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.

CoinIQ was built because most crypto tools only track your portfolio — they don’t help you understand it. Managing multiple wallets and exchanges is still messy, and getting a clear picture of risk, returns, and diversification often means juggling spreadsheets. CoinIQ connects your wallets and exchanges into a single unified view and layers on analytics you’d normally find in traditional finance: performance attribution, volatility, diversification metrics, and drawdown analysis. On top of that, we’ve added an AI insights engine that surfaces rebalancing suggestions and explains why your PnL looks the way it does. We also provide crypto-specific insights like anomaly detection (useful for spotting rug pulls) and portfolio-level news summaries tied directly to your holdings.
