Blok System Supply

What Blok System Supply does

Blok System Supply B.V. is a Dutch contract manufacturer of mechatronic products, founded in 1985 and headquartered in a 5,000+ m² facility in Velsen-Noord, Netherlands. The firm operates an integrated, one-roof production model spanning co-creative engineering, CNC machining (Mazak/Hypermill), 3D printing in plastics and metals, in-house assembly, quality assurance, and global distribution, organized around an 8-phase New Product Introduction (NPI) process that embeds manufacturability and supply chain qualification from initial concept through serial production. It specializes in high-mix, low-volume machine building for OEM customers, with project volumes ranging from single prototypes (1–10 units) to mid-volume serial production (1,000+ units), and holds ISO 9001:2015, ISO 13485 (medical), and UL certifications.

The company targets ambitious product businesses and OEM clients in medical technology, industrial automation, robotics (AGVs, drones), energy and climate, transport/mobility, and agri-food, and explicitly positions itself as a 'hidden partner' that handles everything from concept engineering through worldwide DDP delivery — including medical devices such as UVC disinfection robots and blood analysis machines built under ISO 13485. Its go-to-market is consultative enterprise field sales driven by a 5-step project intake form (project phase, sector, volume, budget), with a two-business-day response commitment, supported by a CEO-led and HR-driven organic marketing approach emphasizing LinkedIn presence, regional industry events (Techport Technologieweek), and STEM/community outreach programs.

Revenue is generated primarily through project-based engineering and contract manufacturing fees under the NPI process, with downstream recurring revenue from ongoing serial production and supply chain management once products transition out of development; pricing is quote-based and project-specific, with no public price list. The company is privately held, founder-led (CEO Martijn Witteveen; founder Anouk Blok), employs approximately 40 people (~15% female, ~85% male, average age 40), and has no disclosed external funding, parent organization, or institutional investors.
