Descriptiontext

Mercor S.A. is a Polish manufacturer of passive fire protection systems headquartered in Gdańsk and founded in 1988, employing 251-500 people. The company's core product portfolio spans two categories: natural smoke and heat exhaust ventilation (NSHEV) systems, including the mcr LAM louvered vents, mcr OSO THERM 75 smoke exhaust windows, and continuous rooflights and skylights under the mcr PROLIGHT family; and fire ventilation systems such as fire dampers, smoke exhaust fans, and control units. Products are CE certified under EN 12101-2, EN 14963, and EN 13501-5, and the company obtained APF-1958 fire and safety certification for mcr LAM in June 2025.

The business operates a B2B project-based distribution model, supported by four Polish offices (Gdańsk HQ, Mikołów, Warsaw, Kraków) and international subsidiaries in the United Kingdom, Romania, Slovakia, Czech Republic, Hungary, Ukraine, and Spain. Revenue is generated through sale of certified fire protection hardware, supplemented by recurring professional maintenance and inspection services, a BIM/CAD model library, and product configurators aimed at architects, contractors, and fire safety specifiers. The October 2025 divestiture of the NSHEV and fire ventilation business to Kingspan Group is a material portfolio change, with the residual company pivoting toward rooflights, the newly launched mcr WIP LDX multi-zone fire ventilation system, and the data center vertical. The input also contains data attributing an AI hiring platform and AI training data supplier business to Mercor; on first-party evidence (website, firmographic data, product catalog, leadership team of Krzysztof Krempeć), this analysis treats the Polish passive fire protection manufacturer as the primary entity.

VentureBeatFour AI supply-chain attacks in 50 days exposed the release pipeline red teams aren't coveringFour supply-chain security incidents hit OpenAI, Anthropic, Meta, and TanStack within 50 days, exposing a critical gap in AI vendor security evaluations: existing red-team exercises, system cards, and AISI evaluations do not cover release pipelines, CI runners, dependency hooks, and packaging gates. The incidents included a self-propagating npm worm called Mini Shai-Hulud that obtained valid SLSA cryptographic provenance by hijacking TanStack's own trusted release pipeline, a credential breach at OpenAI affecting two employee devices, an Anthropic Claude Code source map leak exposing 513,000 lines of internal agent architecture, and a LiteLLM supply-chain poisoning that cascaded into a 4TB breach at Mercor and triggered Meta to freeze its partnership with the data startup. The article argues that model red teams and release-pipeline red teams are two separate disciplines, and only one is being consistently funded by frontier AI labs.GizmodoAI Training Data Giant Mercor Is Reportedly Looking to Buy the Work You Did at Your Old JobAI training data company Mercor is reportedly offering payment to professionals in exchange for purchasing their prior work materials from previous jobs, including domain-specific work like visual effects production data. The company has been approaching workers across industries, asking for specialized materials that would typically be employer-owned and protected by confidentiality agreements and intellectual property laws. The report comes amid Mercor's recent data breach where approximately 4TB of sensitive data, including candidate profiles and PII, was reportedly stolen by hackers.
