic food-service staffing. The group remains privately held under ONSTREAM GROUP HOLDING B.V. with no evidence of external institutional or PE ownership, no public listing, and no disclosed funding rounds. Reported headcount is 251-500, and revenue is not publicly disclosed.
