Sequen, a New York City-based artificial intelligence company focused on in-session personalization for enterprise consumer applications, has raised $16 million in Series A funding, bringing its total funding to $22 million.
The round was co-led by White Star Capital and Threshold Ventures, with participation from existing investors including Greycroft, which had previously led the company’s seed round. The new capital will be used to accelerate product development and expand hiring as demand from enterprise customers continues to grow.
Sequen has developed a proprietary platform built around what it calls Large Event Models, designed to enable real-time personalization and behavioral optimization without requiring the massive datasets and infrastructure traditionally associated with such systems. Its technology processes live user interactions such as clicks, scrolls, and conversions to dynamically adjust rankings and recommendations within applications.
The company’s infrastructure is optimized for sub-20 millisecond decision-making, allowing enterprises to deliver highly responsive and adaptive user experiences. By focusing on behavioral data rather than identity-based tracking, Sequen aims to address data sparsity challenges while also reducing reliance on traditional tracking methods such as cookies.
Sequen reports that it has already deployed its platform with Fortune 500 companies, delivering measurable improvements in conversion rates and revenue within days of implementation. The company has also introduced RankTune, a tool that enables internal teams to build and iterate on models without managing complex infrastructure.
Founded by CEO Zoë Weil, Sequen has scaled from concept to production in under 18 months and now processes more than 20 billion monthly requests. Its team includes leaders from organizations such as Google DeepMind, Anthropic, Meta, and Etsy. The company recently added Raphael Louca, formerly of Meta, as Chief Product Officer.
The funding will support continued expansion as enterprises increasingly seek AI-driven solutions to enhance customer engagement, personalization, and revenue generation.
KEY QUOTES:
“Modern consumer technology isn’t just recommending content anymore, it’s shaping behavior over time. What we’ve built is the ability to do this without needing billions of users, solving the data sparsity issue enterprise companies face. We train on behavior, not identity, effectively replacing the cookie and enabling real-time optimization for consumer-scale businesses.”
Zoë Weil, Founder And CEO Of Sequen
“Zoë is a once-in-a-generation founder. Her entire career has been spent building and scaling the ranking systems that drive revenue for the world’s largest enterprises. Our conviction was immediate. When a founder combines that depth of domain expertise with this level of execution, our job as investors is simple: remove every obstacle to global scale.”
Eddie Lee, General Partner At White Star Capital
“The consumer internet has fundamentally changed. User expectations have been reset by AI, and every major platform is now scrambling to catch up. Sequen has already proven, repeatedly, with Fortune 500 companies, that their AI drives real revenue. This is not an efficiency play. This is enterprise-ready AI that makes money, and Sequen’s platform is going to become foundational infrastructure for every consumer company that wants to compete in the AI era.”
Lisa Xu, Partner At Threshold Ventures
“We’re constantly looking for ways to make the Fetch app more rewarding for our users and we have some of the best AI scientists in the industry working on improving conversion every day. Sequen built on that foundation and helped us unlock a substantial lift in conversions, showing us what’s possible when a world-class internal team and the right external partner pull in the same direction.”
