Sequen AI

Sequen AI (operating at sequen.ai) is an AI-native behavior design platform engineered for enterprise consumer companies seeking real-time personalization at scale. Founded by Zoë Weil (CEO) and Ethan Benjamin (CTO), the company disrupts traditional recommendation systems by pioneering Large Event Models (LEMs), a novel approach to learning from sparse behavioral sequences without requiring billions of users. Under the hood, Sequen’s LEMs generalize consumer behavior patterns in sub-second inference, enabling dynamic user embeddings that adapt in real time. This allows enterprise-scale businesses to deliver hyper-personalized experiences—driving measurable revenue growth, with early adopters reporting over $162 million in incremental revenue within seven months. Backed by a $22 million total funding round, including a $16 million Series A co-led by White Star Capital and Threshold Ventures with participation from Greycroft, Sequen positions itself as the first foundational model for behavioral personalization.
