Hyperplane, a San Francisco-based startup, has secured a $6 million funding round led by Lachy Groom, a former Stripe executive, and other prominent investors. The company focuses on helping banks utilize their first-party data to create personalized customer experiences by predicting user behavior. They aim to expand beyond the banking industry, although currently, they are working with about a dozen banks in Brazil and plan to expand to the U.S. The team, led by co-founders Felipe Lamounier, Daniel Silva, Rohan Ramanath, and Felipe Meneses, are leveraging their expertise in AI and extensive industry experience to develop personalization models for banks. Their technology has already shown significant impact, such as increasing transaction volume by 46% for a neobank in Brazil and predicting customer behavior to reduce churn rates.
