Sequen AI, founded in 2024, is a New York-based startup that has developed what it calls the world's first Behavior Design Engine for the enterprise. The platform represents a departure from conventional personalization, employing Large Event Models (LEMs) to move beyond static user profiles and shape actual user behavior in real-time. It achieves this by dynamically re-ranking experiences within a single session, leveraging reinforcement learning to process live behavioral signals with sub-25ms latency.
The company's technology operates at considerable scale, processing over 20 billion monthly requests. This performance has delivered measurable results for its initial customer base across retail, marketplaces, and travel verticals, generating over $162 million in incremental revenue lift for its first five clients within under 18 months. Sequen AI serves Fortune 500 companies and secured $16 million in Series A funding.
The founding team brings experience from search and discovery roles at Etsy, Yahoo, HookLogic, and Anthropic, bringing what the company describes as hyperscale DNA to its technical challenges. The engineering work sits at the intersection of neural networks, reinforcement learning, real-time systems, and low-latency processing.
