About
Forum is building the first exchange to trade on cultural attention. We create indices from search, social, and streaming data to measure what the world cares about, enabling users to go long or short on changes in relevance. Attention is the primary driver of business success in the digital age, but it has never been directly tradable. Forum introduces attention as a new asset class for managing cultural and demand risk.
