In an era defined by geopolitical fragmentation, maritime instability, supply chain disruption, and rising regulatory pressure, decision-makers can no longer rely on reactive risk management. They need foresight. Precision. Context. NS Consultancy Global (NSCG) was founded to provide exactly that. We are a boutique strategic advisory firm specializing in geopolitical intelligence, maritime security, and risk resilience. Our mission is to help organizations anticipate disruption, strengthen protection, and operate with confidence across complex global environments. Our approach integrates structured intelligence synthesis, regional expertise, and real-world operational insight to translate global developments into actionable strategic guidance. Rather than offering generic reports, we build long-term advisory relationships. We decode early signals, assess systemic risk exposure, and provide discreet counsel that enables informed decision-making in high-uncertainty environments. As a growing startup, we are assembling a network of senior geopolitical and maritime advisors across regions. We value intellectual rigor, strategic thinking, and independence of judgment. NSCG is not built to be loud. It is built to be precise.

Thor’s Hall is building a performance-based network for creators, publishers, marketers and online communities. We help partners monetize their audiences without having to build the technical infrastructure themselves. Thor’s Hall handles dedicated landing pages, campaign tracking, reporting and partner management while our partners focus on bringing quality traffic through the channels they already understand. Our model is simple: if a partnership generates revenue, everyone involved shares in the results. We currently focus on online gaming and iGaming, with the goal of building a wider network of creators, publishers and growth partners across multiple markets. We are still early, which means the people joining now have the opportunity to help shape how Thor’s Hall grows, test new acquisition strategies and potentially develop long-term partnerships as the network expands.

We're here to change the way people use insurance - safely, compliantly, and on their terms. AI is increasingly where people turn to handle things like insurance. They’re complex products, with real life relevancy, and they’re often not explained well by their providers. That’s great in principle, but it creates real problems for insurers, customers, and regulators - a lot of the machinery that exists around agents today is simply not built for regulated products. Marrow is building the platform that fixes that: the compliance-grade infrastructure that every AI insurance agent runs on. We're live with Aviva, one of the UK's largest carriers, and building a pipeline across the UK and Europe. We’re on the path to regulated status in our own right, are VC-backed, and have a small team that's moved faster than most companies ten times our size. Off the back of a recent fundraise, we’re hiring a small number of high-leverage roles to help us move forward in leaps and bounds.
