Sequen builds real-time personalization technology and ranking infrastructure, offering access to frontier and real-time ranking models through its RankTune APIs. The company claims its large event models generalize streams of user events—hovers, conversations, session behavior—allowing sub-20-millisecond decisioning without relying on user identity. Sequen reports processing about 10 billion monthly requests within 18 months of operation and has a 14-person team with hires from DeepMind, Meta and Anthropic. Early customers include a large furniture retailer, Fetch Rewards, a streaming media company and an online travel agency, with initial contracts in the seven-figure range and reported revenue lifts (e.g., 7% for a furniture customer and 20% net revenue lift for Fetch Rewards in under 11 days). The product is priced by requests per second with tiered discounts and the company markets its approach as more privacy-forward than third-party cookies.
