Maverick
Maverick is a San Francisco AI startup that generates personalized videos at scale for ecommerce brands. A merchant records one short base video, and Maverick's generative AI clones the voice and reshapes it to greet each customer by name across email flows - welcome, post-purchase, abandoned cart and more. The platform layers on inbox-placement optimization and automatic subject-line A/B testing, and plugs natively into Klaviyo. Founded in 2021 by Eitan Winer and Debarshi Chaudhuri, Maverick sells the idea that online shopping should feel a little more like being recognized by name at your neighborhood store.
