About Savvy Wealth:At Savvy Wealth, we are at the forefront of transforming the wealth management industry, currently valued at $545 billion in the US, which has long been hindered by outdated practices and minimal technological integration.

Our digital-first solution enhances the delivery of human financial advice, allowing advisors to leverage AI-driven software, automated marketing and sales efforts, and streamlined back-office operations to expand their reach and devote more time to client interactions.With over $105 million raised from prominent investors such as Thrive Capital, Index Ventures, and Canvas Ventures, our team comprises skilled repeat founders and operators from companies like Airbnb, Square, and Facebook. We have achieved remarkable growth—over 600% in the last 18 months—and have surpassed $2.2 billion in assets under management in less than three years.
