Offeri is a Finnish startup building an AI quoting software for metal part manufacturers. Quoting based on engineering drawings is a critical but time-consuming part of the job, where AI can save hundreds of hours each month. Were developing the product in close collaboration with our 11 partner shops, with the first version launching at the end of 2025. Our goal is to become the leading quoting tool for European machine shops by the end of the decade.

Risk intelligence that helps enterprises understand, quantify, and reduce physical risk and insurance costs. ScyAI helps enterprises with substantial physical infrastructure stop overpaying for insurance while closing critical coverage gaps. The Problem Insurance pricing is based on broad industry averages, not company-specific reality. Without detailed data on construction quality, mitigation measures, or asset separation, underwriters price defensively. Well-managed companies end up subsidizing weaker peers — or unknowingly retaining risk through coverage gaps. The Solution ScyAI builds quantified, auditable risk profiles by fusing operational data with external hazard models. We translate your physical reality into the actuarial language underwriters use — exceedance curves, probable maximum loss, and engineering credits — enabling you to demonstrate your specific risk quality with mathematical precision. The Results Early adopters report 30–50% premium reductions, translating into seven-figure savings for companies with substantial insurance programs, while simultaneously increasing limits and closing coverage gaps. These savings fund physical resilience investments, creating a compounding cycle: lower risk → reduced premiums → stronger operational resilience. The Team Founded by leaders whove seen enterprise risk from every angle. Founder and CEO Bernhard Rannegger built risk platforms at Swiss Re (joint venture with Palantir), scaling to 50+ enterprise clients including Siemens, Volkswagen, and Maersk. Alex Sidorenko, Head of Risk & Insurance AI, was named FERMA Risk Manager of the Year after saving $13M+ annually using the exact methodology ScyAI now automates. Dont buy insurance. Sell your risk profile.
